Moxa PT-508-MM-SC-24 [7/15] Attention

- 7 -

Please read and follow these important guidelines:

• Use separate paths to route wiring for power and devices. If power

wiring and device wiring paths must cross, make sure the wires are

perpendicular at the intersection point.

NOTE: Do not run signal or communications wiring and power wiring

in the same wire conduit. To avoid interference, wires with different

signal characteristics should be routed separately.

• You can use the type of signal transmitted through a wire to

determine which wires should be kept separate. As a rule of thumb,

wiring with similar electrical characteristics can be bundled together.

• Keep input wiring and output wiring separate.

• It is strongly advised that you label wiring to all devices in the system.

Grounding the PowerTrans Switch

Grounding and wire routing help limit the effects of noise due to

electromagnetic interference (EMI). Run the ground wire from the

grounding screw to the grounding surface prior to connecting devices.

ATTENTION

Before

powering on the PT-508 (24/48 VDC models), make sure

that the g

rounding cable is secured between the

grounding screw

and ground for surge protection on the

terminal block.

Ground for

surge protection is on terminal 3 of the terminal block as shown

below.

ATTENTION

This product is to be mounted to a well

-grounded mounting

surface, such as a metal panel.

ATTENTION

For dielectric strength (HIPOT) test, users must remove the

grounding cable secured between the grounding

screw and

ground for surge protection located at terminal 3 of the terminal

block to avoid damage.
