4. Electrical Installation

4.1 General

Danger: Turn off electrical power before servicing. Contact with live electric components can

cause shock or death.

Notice: If any of the original wire supplied with the system must be replaced, use similar wire

of the same temperature rating. Otherwise, insulation may melt or degrade, exposing bare

wire.

All wiring must be in compliance with the local codes or in their absence, the National Electric Code,

NFPA70. All wiring should be appropriate Class 1 wiring as follows: installed in rigid metal conduit,

intermediate metal conduit, rigid non-metallic conduit, electrical metallic tubing, or be otherwise suitably

protected from physical damage.

RSIB models operate at different voltages, so it’s important to pay attention to the wiring details.

RSIB 300 operates at 1x120VAC while all other models can operate at 3x208-230VAC or

3x440-480VAC.
