CAUTION: IMPROPER LIFTING OF EQUIP-
MENT can result in personal injury and
equipment damage.
Use equipment of adequate capacity to lift the
unit.
If using lift forks to handle this unit, be sure the
lift forks are long enough to extend out of the
opposite side of the base.
Using lift forks too short will expose internal
components to damage should the tips of the lift
forks penetrate the bottom of unit.
RESTRICTED AIRFLOW can cause improp-
er cooling and unit damage; ENTRY OF
OBJECTS THROUGH TOP can damage unit.
Maintain at least 12 in (305 mm) of unre-
stricted space on all sides of the unit, and
keep air intakes on sides and outlet openings
on top free of obstructions.
Do not place tools, parts, etc. on top of unit.
Do not allow any objects to fall into top of unit.

DESCRIPTION
This unit is designed to provide an adjustable load dur-
ing output testing procedures for any single-phase 120
or 240 volts ac power source. This unit is equipped with
analog meters which provide simple and accurate read-
ings of voltage, amperage, and frequency.
Do not place any filtering device over the
intake air passages.
Warranty is void if any type of filtering device is
used.
This unit is equipped with rubber casters to allow easy
movement.
The service life and operating efficiency of this unit are
reduced when the unit is subjected to high levels of dust,
dirt, moisture, corrosive vapors, and extreme heat.

INTERCONNECTING CORD INSTALLATION
A. Cord Selection
It is necessary to obtain a proper 3-conductor cord for
making 120 volt and/or 240 volt input connections inside
the unit. Select a cord of adequate amperage capacity
and proper wire size for the rated amperage output of
the power source. In most applications, it should not be
necessary for the required cord length to exceed 25 ft
(7.6 m). Table 4-1 provides a guide for selecting proper
size cord for single-phase power sources based on am-
pacity rating.
