Wiring Requirements
Be sure to disconnect the power cord bef
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
