PC operation may be adversely affected if the ground wire is shared with other

equipment or if the ground wire is attached to the metal structure of a building.

When using Expansion I/O Racks, the Racks must also be grounded to the

ground terminal. The same ground can be used for all Racks.

Screw (3.5 mm head with

self-raising pressure plate)

For grounding use 2 mm2 cable.

Be sure to keep the length of the

cable less than 20 meters.

Use crimp terminals for wiring. Do not connect bare stranded wires directly to

terminal blocks. Use M3.5 screws for tightening crimp terminals.

7 mm max.

Tighten the screws on the terminal block to a torque of 0.8 N

20 mm max.

WARNING Always attach crimp terminals to the ground lines to ensure proper connection.

Connecting loose wires can cause fires.

Caution

• Ground the Power Supply Units separately from other devices.

• After wiring the terminals check the terminal block to be sure it is firmly locked

in place.

Note If you suspect that grounding is the cause of operational errors, either discon-

nect the line ground and ground terminals and either ground the mounting plate

or try operating with no ground at all.
