Rack Mounting

Use four screws to attach the PT switch to a standard rack.

NOTE

Two additional rack-mount ears can be ordered as an option. Use

them to secure the rear of the chassis in

high-vibration

environments.

Wiring Requirements

WARNING

Safety First!

Be sure to disconnect the power cord before installing and/or

wiring your Moxa PowerTrans Switch.

Calculate the maximum possible current in each power wire and

common wire. Observe all electrical codes dictating the

maximum current allowable for each wire size.

If the current goes above the maximum ratings, the wiring could

overheat, causing serious damage to your equipment.

Grounding Moxa PowerTrans Switch

Grounding and wire routing help limit the effects of noise due to

electromagnetic interference (EMI). Run the ground connection from the

ground screw to the grounding surface prior to connecting devices.

Wiring the Power Inputs

The PT series of switches supports dual redundant power supplies:

“Power Supply 1 (PWR1)” and “Power Supply 2 (PWR2)”. The connections

for PWR1, PWR2 and the RELAY are located on the terminal block. The

front view of the terminal block connectors are shown below.

Wiring the Relay Contact

Each PT switch has one relay output. Refer to the next section for detailed

instructions on how to connect the wires to the terminal block connector,

and how to attach the terminal block connector to the terminal block

receptor.

FAULT: The relay contact of the 10-pin terminal block connector are used

to detect user-configured events. The two wires attached to the RELAY

contacts form an open circuit when a user-configured event is triggered.

If a user-configured event does not occur, the RELAY circuit will be closed.

Wiring the Redundant Power Inputs

Each PT switch has two sets of power inputs: power input 1 and power

input 2.

STEP 1: Insert the dual set positive/negative DC wires into PWR1 and

PWR2 terminals (+ →pins 1, 9; - →pins 2, 10). Or insert the L/N AC

wires into PWR1 and PWR2 terminals (L →pin 1, 9; N →pin 2,10)

STEP 2: To keep the DC or AC wires from pulling loose, use a screwdriver

to tighten the wire-clamp screws on the front of the terminal block

connector.

Note 1: The PT switch with dual power supplies uses PWR2 as the first

priority power input by default.

Note 2: For dielectric strength (HIPOT) test, users must remove the

metal jumper located on terminals 3, 4, and 7, 8 of the terminal block to

avoid damage.
