Installation
- 24 - IQ SERIES OWNERS MANUAL
9. Install the in-line fuse. Install an in line fuse in the red, positive DC input cable between the
battery and inverter, within 18 in. of the battery or DC wiring bus system. Be sure to mount fuse
in easily accessible location for replacement. It is also “good practice” to note on the inverter to
check the fuse condition before involving any troubleshooting procedure.
10. Connect Bonding Lug. ( see #21 ). Use AWG No.8 or larger copper conductor to connect chassis
bonding lug to the vehicle chassis and/or earth ground.
11. Do not connect the inverter to the battery at this time. Final battery connections will be made
after all installation issues have been inspected.
3.5 AC Wiring Installation Procedure
1. Remove the front cover of the inverter exposing the AC wiring compartment. Identify location of
AC wiring terminal block (see item 2.19).
Note: AC input source branch rated overcurrent protection is to be provided by others to
comply with the National Electric Code, NFPA 70.
2. Insert the AC line (input) and load (output) wires through the appropriate strain reliefs into the AC
wiring compartment, and tighten the strain relief with a screwdriver.
3. Connect the AC output wire to the appropriate Hot, Neutral, and Ground terminals inside the AC
wiring compartment using suitable wire terminators such as crimped spade or ring terminals.
Torque terminal strip screws to 16 inch pounds.
4. Connect AC Input(s) (IQC Models only). Connect one 30 amp AC input circuit to AC1. If desired
connect an additional 30 amp AC input circuit to AC2. If using two AC input circuits they must
be in-phase (zero volts between AC1 hot and AC2 hot). The transfer relays will be
destroyed if AC1 and AC2 are out-of-phase. Connect input wires to the appropriate Hot,
Neutral, and Ground terminals for AC1 and AC2. Torque terminal strip screws to 16 inch
pounds..Replace the AC wiring compartment cover.
NOTE: If only a single 30 amp supply source will be used, it is only necessary to connect AC1
input (no connection to AC2) to a single branch-rated circuit breaker in the main AC distribution
panel(from shore/utility power or form a 10kW or larger generator). If two 30 amp supply circuits
are to be used, connect AC1 and ACI to two separate 30 amp branch-rated AC circuit breakers in
the main AC input distribution panel. See Section 5.2, AC Power Transfer Switch for more details.
5. Verify Installation. Verify all connections are tight and secure for maximum safety and
performance.
3.6 Remote Monitor and Control Panel Installation
Unpacking the Remote Monitor/Control Panel
Inspect the shipping container and equipment for loose, damaged, or missing parts. The remote
panel includes a 20-ft. interconnecting cable. If any damage is found, immediately notify the
freight carrier.
Steps
1. Locate a suitable place to install the remote panel such as a flat surface near the power
control/distribution panel or driver’s compartment. The mounting surface should have sufficient
space to accommodate the remote panel's depth and cable routing. Cut surface material large
enough to accommodate the remote control box leaving sufficient surface material to attach panel
with #8 mounting screws.
2. Route the 20-ft. interface cable from the remote panel mounting area to the inverter being careful
to avoid unprotected sharp corners or moving parts.
