Inverter To Battery Bank Wiring - Magnum Energy MMS Series Owner's Manual

Info: To ensure the best performance from your inverter
system, do not use old or untested batteries. Batteries
should be of the same size, type, rating, and age.
CAUTION: Install batteries in a well ventilated area.
Batteries can produce explosive gasses. For compartment
or enclosure installations, always vent batteries to the
outside.

2.3.1 Inverter to Battery Bank Wiring

WARNING: Ensure all sources of DC power (i.e.,
batteries) and AC power (shorepower or AC generator)
are de-energized (i.e., breakers opened, fuses removed)
before proceeding.
CAUTION: The inverter is NOT reverse polarity protected.
If this happens, the inverter will be damaged and will
not be covered under warranty.
DC wires from the batteries to the inverter, verify the
correct battery voltage and polarity using a voltmeter.
If the positive terminal of the battery is connected to
the negative terminal of the inverter and vice versa,
severe damage will result. If necessary, color code the
cables with colored tape or heat shrink tubing; RED for
positive (+), and BLACK for negative (–) to avoid polarity
confusion.
Info: The DC overcurrent device (i.e., fuse or circuit
breaker) must be placed in the positive (RED) DC cable
line between the inverter's positive DC terminal and the
battery's positive terminal (RED); as close to the battery
as possible.
DC Ground Wire
Route an appropriately sized DC grounding wire (GREEN or bare
wire) from the inverter's DC Ground Terminal (see Figure 1-3, Item
11) to a dedicated system ground. Recommended tightening torque
is 45 in-lbs (5.2 N m).
DC Negative Wire
Route an appropriately sized DC negative wire (BLACK) from the
negative terminal of the last battery string to the inverter's negative
terminal (see Figure 2-8 for reference).
Battery Temperature Sensor
Connect the RJ11 connector end of the BTS to the ACCESSORY PORT
(see Figure 1-4, Item 15) on the inverter. Connect the other end of
the BTS to the negative terminal of the last battery string (in same
place as the DC negative wire above—see Figure 2-8); refer to Figure
2-6 for the correct hardware placement.
