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 K711 Load Bank is an industrial test unit designed to be used indoors safely. The unit
will be installed in an enclosure. However, because the function of the Load Bank is the dissipation
of 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 customer-supplied cooling fans/blowers. If there is any restriction or stoppage of
airflow, the Load Bank will overheat and may 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(s) to the generator frame.
Run an approved ground wire from the generator frame to a good earth ground. Size ground
wire in accordance with National Electrical Code and any local codes.
3.
Do not bypass the exhaust over-temperature switch to prevent nuisance tripping.
4.
Replace any burned out bulbs on the control panel. Each lamp is an indication that a system
is active or has failed and is important to the operation of the Load Bank and safety of the
operator.
5.
Maintenance personnel must always exercise caution when the access panels or intake
screens are removed. Personal injury from electrical shock may result if all sources of power
