6. Strip ½" (13 mm) to ¾" (19 mm) of insulation from each
cable end that will be connected to the inverter cable. The
amount stripped off will depend on the terminals chosen.
7. Attach the cable ring lug that will join the cable to the inverter
DC terminal. Cover the lug stem with heat shrink insulation
(see
Step 6: Connecting the DC Cables
) to ensure that the
lug does not touch the enclosure.
8. Install a fuse and fuse holder in the cable that will be used for
the positive side of the DC circuit. The fuse must:
a. be as close to the battery positive terminal as possible
b. be rated for DC circuits
c. have an Ampere Interrupting Capacity (AIC) that
exceeds the short-circuit current available from the
battery (that is, Class T fuse)
9. To prevent sparking when making the connection, ensure
the disconnect/battery selector switch is off.
10. Route the positive cable through the left side strain relief
clamp and attach the cable lug on the positive cable to the
positive DC terminal on the inverter.
11. Fasten the DC terminal nut (set aside earlier) to the terminal
bolt. Tighten the nut to a torque of 71–80 in-lb (8–9 N-m) of
force. Do not overtighten. Make the connection snug enough
so the cable lug does not move around on the DC terminal.
Center it through the DC knockout hole and do not let it
touch the edge. See
Step 6: Connecting the DC Cables on
WARNING
ELECTRICAL SHOCK HAZARD
l
Tighten the nuts on the DC terminals properly. Loose
connections cause excessive voltage drop and may cause
overheated wires and melted insulation.
l
Do not over-tighten the nut on the DC input terminals
because damage to the DC input terminals may result. Use a
torque screwdriver to tighten the nut to a maximum torque of
80 in-lb (9 N-m) of force.
Failure to follow these instructions can result in death, serious
injury, or equipment damage
.
NOTICE
REVERSE POLARITY
l
Check cable polarity at both the battery and the Freedom X
before making the final DC connection. Positive must be
connected to positive; negative must be connected to
negative. Check to see if the reverse polarity LED (see
) is not illuminated.
l
Reversing the positive and negative battery cables will blow
a fuse in the Freedom X and void your warranty.
Failure to follow these instructions can result in equipment
damage.
