SECTION I
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 tested 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 LPH400 Load Banks are industrial test units designed for safe use indoors.
However, because the Load Bank’s function is to dissipate electrical energy, there are inherent
dangers to the operators and to the equipment. These dangers shall be 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 fan. If there is any restriction or stoppage of airflow, the Load Bank
may overheat and may even start a fire. The following events must be conducted if safe
operation of the Load Bank is to take place.
1.
Read the manual before operating Load Bank.
2.
An approved ground conductor wire from the Load Bank ground point and the generator
frame to a good earth ground must be connected.
3.
Do not bypass the airflow switch to prevent nuisance tripping. The switch is designed to
drop out the load if sufficient air is not reaching the load elements.
