Aux DC Output (AUX)
The Aux Output port provides auxiliary DC power from the battery
for small loads not exceeding 20 amps (e.g., an interior lamp,
backup camera, etc.). Wh12V is applied to the ignition
(ICS) input, an internal relay closes and provides battery voltage
(up to 20 amps) on the auxiliary (AUX) DC output.
Info:
The MMSA inverter/charger must be connected to
the battery for the aux DC output to be available.
Ignition Control Switch (ICS)
With an ignition switch (a +12 VDC signal) wired to this port, the
inverter automatically turns on (in turn disabling the inverter’s ON/
OFF switch and the remote’s ON/OFF button—if connected). Refer
to the Switch 2 section on
pages 25-26 for information on setting up
an ignition control switch for your system, and for other conditions
and considerations that affect this feature.
Ground Control Switch (GCS)
With a ground switch wired to this port, you can automatically turn
on the MMSA1012 inverter/charger (in turn disabling the inverter’s
ON/OFF switch and the remote’s ON/OFF button—if connected).
Refer to the Switch 3 section on page 26 for information on setting
up a ground control switch for your system, and for other conditions
and considerations that affect this feature.
2.5 Remotes and Connections
2.5.1 Remotes and Remote Settings
Sensata Technologies offers several remotes that let you monitor
the inverter/charger and enable you to switch the inverter on/off
from a convenient location. Using cables with RJ11 connectors
(included with purchase of remote), the remotes easily connect to
either of the inverter’s Remote ports (Figure 2-6).
Note:
Only one remote control (e.g., MM-R, MM-RC, ME-RC, or ME-
ARC) can be connected to the inverter at any time. The MM-C monitor
is the only remote that can be connected to the inverter with one of the
remote controls.
MM-R
– Provides three LED indicators (INVERT, AC IN, FAULT) for
inverter status and includes a remote ON/OFF power switch; comes
with a 25’ cable.
MM-C
(monitor only) – Provides three LED indicators (BULK,
ABSORB, FLOAT) for battery and charger status; comes with a 25’
cable.
MM-RC
– Provides six LED indicators for inverter and battery charger
statuses, and includes a remote ON/OFF power switch; comes with
a 25’ cable.
