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.
