Unpacking and Installing the Controller

Grounding the Chassis

Follow the grounding procedures at your site and observe these warnings:

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Caution We recommend grounding the chassis, even if the rack is already grounded.

Caution All power supplies must be grounded. The receptacles of the AC power cables used to provide power to the chassis must be the grounding type, and the grounding conductors should connect to protective earth ground at the service equipment.

Note The grounding lug must be NRTL listed and compatible with copper conductors. Only copper conductors (wires) must be used and the copper conductor must comply with National Electrical Code (NEC) for capacity.

Follow these steps to install the grounding lug on the controller. Make sure to follow any grounding requirements at your site.

Step 1 Strip the ground wire to 0.5 inch (12.7 mm) ± 0.02 inch (0.5 mm) (see Figure 7). Stripping more than the recommended amount of wire can leave exposed wire from the connector.

Step 2 Slide the open end of the ground lug over the exposed area of the wire.

Step 3 Using a Panduit crimping tool, crimp the ground lug to the wire.

Step 4 Remove the grounding bracket from the back of the controller by unscrewing the two phillips flat-head screws holding on the bracket (see Figure 8).
