Basic Installation Procedures
AC Input Connections
To make a permanent connection to existing AC wiring:
1. Ensure AC and DC power sources are turned off.
2. Install the required circuit breaker in the AC distribution
panel supplying AC power to the unit. In a marine
installation, mount the required SPD or TVSS in the AC
distribution panel as well, according to marine electrical
codes or regulations.
3. Remove the wiring compartment cover by loosening the
captive nut panel screw and lifting the cover up and out
(Figure 5 ).
NOTE:
Use a screwdriver to loosen the captive nut panel screw.

4. Strip 10 mm off the ends of each of the wires (tin the
exposed copper wire with lead-free solder using a
soldering iron) in the AC cable (3+1G cable).
5. Remove the knockout and install the supplied ¾" bushing
on the AC input hole. Alternatively, you can install a ¾"
strain-relief device instead of the bushing.
6. Route the wires through the bushing (or strain relief
device).

2 Insert the wire fully into the open slot.
3 Lower the terminal lever to secure the
wire in the slot.
7. Locate the Neutral, Ground and Line terminals on the AC
input terminal labeled as L1, N, L2, and G respectively.
8. Connect each AC wire into its corresponding terminal on
the no-tool cage clamp terminal block.
9. Make sure that each AC wire is matched and connected to
the Neutral (N), Ground (G), and Line (L1 and L2)
connections.
10. If a strain-relief device was installed, tighten the strain
relief clamp to secure the wires.
11. Replace the wiring compartment cover onto the unit (using
a #2 Phillips torque screwdriver - see WARNING), if you
are not connecting other wires such as for the AC Output.
Otherwise, keep the AC compartment open and proceed
to the next step.
ELECTRICAL SHOCK HAZARD
Use a torque screwdriver to tighten the captive nut panel
screw to 5 in-lb (0.56 N-m) torque of force to ensure a proper
ground connection and a required tool access to the wiring
compartment.
Failure to follow these instructions can result in death,
serious injury, or equipment damage.
12. Connect the other end of the wires to the circuit breaker in
the AC distribution panel supplying AC power to the unit.
For possible wiring configurations into the vehicle's (or
vessel's) input AC distribution panel, see the various
figures starting on page 23.
NOTE: AC input hole - install a
bushing (supplied) or a strain-
relief device.
