µ-Dimension 12/400N Owner's Manual - page 3
3.05.3 U.L. codes require the use of an
auxiliary fuse to be installed within 18 inches from
the battery.
3.05.4 NOTE: Using smaller input cable
or longer length will greatly degrade the inverter
peak performance.
NOTE FOR VEHICLE INSTALLATION: Do not
use the vehicle chassis as the negative return in
place of a return cable. Use the same size cable
as the positive connection and run directly to the
battery/alternator.
3.05.5 Install the wires on the battery,
inverter and then fuse holder. Make sure that
tight, clean connections are made. Use care not
to touch the positive and negative wires together.
This will result in a violent spark and could result
in exploding batteries and fire.
3.05.6
CAUTION: Connecting the inverter
incorrectly to the battery with the polarity re-
versed will cause damage that is not covered
under warranty!
3.05.7 Connect the White wire to the
negative (-) post on the battery. Connect the Red
wire to the fuse that is connected to the positive
(+) post on the battery. A mounting spark may
result when connecting the battery wire.
3.06 Remote ON/OFF Switch - Fig. 1
3.06.1 If a remote switch is not used, no
connection is necessary to the violet wire.
NOTE: Connecting the violet wire to chassis
ground will cause damage not covered un-
der warranty!
3.06.2 All material used for the remote
switch should be UL listed and installed per code.
3.06.3 The remote switch should be single
pole, single throw with a 5 Amp rating. The wire
used should be at least 18 gauge.
3.06.4 The switch should be mounted at
a convenient location with approved strain relief.
3.06.5 The remote switch should be con-
nected to the violet wire extending from the unit,

external AC power source is applied to the inverter’s
AC outlet or its hardwire output.
CAUTION: Be sure the inverter's circuit breaker or
fuse are turned “OFF” during installation.
NOTE: All wiring must follow the National Electric
Code, Provincial or other codes in effect at the
time of installation, regardless of suggestions in
this manual. All wires should be copper conduc-
tors.
3.03 Mounting
3.03.1 Locate a suitable, secure flat mount-
ing surface as close to the battery as possible
without being in the same airtight compartment.
The maximum recommended distance between
the mounting location and the battery is 20 feet.
3.03.2 The location should have adequate
ventilation and clearance to maintain room tem-
perature while the unit is operating. At least 1/2
inch of clearance is required on all sides.
3.03.3 Secure the unit with #8 or larger
screws or bolts in the mounting slots on the
flanges of the chassis.
3.04 Chassis Bonding Lug - FIG. 1
3.04.1 Connect a #8 gauge or greater cop-
per wire between the bonding lug on the inverter
and the earth grounding system or the vehicle
chassis.
3.05 Battery Wiring - FIG. 1
3.05.1
CAUTION: Make sure that hydrogen
gas does not accumulate near the battery by
keeping the area well ventilated. A spark may
result when connecting the battery wiring due to
an initial charging of the internal input capacitor.
3.05.2 The recommended stranded copper
wire between the battery and the inverter and the
necessary line fuse are indicated:
Battery to Inverter Distance (feet)
