Wiring Requirements
• 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 the 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 Input (110/220 VDC/VAC
models)
The PT-7710 (110/220
VDC/VAC models) has one
set of power inputs,
referred to as power input
1. The front view of the
terminal block connector is
shown here.
STEP 1: Insert the L/N AC wires into the PWR1 terminals (L pin 1, N
pin 2).
STEP 2: To keep the AC wires from pulling loose, use a screwdriver to
tighten the wire-clamp screws on the front of the terminal block.
Wiring the Redundant Power Inputs (12/24/48
VDC models)
The PT-7710 (12/24/48
VDC models) has two sets
of power inputs, referre
to as power input 1 and
power input 2. The front
view of the terminal block
connector is shown here.
STEP 1: Insert the dual set positive/negative DC wires into PWR1 and
PWR2 terminals (+ pins 1, 9; - pins 2, 10).
STEP 2: To keep the DC wires from pulling loose, use a screwdriver to
tighten the wire-clamp screws on the front of the terminal block.
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
term
terminal block connector to the terminal block receptor.
FAULT: The RELAY contacts 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.

*Slot 2 (M2) is mainly used for Gigabit modules. If 100BaseFX modules
are used in Slot 2 (M2), the modules will not support “Far End Fault”. The
Link/ACT LED indicator will stay at “Green (ON)” status when Fiber TX
cable is unplugged.
