Only authorized, qualified, and trained per-

ment. Refer to datasheets for full product

specifications.

Observe all local and national electrical,

environmental, and workplace codes.

Each power shelf should be fed from a dedi-

cated AC branch circuit of a Terra Neutral

(TN) power system.

If a line cord(s) is (are) used as the AC

connection means, the plug end of the cord

is considered to be the primary disconnect

means, and reasonable access must be

given to the plug and receptacle area. The

receptacle must be fed with a breaker or

fuse according to Table 4.

For hard-wired AC connections, a readily

accessible disconnect device shall be incor-

porated in the building installation wiring.

Select a wall breaker and wire sizes accord-

ing to Table 4.

CAUTION:

FUSING

Use double hole, UL listed lugs for all DC

connections to prevent lug rotation and inad-

vertent contact with other circuits.

Class 1 wire is recommended for all DC con-

nections. Minimum wire sizes are shown in

Table 5. In practice, loop voltage drop con-

siderations will usually dictate larger than

minimum safe wire size.

Connection and mounting torque require-

ments are listed in Table 7.

Lambda does not recommend shipping the

rack with the power modules installed. Power

modules should be shipped in separate boxes.

This system utilizes a dual or individual feed AC architecture (Figure 1 & Figure 2).

2.2.2.1

Dual

feed

A system with a dual feed AC architecture feeds power module slots 0 & 1 with feed 1, and

power module slots 2 & 3 with feed 2. The AC connections on the shelf are made via rear

accessed compression style terminal blocks see Figure 6. These terminal blocks will accept up to

a maximum of a 10 AWG wire, and should be torqued to 6 in-lbs. Keep this wire size limitation

in mind when sizing the quantity and size of the power modules. Size your AC breaker and

wiring according to Table 4.

2.2.2.2

Individual

feed

A system with an individual feed AC architecture feeds each power module slot with an AC feed.

There are two different styles of individual feeds for this system.

The first style of connection is made via rear accessed compression style terminal blocks see

Figure 6. These terminal blocks will accept up to a maximum of a 10 AWG wire, and should be

torqued to 6 in-lbs.

The second style is made via rear accessed IEC320 receptacles, see Figure 8. The connections

should be sized with an AC service no larger than 15 amps. Keep this limitation in mind when

sizing the power modules. Securing brackets are available to hold the IEC320 AC cords to the

shelf, see Figure 9 for more information. Size your AC breaker and wiring according to Table 4.

sizing

To size your AC feeds properly, use the example below. Failure to size the AC breaker and wiring

properly can result in nuisance breaker trips or even fire. If you anticipate future growth, size the

AC breaker and wiring for the expected future capacity.

Use section 2.2.2 to determine your AC input architecture, for example a dual feed.

Determine the quantity and model number of the power modules that will be used, for example

two TH120048 (48V, 25A).

Determine the sites AC input nominal AC voltage and compare it to Table 3 for power module

compatibility, for example, the TH120048 power module will accept either low line or high line

AC voltage.

Revision A4 : August, 2009

Page. 8

THR4-SSERIES

POWER SYSTEM

For this example we will assume that future growth is necessary so we will size the AC feed for

four power modules. Using Table 4, each AC feed, to the pair of TH120048, power modules will

require will require a 20 amp breaker with 12 AWG wire, at high line, per feed.

NOTE: Under-sizing your AC breaker and wiring could cause nuisance breaker trips and system

outages. ALWAYS

Circuit

Wire

Diagram

Each system is equipped with 2 unprotected bulk output connections; one set located on each

side of the rear of the shelf. The THR4 rack will only accept lugs and THR400 will accept lugs or

bus bars. Unprotected bulk connections are double, ¼"-20 (M6) studs with 5/8" centers. The

maximum tongue width for bulk connections is 0.67". Select a wire or bus bar size for the bulk

outputs according to the current rating as shown in Table 5. Choose lugs according to section

Table 6. The polarity of the system is universal; therefore the polarity of the output is determined

by the system grounding. See section 2.3.2 for more detail. The THR4 is capable of delivering a

max of 200 amps total, 100 amps per side. The THR400 is capable of delivering a max of 400

amps total (300 amps continuous), 200 amps per side.

2.3.2 DC

Reference Ground

The Lambda Power system is a fully floating system. This means that neither the positive nor the

negative are tied to the chassis or an earth ground. An external reference or earth ground may

be connected to either the positive output or the negative output depending the desired output

polarity. As always follow your company's guidelines for sizing and attaching a reference ground.

2.3.3

Wire

Sizing

There are two main considerations for sizing DC wire, ampacity and voltage drop. Ampacity

refers to a safe current carrying level as specified by non-profit organizations such as

Underwriters Laboratories and the National Fire Prevention Association, which publishes the

National Electric Code. Voltage drop is simply the amount of voltage loss in a length of wire

due to ohmic resistance of the conductor. DC wire may be sized for either ampacity or voltage

drop depending on branch load loop length and conductor heating. In general, ampacity

considerations will drive wire selection for short loop lengths (less than 50 feet) and voltage

drop will drive wire selection for long loop lengths (greater than 50 feet).

The National Electric Code table 310.16 provides ampacity values for various sizes, bundles, and

insulation temperature rated wire. ALWAYS

Table 5 below is a list of lug part numbers from Burndy that can be used for DC connections.

Wire type should be considered when determining the type of lug to use. These part numbers are

based on flex style cable. Follow your company practices when determining the exact lug

required. Systems requiring more than a 2 AWG (max 125 A) connection will need custom bus

bars. Note: ¼" holes will work on M6 studs.
