All Easy Change Connector blocks may be removed for convenient wiring. Loosen the set screws and gently pull
the plug away from the header. Insert wire into connection blocks and tighten as appropriate. After wiring the
Easy Change Connector block, insert into mating header and tighten the outer set screws to avoid disconnection
from vibration.

Output
12 VDC or 24 VDC set through Setup menu
Alarm Connections
Optional: Each alarm has a Common (C), Pass (closed when no alarm), and Fail
(closed when in alarm) connection
Remote Temp. Sensor
(93-RMTEMP01-A)
Optional: Connect to Remote Temp. Sensor (if purchased separately). Observe po-
larity. Place the non−conductive ring lug over any battery terminal to measure battery
temperature.
Remote Display
(93-RMDISP01-A)
Optional: Remove dirt cap and plug in remote display to unit. Use a standard
“straight” Cat−5E Ethernet cable (max 500 feet). Do not use a Cat−5E “cross−over”
cable. Remote display mirrors charger display including touch buttons.
Note: This port is not an Ethernet port. Do not connect to Ethernet type equipment to this
port.
IMC Series OPERATION
The IMC Series
™
is a completely automatic battery charging system. However, there are still a few parameters
that need to be configured by the user prior to use. If this is the first time using the system, the system will initial-
ly default into SETUP mode.
If the system has been previously setup, all the settings are recalled and the IMC Series
™
is automatically config-
ured to the previous settings.
Upon Power up (or the return of AC power, if missing), the IMC Series
™
will enter Bulk Mode (Lead Acid, Gel, or
AGM) or Equalize Mode (NiCAD), and stay in that mode for the duration set by Bulk Duration (Lead Acid, Gel, or
AGM) or Equalize Duration (NiCAD).
After the Bulk or Equalize Duration completes, the IMC Series
™
will enter Float Mode to maintain the batteries.
The IMC Series
™
will stay in Float Mode until the AC is removed or the battery voltage drops approximately 1.0
volts [12 Volt mode] or 2.0 volts [24 Volt mode] below Float voltage for approximately five minutes. After the time
delay, the IMC Series
™
will reenter the Bulk [Equalize] Mode for the duration set.
In order to achieve proper operation, the IMC must be connected to a suitable source of AC input power. When
using AC voltage input less than 95VAC, this battery charger will automatically reduce the DC output power by
turning off internal modules. The charger will display an error stating “REDUCED OUTPUT, CALL FOR SER-
VICE” until the AC voltage input has been reset and is above 95VAC.
