Rack Mounting
Use four screws to attach the PT switch to a standard rack.
Two additional rackmount ears can be ordered as an option. Use
them to secure the rear of the chassis in h igh
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 allow
If the current goes above the
maximum, 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 th e
ground screw to the grounding surface before 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 t he terminal block. The
front view of the terminal block connectors are shown below.
Wiring the Relay Contact
Each PT switch has one relay output. Ref er 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 termina l block conn ector is used
to detect user-configured events. The two wires attached to the RELAY
contacts form an open circuit when a user-conf igur ed event is tr igg ered.
If a user-configured event does not occur, the RELA Y 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 pins 1, 9; N pins 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.
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.
