CAUTION
This load bank is high-powered, technical, industrial equipment operating at dangerous
voltages, and temperatures. It is capable of damage to itself or property or personnel,
if improperly used. It is not a consumer product. It must be installed, connected, and
operated by personnel properly trained and experienced in its use. An operator’s
manual is supplied with each load bank. It is imperative that the operator be familiar
with its contents and has access to it during operation.
The following cautions should be observed before and during operation:
1. Check all aspects of the load bank (intake/exhaust screen, louvers, fans, and load
elements) for foreign objects.
2. Position and install load bank with great consideration given to large cubic airflow
requirements, exhaust temperature and velocity. The exhaust temperature of a
large load bank rapidly diminishes downstream but can easily exceed 300°F within
20 feet of exhaust outlet. Therefore, do not point exhaust at any nearby surface or
object, which may be adversely affected by high temperature. This includes but is
not limited to painted surfaces, tar paper and asphalt roofs, water sprinkler heads,
fire alarms, and volatile material.
Do not use in confined spaces with less than a 4-foot clearance for intake air and
less than a 20-foot clearance for exit of high temperature exhaust. Do not permit
vertical airflow unit with wheels to sink into soft surfaces thereby cutting off bottom
air intake. Be concerned with possibility that the load bank may have to compete
with cooling air requirements of a nearby running engine generator set where cool -
ing air intake to a confined space may not be adequate for both engine and load
bank. Be especially careful not to bounce hot exhaust air off nearby obstructions for
re-circulation through the load bank.
3. Verify that all control switch positions are correct for intended usage before making
connection.
4. The load cables carry high amperage. Be constantly aware of possibility of
inductively heating adjacent ferrous objects to temperatures sufficient to damage
cable insulation.
5. If load bank does not have a fan reversal switch, give extra attention to proper
phasing of power cable and external control power connection to assure proper fan
rotation.
6. Always connect safety ground cable to a proper ground. Do not rely on a possible
grounded neutral somewhere else in the system.
7. Do not let equipment operate unattended for long periods of time.
8. Do not store or operate in rain or spray unless unit is designed for this service or
adequate protection is provided.
9. Routinely inspect all components and electrical connections for tightness and
integrity.
10. Repair any damaged or degraded components and wiring without delay.
