Description
The generator voltage is unbalanced more than the value of
Volt unbal setpoint.
ECU alarm list is not empty. (Not available on MLG, MLT or
MTT units.)
Warning alarm in case of lost connection to IGL-RA15 mod-
ule. (Not available on MLG, MLT or MTT units.)
The period for servicing is set by the WrnMaintenance set-
point. The protection comes active if the running hours of the
engine reach this value.
Electrocution. Before connections are made to
the unit, verify the main circuit breaker and
battery disconnect switch are OFF. Failure to do
so will result in death or serious injury.
Electrocution. Never connect this unit to the electrical
system of any building unless a licensed electrician
has installed an approved transfer switch. Failure to
do so will result in death or serious injury.
The unit is equipped with connection lugs, located behind
a door below the controller face. The lugs provide
connection points for attachment of external loads to the
generator. A large decal on the inside of the connection
lug door details the proper connections for selected
voltages.
1. See Figure 3-9. To make the connections, run the
power cables through the circular plastic bushing
(A).
NOTE: DO NOT make any connections directly to the
lugs without routing the cables through this bushing. The
lug door is equipped with safety interlock switches that
will automatically trip the main circuit breaker and disable
the voltage regulator when the lug door is opened.
2. Use a hex-wrench to tighten the cable connections
(B).
NEVER attempt to disable or modify the lug door safety
switches.
A ground connection is located next to the connection
lugs. The unit MUST be connected to a good earthen
ground for proper operating safety. INSTALLATION
SHOULD BE IN COMPLIANCE WITH THE NATIONAL
ELECTRICAL CODE (NEC), STATE, AND LOCAL
REGULATIONS.
