SECTION III
INSTALLATION
BEFORE INSTALLATION
Inspect the Load Bank for obvious damage such as broken or dented panels, cracked ceramic
insulators, broken wires, distorted hatches, or other component damage that may have occurred
during shipment.
*************************************************************
W A R N I N G
It is vitally important to install the Load Bank properly. Installation
errors may result in a catastrophic failure. The air pressure switches
and overtemperature switches in the Load Bank will guard against
some of these problems. If protective circuitry prevents application
of the load, determine the source of the problem. DO NOT
DISABLE THE AIR PRESSURE OR OVERTEMPERATURE
SWITCHES. This causes a safety hazard and will void our warranty.
The following installation instructions are critical to the safe
operation of the Load Bank.
Refer to the SAFETY
CONSIDERATIONS section of this manual.
*************************************************************
AIRFLOW CONSIDERATIONS
Even with an ample supply of cooling air, the Load Bank may overheat if it is not properly installed.
There are two types of airflow problems that must be avoided:
1.
Recirculating Airflow - If the hot, exhausted air is permitted to recirculate through the Load
Bank, it will reach such a high temperature and low density that it will no longer cool the
resistance load elements.
