Battery Charger Operation; A) Battery Capacity Selector - NewMar 12-1800IC Installation & Operation Manual

The panel face and mounting hole pattern have been designed for an exact fit within a
double-gang duplex outlet box. If preferred, it may be mounted directly to a bulkhead with
the four provided black-oxide wood screws. Note the cut-out dimensions specified in Figure 4
and take special care when making the cut-out, as the tolerances between the mounting
holes and rear-mounted circuit board are quite small.
The ICR-2 is supplied with 25 feet of cable. If additional length is required, contact the fac-
tory for an extension cable.
The inverter/charger is equipped with a factory-installed in-line connector assembly for the
remote panel. The connector has a "dummy" plug attached which enables all of the inverter/
charger functions when no remote panel is used. Remove and save this plug prior to attach-
ing the remote panel plug. (The dummy plug is required to restore proper functioning of the
unit if the remote panel must be disconnected for any reason in the future.)
The connector assembly is keyed to ensure correct orientation and uses a threaded collar to
secure the connection. Upon inserting the plug, tighten the collar until a "click" is felt, indi-
cating it has locked together properly.
Note: In order for the remote on-off switch to operate, the on-off switch on the inverter front
must be in the "ON" position.

BATTERY CHARGER OPERATION

Battery capacity and battery type selections must be set prior to applying AC to the charger.

A) Battery Capacity Selector

Part of the internal charger's "smart" charging algorithm involves calculating and delivering
the proper charge current in the latter stages partially based on the total amp-hour capacity
of the battery bank. This information is provided to the charger using a recessed selector
switch located on the right-hand side of the unit, near the rear. (Do not confuse this selector
with the Charger Output Selector located beside it—see section B, following).
Determine the total amp-hour capacity of the battery system which is being charged by the
inverter/charger. (If multiple banks are being charged, include all banks, not just the bank
which powers the inverter.) Then use a small flat-tip screwdriver to place the selector into
the correct position according to the following chart (this information is also duplicated on
the unit beside the selector port):
