Chapter 3 Power Supply and Fan Module Installation Installing a DC Power Supply • Ground lug screw and ring lug connector in the switch accessory kit. For a dual-ground connection, also use the dual-ground adaptor and dual lug connector from the DC power supply accessory kit. • Four leads of 14-gauge copper wire. • Four fork-type terminals from the DC power supply accessory kit. The terminals must be the proper size for M3 screws in a Dinkle DT-35-B25-style terminal block. Grounding the Switch 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 Follow the grounding procedure instructions, and use a UL-listed lug (included in the accessory kit). Follow these steps to install either a single-ground lug or a dual-ground lug on the switch. Make sure to follow any grounding requirements at your site. Step 1 Step 2 Use the ground lug screw and the lug ring for a single-ground connection. Use the dual-ground adaptor and dual-hole lug for a dual-ground connection. Strip the 12-gauge or 8-gauge ground wire to 0.5 inch (12.7 mm) ± 0.02 inch (0.5 mm) (Figure 3-8). Stripping more than the recommended amount of wire can leave exposed wire from the connector. Use 12-gauge copper ground wire for the single-ground connection. Use 8-gauge copper ground wire for the dual-ground connection. Figure 3-8 Stripping the Ground Wire 0.5 in. (12.7 mm) ± 0.02 in.

Step 2
Strip the 12-gauge or 8-gauge ground wire to 0.5 inch (12.7 mm) ± 0.02 inch (0.5 mm) (
Figure 3-8
).
Stripping more than the recommended amount of wire can leave exposed wire from the connector. Use
12-gauge copper ground wire for the single-ground connection. Use 8-gauge copper ground wire for the
dual-ground connection.
