INSTALLATION
MAIN CIRCUIT CABLING
Cables which connect to the power cell should
be routed to avoid interference with sharp edges
and moving parts. Minimum bending radius for
the type of cable used should be observed.
Power cables should be braced and/or laced to
withstand short-circuit forces wherever such
cables are unsupported. Power cables should be
adequately sized to
continuous current and should have an adequate
voltage rating.
The OEM should perform a temperature rise test
on the completed controller to verify compliance
with the temperature rise requirements of NEMA
ICS3 Part 2.
It is recommended that a cable size of at least
4/0 AWG be used throughout the power circuit
for continuous ratings up to 360A. It should be
noted, however, that the maximum obtainable
continuous current rating of the controller might
be less than 360A in some cases. This is due to
a number of factors that have an influence on
temperature rise, including:
- Ventilation provided (enclosure type)
- Number of controllers stacked vertically
- Controller position within a stacking
arrangement
