Chapter 4 Power Supply Installation

Installing a DC Power Supply

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003

Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 20 A. Statement 1005

Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement 1022

Warning Hazardous voltage or energy may be present on power terminals. Always replace cover when terminals are not in service. Be sure uninsulated conductors are not accessible when cover is in place. Statement 1086

Note The grounding architecture of this product is DC-isolated (DC-I).

Equipment That You Need

Ratcheting torque screwdriver with a number-2 Phillips head that exerts up to 15 pound-force inches (lbf-in.) of pressure.

Panduit crimping tool with optional controlled-cycle mechanism (model CT-720, CT-920, CT-920CH, CT-930, or CT-940CH).

Wire-stripping tools.

12-gauge copper ground wire (insulated or not) for the single-ground connection.

8-gauge copper ground wire (insulated or not) for the dual-ground connection.

Ground lug screw (not included in the accessory kit) and ring lug connector in the switch accessory kit. For a dual-ground connection, also use the dual-ground adapter and dual lug connector.

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
