PRIMARY INSPECTION
Preventative visual inspections of the
shipping crate and Load Bank is ad-
vised. Physical or electrical problems
due to handling and vibration may oc-
cur. Never apply power to a Load Bank
before performing this procedure. The
following Nine Point/30 Minute Inspec-
tion is recommended before installa-
tion, as part of the 50 hour / 6 month
maintenance schedule and whenever
a Load Bank is relocated:
1. If crate shows any signs of damage
examine the Load Bank in the cor-
responding areas for signs of initial
problems.
2. Check the entire outside of the
cabinet for any visual damage which
could cause internal electrical or
mechanical problems due to reduced
clearance.
3. Operate all hinged panels and doors
for smooth and safe operation, try all
latches and knobs.
4. Rotate and push all switches through
all positions to ensure smooth opera-
tion.
5. Check cooling system by inspecting
fan motor and blade. Slowly rotate
blade by hand and note clearance
of blade tip through its rotation near
the housing. Observe free rotation
of motor shaft.
6. Inspect all relays, timers, and control
modules by opening all accessible
panels. Make sure all components
are secure in their bases and safety
bails are in place. Spot check electri-
cal connections for tightness. If any
loose connections are found inspect
and tighten all remaining connec-
tions.
7. Examine all accessible internal
electrical components such as fuses,
contactors and transformers. Check
lugged wires at these components.
8. Inspect bottom of crate/enclosure
for any components that may have
jarred loose during shipment such as
indicator light lenses, switch knobs,
etc.
9. Visually inspect element chamber
for foreign objects, broken ceramic
insulators, mechanical damage.
LOAD BANK LOCATION
The load elements in this Load Bank
are cooled by a horizontal forced air
system which discharges through the
rear of the cabinet. Location of the Load
Bank is of prime importance and should
be done by trained personnel. It is one
of the most critical factors involved in
safe operation. The Load Bank must
be positioned and installed according
to large airfl ow requirements. Never
point the exhaust at a nearby surface or
object which may be adversely affected
by high temperature. Never operate the
Load Bank in a confi ned space without
regard for adequate intake of air and
provision for exit of high temperature
exhaust. Consider that the Load Bank
and a nearby generator set may have to
compete for cooling air. Never bounce
hot exhaust air off nearby objects and
allow it to recirculate through the cooling
system. Never operate the Load Bank
in proximity to a sprinkler system.
If any problems are observed
during Primary Inspection call
