WARNING
and
CAUTION
statements. Personal injury or
death may occur to an operator using or repairing the equipment if a

Each Avtron unit is safety checked for opens and shorts, and the insulation is high potential tested to
ensure safe operation. All 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 Avtron Model K922A Load Bank is an industrial test unit designed to be used outdoors safely.
However, because the function of the Load Bank is to dissipate electrical energy, there are inherent
dangers to operators and equipment. These dangers are outlined in this section.
In the K922A, electrical energy is transformed into heat by the resistors. This heat must be removed
from the Load Bank by the cooling fans. 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 and understand the manual before operating the Load Bank.
2.
Run approved ground wires from the Load Bank ground bus bars located in the medium
voltage enclosure, low voltage enclosure, and ground pad on the Load Bank frame to the
system grounding network. Size ground wire in accordance with the National Electric Code
and any local codes.
3.
Do not bypass the airflow safety switches or overtemperature switches to prevent nuisance
tripping. The switches are designed to drop out the load if insufficient/overtemperature
exhaust air is reaching the load elements.
