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 Rel a y Conta ct

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.

t power applied

The relay contact is used to d etect user-config ured 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
below:

- 4 -

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 ins ert 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 screw driver
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 switche s fe at u r e au t o-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 1000Ba seTX Cabling

The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbps Ethernet
communications over distances of up t o 100 meters usi n g al l 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 req ui r ed for proper Gigabit Ethernet operatio n. 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-build ing comm unications.

• 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 inductiv e
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.

The PT-7528 seri es has one USB con sole port ( type B connecto r), 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 releas e the Reset button to
load factory default s ettings.

Rack Mounting Ins tr uctions

NOTE

The rackmount ears can be attached to the front or rear of the
PT-7528 switch.

• 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

before touching it. The location should only be accessible with a key
or through a security identity system.

1. Elevated Operatin g Am bient: 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 circui t and the ef fect that
overloading of the circuits might have on overcurrent p rotection 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).

Power Connection Warning

You should always connect both power supplies when using this device,
and disconnect both power supplies when this device is not in use. If only
one power supply is connected, you could receive a hazardous electric
shock by touching the unconnected terminals of the other power supply.

All power connection wiring must be done by a qualified electrician and
follow the National Electrical Code, ANSI/NFPA 70, and Canadian
Electrical Code, Part I, CSA C22.1. An IEC certified or UL listed
single-phase type circuit-breaker, rated for a maximum of 20 A, should
be installed between main ci rcuit and the device.
