Dual-Feed 350A 8/8-TPA & 10/10
GMT Fuse Alarm Panel
Power :: 009-8005-0810
1.1 Overview
Telect’s dual-feed 350A fuse panel with alarms provides
power protection for data and communications equipment
ranging from ¼A to 50A. The white panel includes 16
TPA output fuse holders (8 per side) and 20 GMT
holders (10 per side).
Sides A and B are electrically independent except
for the replaceable alarm card, which contains power
status LEDs for each side and power-fail and fuse-alarm
relays. Relay contacts are Form C for external visual
and audio indicators.
Hardware is included for ush or 5-in. extended mounting
in a 23-in. or 19-in., EIA or WECO rack. (The 19-in.
rack must have an equipment mounting aperture of at
least 17.5 in.) Visit our website for ordering Telect
accessories: fuses (3A-50A TPA & ¼ A-15A GMT),
ETSI bracket kit, spare alarm card, and more.
Model 009-8005-0810 is UL Listed (E139903), NEBS
compliant, and RoHS compliant.

1.2 Installation
1.2.1 Important Installation Guidelines
• Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore, consideration should be
given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma)
specied by the manufacturer.
• Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air ow required
for safe operation of the equipment is not compromised.
• Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
• Circuit Overloading - Consideration should be given to the connection of the equipment on the supply circuit
and the effect that overloading of the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
• Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).
• Disconnect Device - A readily disconnect device shall be incorporated in the building installation wiring.
1.2.2 Inspection
Please read and understand all instructions before starting installation. If you have questions, contact Telect
When you receive the equipment, carefully unpack it and compare it to the packaging list. Please report any
defective or missing parts to Telect Quality at [email protected] or call 1.509.926.6000.
Telect is not liable for transit damaged. If the product is damaged, please report it to the carrier and contact Telect.

ALERT
!
ALERT! Only use components and crimping tools approved by agencies or certifying bodies recognized
inyourcountryorregionsuchasUnderwriter’sLaboratories(UL),TUV,etc.
6. Use a listed (approved) crimping tool to attach a
listed (approved), dual-hole compression lug onto
a suitable ground wire. (The size of the ground
depends on the input interruption device.)
7. If required, lightly coat anti-oxidant on the lug and
grounding surface on the side of the panel.
8. Connect the lug using the ¼ - 20 bolts and at
washers provided, as shown in Figure 4.
9. Tighten the bolt to 50 in.-lb (5.5 N•m).

WARNING
!
WARNING!Beforeconnectinginputpowercables,makesureinputpowertopanelisturnedoff.
10. Make sure the input power is off (open breaker, dummy fuse, or open fuse holder at the primary power
distribution unit [PDU]) before connecting this panel’s input cables to the PDU.
11. For input wiring — wiring used as inputs to this distribution panel — crimp dual-hole compression lugs onto #1
AWG to 600MCM copper wires. The choice of input wiring depends on the following criteria:
• Input interrupt device rating affects the size of input wiring.
• Ambient operating temperature affects the type of input wire insulation.
12. See Section “1.4.1 Compression Lugs” on page 11 to select your lugs. Insulate the lug barrels with UL94 V-0
rated heat-shrink tubing.
13. Clean the terminals and lugs with a non-abrasive, non-metallic pad.
14. If required, lightly coat anti-oxidant on lugs and input BATT and RTN terminals.

