SAFETY CONSIDERATIONS
Throughout this manual, you will find WARNING and CAUTION statements. Personal injury or
death may occur to an operator using or repairing the equipment if a WARNING statement is
ignored. Damage to the equipment and potentially hazardous conditions for personnel may occur if
a CAUTION statement is ignored.
Each Avtron unit is safety checked for opens and shorts, and the insulation is high potential tested to
ensure safe operation. All fuses, safety interlocks, and related safety equipment have been proven
reliable as part of the testing procedure of each unit.
As part of your safety program, an initial inspection after receiving the unit(s) and periodic
preventive maintenance and safety inspections should be conducted to ensure the reliability and
safety built into your Avtron equipment.
The Model K975A Load Bank is an industrial test unit designed to be used outdoors safely.
However, because the purpose of the Load Bank is to dissipate electrical energy, there are inherent
dangers to operators and equipment. These dangers are outlined in this section.
Electrical energy is transformed into heat by the resistors. This heat must be removed from the Load
Bank by the cooling blowers. If there is any restriction or stoppage of airflow, the Load Bank may
overheat and may even start a fire. It is recommended that:
1. The operator should read the manual before using the Load Bank.
2. Run an approved ground wire from the Load Bank ground lug to the generator frame. Run
an approved ground wire from the generator frame to a good earth ground.
3. Do not bypass the AIRFLOW safety switches or the OVERTEMPERATURE safety
switches to prevent nuisance tripping. The switches drop out if insufficient air is reaching
the load elements.
