Power Inverter (Option)

A 12 Vdc to 120 Vac inverter is available as an option for
TriPac. The inverter is normally connected directly to the truck
batteries.

Inverter features will vary, depending upon the brand and
model used. Typically, when the inverter detects an AC load, it
automatically turns on and converts DC to AC power for
onboard 120 Vac devices. If the TriPac is enabled and the
inverter draws truck battery voltage down below the voltage
limit established for the installation, the TriPac will start and
attempt to recharge the truck batteries back to the level
specified. If the TriPac is not enabled, the inverter could drain
the truck batteries below the level required to start the truck or
the TriPac.

Manufacturer’s instructions for the optional inverter are
provided separately. It is important to read and follow those
instructions for proper use of the inverter.

Inverter Operation Wa rn ing s

DANGER: Do not use an inverter in life support or
health care applications where a malfunction or
failure of the inverter could cause failure of a life
support device or medical equipment or significantly
alter the performance of that equipment.

DANGER: Potentially lethal voltages exist within the
inverter as long as the battery supply is connected.
During any service work, the battery supply should be
disconnected.

DANGER: Do not connect or disconnect batteries
while the inverter is operating from the battery
supply. Dangerous arcing may result.
