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 terperature 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.
IPVB models operate at different voltages, please pay
attention to the wiring details. IPVB 300 operates at
1x120VAC while all other models can operate at 3x208-230
VAC or 3x440-480VAC. This is indicated by the terminal wire
configuration in the motor junction box. See Section 4.3.
