Safety Considerations
Avtron Model LPH400 • Resistive Load Bank
Part Number LPH400D30693-1
1-2
4.
Do not bypass any fuses which have blown. Bypassing fuses can result in damage to the
equipment and potentially hazardous conditions for the operator. If a fuse is blown,
determine the cause of the blown fuse and correct the situation.
5.
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.
6.
Maintenance personnel must always exercise caution when access panels are removed.
Personal injury from electrical shock or from the moving fan blade may result if all
sources of power are not disconnected before servicing. Maintenance work must be
conducted only by qualified personnel.
7.
The Load Bank should be operated in a cool, well ventilated area as described in the
INSTALLATION section of this manual. Do not allow exhaust air to recirculate through
the Load Bank.
8.
Venting the heated air from the Load Bank exhaust is a potential hazard. The Load Bank
should be used in a cool, well ventilated area.
9.
Allow cool air to pass into the unit to cool the elements. Do not allow the unit to be
placed where hot exhaust air can recirculate back through the unit causing a constant rise
in cooling air temperature.
10.
After running a load test, residual heat should be removed from the Load Bank by
allowing the fan to operate for a few minutes after load is removed. This procedure is not
required for maintaining Load Bank integrity, but it may guard operating personnel from
possible burn injuries.
11.
The operator should avoid coming in contact with the resistor elements or surrounding
covers during and for some time after operation. These portions of the Load Bank
become quite hot and may result in a serious burn, should contact be made with them.
12.
Do not allow objects to enter or block the air intake or exhaust of the Load Bank. A
blockage could cause Load Bank overheating. If an object enters the screens, it will
cause damage to the resistor elements, possibly shorting them and causing shock and fire
hazards.
13.
Operators must not operate the Load Bank with the access panels, cover, or screens
removed. To do so exposes the operator and other persons to possible personal injury
from electrical shock or from the moving fan blade.
14.
Keep the hinged cover on the customer connection access box (Load Connection
Compartment) closed at all times during testing and while power is on the load bus.
