(12/10-6 Yellow sleeve lug) or compressed cable lug is recommended.
Following input terminal lugs are included in i/iX ship kit:
Use CI P/N Description Qty supplied For use with:
INPUT (TB2) FS2004 Ring Lug 12/10-6 3 115V AC input
INPUT (TB2) FS2006 Ring Lug 16/14-6 3 230V AC input
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:
AC Line Voltage Wire Gauge Metric Diameter Nearest Metric Equivalent
115 V AWG10 2.59 mm 6 mm2
230 V AWG14 1.63 mm 2.5 mm2
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 mod
ules need at least 5 minutes to discharge to safe levels before they can be
removed.

3.6 Output Connections
3.6.1 Output Wiring
The output terminal blocks for each unit are located at the rear of the unit. Output connections are
made to the terminal block labeled OUTPUT. For a two-box system, the output terminals from both the
master and auxiliary units must be connected together. See Figure 3-7.
The external sense inputs allow the power system output voltages to be monitored directly at the load
and must be connected at output terminal connector. The external sense wires should be run as a
twisted pair for short lengths. Sense leads over three (3) feet long should be run as a twisted shielded
pair.
Note: The output of the power source is isolated from the input line and floating with respect
to chassis ground. If needed, either side (HI or LO) may be grounded.
The output power cables must be large enough to prevent a total voltage drop exceeding 3 % of the
programmed output voltage between the power source and the load. Note that wires must be sized to
accommodate the maximum current that is available. This may be a function of the voltage range.
Always use the current available on the low voltage range to size the wires.
For cable lengths less than 25 feet, the following wire gauge is recommended:
Wire Gauge Metric Diameter Nearest Metric Equivalent
AWG12 2.05 mm 4 mm2
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

3.6.2 Output Terminal Block - OUTPUT
Each chassis has a single AC output terminal block. The output terminal block must be covered using
the supplied AC Output safety cover. The terminal blocks are large enough to accommodate required
wire gauge sizes. The terminal block is located in the upper left corner on the rear panel of the unit.
(Looking from the back). Connector type is Magnum, A307104R50.
The AC output 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 for the load carrying output wiring is
recommended.
Following output terminal lugs are included in i/iX ship kit:
Use CI P/N Description Qty supplied For use with:
OUTPUT (TB2) FS2004 Ring Lug 12/10-6 2 Output Hi, Output Lo
SENSE (TB2) FS2002 Ring Lug 22/18-6 2 Sense Hi, Sense Lo
Multi-chassis configurations have two output terminal blocks, one on the master chassis and one of
the auxiliary chassis.
For operation as a multi-chassis system, the outputs of all chassis must be connected together using
the additional terminal blocks provided in the ship kit. Keep the wire lengths between each chassis
and this common terminal block the same.
See Figure 3-7 for multi-chassis output wiring diagram.
