Ground (earth) wire must be connected to the chassis of the AC power system using the ground
connection of the AC input terminal block. The mains source must have a current rating equal to or
greater than the input fuses and the input wiring must be sized to satisfy the applicable electrical
codes.
The AC input terminal strip accommodates a #6 ring or spade lug. The use of sleeved ring lugs (12/10-
6 Yellow sleeve lug) or compressed cable lug is recommended.
Following input terminal lugs are included in i/iX ship kit:

The input power cord must be large enough to handle the input current of the power source and must
conform to local electrical codes. Route the AC input wiring throught the AC input safety cover strain
relief before attaching to the AC input terminal block. Note that all wires must be sized to
accommodate the worst-case maximum current that may occur under low line conditions. Local
electrical codes may also require different wire types and sizes.
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
For cable lengths less than 25 feet, the following wire gauge AC line input cord is recommended:

Note: Always install supplied safety cover (P/N 6005-214-1) on AC input terminal block after
connecting input wiring and before applying power.
CAUTION: Capacitors in the power source may hold a hazardous electrical charge even if
the power source has been disconnected from the mains supply. Allow capacitors to
discharge to a safe voltage before touching exposed pins of mains supply connectors.
Power modules need at least 5 minutes to discharge to safe levels before they can be
removed.
