STANDBY POWER CONNECTIONS
The Ranger® 250 GXT (AU) is suitable for temporary,
standby or emergency power using the engine manu-
facturerʼs recommended maintenance schedule.
Tha Ranger® 250 GXT (AU) can be permanently
installed as a standby power unit for 240 volt (60Hz).
Connections must be made by a licensed electrician
who can determine how the 240 VAC power can be
adapted to the particular installation and comply with
all applicable electrical codes. The following informa-
tion can be used as a guide by the electrician for most
applications.
1. Install an isolation switch between the power com-
pany meter and the premises disconnect. (The
Ranger® 250 GXT (AU) and the power company
supplies must not be connected together).
Switch rating must be the same or greater than the
customerʼs premises disconnect and service over cur-
rent protection.
2. Take necessary steps to assure load is limited to
the capacity of the Ranger® 250 GXT (AU).
Loading above the rated output will reduce output
voltage below the allowable -10% of rated voltage
which may damage appliances or other motor-dri-
ven equipment and may result in overheating of the
Ranger® 250 GXT (AU) engine.