15. Connect the lugs to the input terminals on the back
of the panel, as shown in Figure 5.
16. Tighten the lugs to 140 in.-lb (~15½ N•m).
17. Make sure the TPA and GMT fuse positions are
either empty or contain dummy fuses (phoney,
inoperative, all-plastic slugs). If necessary, pull
out the TPA carrier about an inch from its holder
to disengage the TPA fuse, as shown in Figure 6.
18. Enable the fuse or breaker at the PDU (400A max.)
to turn on Feed A to Side A of the panel and then
check the voltage and polarity at input connectors
of the panel. Also, check that:
• Power A LED on the front of the panel turns on
(green).
• Power BLED must turn red.
19. With A LED green (normal operation) — but with
B LED off (failure operation)— test the power-fail
relay and contacts at A PWR alarm terminals on
the rear of the panel:
• Expect continuity (0Ω) between Terminals Cand NC.
• Expect an open circuit (∞Ω) between Terminals C
and NO.
20. Also, test the fuse alarm relay contacts at the
FUSE alarm terminals on the rear of the panel.
• Expect continuity (0Ω) between Terminals Cand NC.
• Expect an open circuit (00Ω) between Terminals C
and NO.

21. Repeat Steps 18 through 20 to power up Side B.
Aand Bpower LEDs must both be green.
22. Make sure none of the fuse positions contain
operable fuses.
23. For TPA output wiring, crimp single-hole lugs onto
one end of the #18 to #6 AWG copper output wires,
as required by NEC. (Work with one output wire
at a time.)
24. Clean the panel terminals and lugs with a non-abrasive,
non-metallic pad.
25. If required, lightly coat anti-oxidant on the lugs and
output BATT and RTN terminals.
26. Connect the lug to the terminals, as shown in
Figure 7. (NEC species only one lug and load at
each output terminal.)
27. Tighten the nuts to 20 in.-lb (~2.3 N•m).
28. Connect the other end of the output wire to load.
29. For GMT output wiring, use #22 to #12 AWG
copper wire. (Work with one wire at a time.) At
the panel end of the wire, crimp a single-hole
ring or fork lug, as required by NEC.
30. Clean the panel terminals and lug (if applicable)
with a non-abrasive, non-metallic pad.
31. If required, lightly coat anti-oxidant on lug/wire and
output BATT and RTN terminals.
32. Connect to the terminals, as shown in Figure 8.
(NEC species only one load at each output terminal.)
33. Tighten the panhead screws to no more than 6.3
in.lb (~0.7 N•m).
34. Connect the other end of the output wire to load.
ALERT
!
ALERT! GMT fuses have a small inherent electrical
resistance resulting in a small inherent power loss.
Forthisreason,theGMTfusemanufacturer
recommends that the load for GMT fuses up to and
including 7.5A not exceed 80% of the fuse rating
and that the load for GMT fuse sizes between 10A
and 15A not exceed 70% of the fuse rating. For
example,theloadfora15AGMTfuseshouldnot
exceed10.5A(15Ax.70=10.5A).

35. Make sure the load devices are switched off and
then install the fuses:
NOTE: Under load, TPA modules are disconnect
devices only and must not be used to reconnect
power to enabled equipment loads. Reconnecting a
TPA module under power with an enabled load may
damage the TPA module.
• For a TPA fuse, pull out TPA fuse carrier and insert
operable fuse, as shown in Figure 9.
• For a GMT fuse, pull out the dummy fuse, and
insert an operable fuse, as shown in Figure 10.
36. Test power and polarity at input of each equipment load.
37. If possible:
• Temporarily replace one of the operable TPA fuses
with a blown fuse to check that the TPA Fuse LEDs
light red. Also, check the FUSE alarm terminals on
the rear of the panel:
− Expect an open circuit (00Ω) between Terminals
Cand NC.
− Expect continuity (0Ω) between Terminals
Cand NO.
Re-install the operable TPA fuse before proceeding.
• Likewise, replace one of the operable GMT fuses
with a blown fuse to verify that the FUSE alarm
terminals are also as specied above. Then re-install
the operable GMT fuse before proceeding.
38. If desired, connect the remote external audio/visual
alarm indicator wires (solid or tinned wires, #26 to
#20 AWG) to the PWR and FUSE alarm terminals,
as implied in Figure 11.
39. Carefully re-install the rear cover.
40. Record the TPA and GMT output destinations in
accordance with operating company procedures
and guidelines.
41. Turn on equipment loads one at a time to verify the
proper operation of the loads.
