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 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.

Rack Mounting Instructions
1. Elevated Operating Ambient:If installed in a closed or multi-unit
rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
2. Reduced Air Flow:Installation of the equipment in a rack should
be such that the amount of air flow required for safe operation of
the equipment is not compromised.

- 9 -
3. Mechanical Loading:Mounting of the equipment in the rack
should be such that a hazardous condition is not achieved due to
uneven mechanical loading.
4. Circuit Overloading:Consideration should be given to the
connection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent
protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this
concern.
5. Reliable Earthing:Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply
connections other than direct connections to the branch circuit (e.g.
use of power strips).
Restricted Access Locations
•This equipment is intended to be used in Restricted
Access Locations, such as a computer room, with
access limited to SERVICE PERSONAL or USERS who
have been instructed on how to handle the metal
chassis of
equipment that is so hot that special protection may be needed
before touching it. The location should only be accessible with a
key
or through a security identity system.
•External metal parts of this equipment are extremely hot!! Before
touching the equipment, you must take special precautions to
protect your hands and body from serious injury.
ATTENTION
1.
This device is only for indoor use and Pollution degree 2.
2.
Conductors rated to withstand at least 105
°C must be used
for the Power Supply Terminal.
3.
When wiring the relay contact, digital input and power
inputs, we suggest using the cable type - AWG (American
Wire Gauge) 16-24 and the corresponding pin type cable
terminals. The connector must be able to withstand torque
at maximum 5 pound-inches.
4.
The equipment has a separate protective earthing terminal
on the chassis that must be permanently connected to
earth ground to adequately ground the chassis and protect
the operator from electrical hazards. To avoid risks of
electric shock, do not replace or remove the protective
conductor.
5.
The IP rating is not part of the safety certification.
6.
This device must be installed within a suitable enclosure.
7.
The cable that is connected to the field wiring terminals
must be able to withstand at least 75°C.
Responsible Risk
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired. The manufacture is not responsible for any accident caused
by the scenario mentioned above.
