Wiring Requirements
WARNING
Safety First!
•
Be sure to disconnect the power cord bef
ore 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 Inputs
The PT-7528 switches support 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-7528 switch provides two types of relay output, at the user’s
option. See below 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.

The relay contact is used to detect user-configured events. Two wires are
attached to the relay pins. The PT-7528 provides normal open and normal
closed circuits at the user’s option. For pin definitions, refer to the table

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, 7; – pins 3, 9), or insert the L/N AC wires
into PWR1 and PWR2 terminals (L pins 1, 7; N pins 3, 9).
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.
Ethernet Ports
Fast Ethernet RJ45 Twisted-Pair Cabling
PT-7528 series switches are equipped with several 10/100BaseTX ports
for connecting to standard CAT-5 STP cables with RJ45 male connectors.
PT-7528 series switches feature auto-negotiation, auto-polarity, and
auto-crossover functions. For high EMC environment applications, we
suggest using shielded twisted-pair cables to avoid EMC interference to
retain compliance with the IEEE 1613 standard.
Gigabit Ethernet 1000BaseTX Cabling
The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbps Ethernet
communications over distances of up to 100 meters using all 4 pairs in
category 5 (or higher) balanced unshielded twisted-pair cabling. For
wiring guidelines, system designers and integrators should refer to the
Telecommunications Industry Association (TIA) TIA/EIA-568-A wiring
standard that characterizes the minimum cabling performance
specifications required for proper Gigabit Ethernet operation. To ensure
reliable, error-free data communication, new and pre-existing
communication paths should be checked for TIA/EIA-568-A compliance.
•Data cable lengths should be as short as possible, ideally limited to 3
m (10 ft) in length. Copper data cables should not be used for
inter-building communications.
•Power and data cables should not be run in parallel for long distances,
and should be installed in separate conduits. Power and data cables
should intersect at 90° angles when necessary to reduce inductive
coupling.
•Optionally, shielded/screened cabling can be used. The cable shield
should be grounded at one single point to avoid the generation of
ground loops.

USB Console Connection
The PT-7528 series has one USB console port (type B connector), located
on the top panel. Use the USB cable (provided in the product package) to
connect the PT-7528’s console port to your PC’s USB port and install the
USB driver (available in the software CD) on your PC. You may then use
a console terminal program, such as Moxa PComm Terminal Emulator, to
access the PT-7528’s console configuration utility.

USB Storage Connection
The PT-7528 series has one USB storage port (type A connector) on the
front panel. Use Moxa’s ABC-02-USB-T automatic backup configurator to
connect the PT-7528’s USB storage port for configuration backup,
firmware upgrade, or system log file backup.
ABC-02-USB Installation
Plug the ABC-02-USB into the USB storage port of the Moxa PT-7528
series. We suggest attaching the ABC-02-USB to a wall with an M4 screw.

The Reset Button
Depress the Reset button for five continuous seconds to load the factory
default settings. Use a pointed object, such as a straightened paper clip or
toothpick, to depress the Reset button. When you do so, the STATE LED
will start to blink about once per second. Continue to depress the STATE
LED until it begins blinking more rapidly; this indicates that the button has
been depressed for five seconds and you can release the Reset button to
load factory default settings.
NOTE
DO NOT power off the switch when loading default settings.

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.
3. Mechanical Loading: Mounting of the equipment on 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 Grounding: Reliable grounding 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).
NOTE
The rackmount ears can be attached to the front or rear of the
PT-7528 switch.
