Operation ASCO 4900 Outdoor Resistive Load Bank • Part Number 1251794
4-1
SECTION IV
OPERATION
Refer to the Intelligent Handheld Terminal (IHT) Quickstart Guide for operation of the Load Bank.
*************************************************************
C A U T I O N
DO NOT operate the Load Bank over the rated voltage as this will
cause catastrophic failure in the Load Bank.
Do not apply DC voltages as the contactors do not have arc blowout
magnets. Also, the reactive load sections will react as low impedance
short circuit paths, resulting in a definite fire hazard.

C A U T I O N
The operation of the blower is vital to the safe operation of this Load
Bank. When the BLOWER is turned ON, the AIR FAILURE light
will come on momentarily until the blower accelerates up to its
operating speed, at which time the light will go off.
If the air switch prevents the load from being applied (AIR FAILURE
indicator light on), do not bypass the air switch. This will cause the
Load Bank to burn up. Do not attempt to operate the unit until the
problem is corrected. Refer to the SAFETY CONSIDERATIONS
section of this manual.
