Customer Communication Module (CCM) for Diesel Engines Caterpillar

Environmental

• The ambient operating temperature range is from -40° to 70°C (-40° to 158°F).

• The storage temperature is from -40° to 85°C (-40° to 185°F).

• The unit must be protected from direct contact with liquids. If sealing of the unit is required, the CCM must be in a water tight enclosure.

• The CCM weighs 0.75 kg (1.65 lb).

Mounting

The CCM can be located on a desk or on a shelf. The rubber feet on the bottom of the CCM can be removed for mounting to a panel.

Note: Do not mount the CCM on the engine or within the engine mounted instrument panel. The CCM is not designed for direct engine mounting.

Internal Battery

The CCM contains a battery that supplies power for internal memory whenever the CCM is turned off. Refer to the Operation and Maintenance Manual, "Battery - Replace".

Power Supply

• The requirements for battery voltage are 15 to 45 volts DC (24 or 32 volts DC nominal power).

• The +/-B power dissipation is approximately 3.0 watts at 24 volts.

• The current drawn by the CCM is 0.11 amps at 12 volts and 0.13 amps at 36 volts.

• Multiple engines must share a common ground (-B).

• Multiple engines must use diodes to prevent power sharing between units.
