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 a

ll 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.
