current that is available. This may be a function of the voltage range and phase mode on some
RS models. If the RS has more than one output voltage range, size the wires for the lowest
available voltage range as the currents will be highest in that range.

Cable lengths must not exceed twenty-five (25) feet. For lengths greater than 25 feet, calculate
the voltage drop from the following formula:

2 X DISTANCE X CABLE RESISTANCE PER FT. X CURRENT = VOLT DROP

* Data shown for use of high temperature (100° C) rated stranded copper wire, unbundled and
not installed in conduit. Adjust wire gauge for Aluminum wire type.

Note: Use high temperature rated wire. Always consult the National Electrical Code

and/or local code regulations for proper rating and size of wire cabling prior to
installation.
