5.0 INSTALLATION
5.1 Introduction
With a portable load bank, placement is not a permanent thing; however, because of its
mobile nature, extra attention is required whenever the load bank is moved. Whenever
the load bank is moved, even within the same room, the following warnings must be
observed.
In this section, you will find:

How to choose the load bank’s location.
5.2 Load Bank Location
The load elements in the load bank are cooled by a horizontal forced air system, which
discharges through the front of the cabinet. The
location of the load bank is of prime importance
and is one of the most critical factors involved in
safe operation. The load bank must be positioned
and installed to allow for a 4-foot intake clearance
as well as a 20-foot exhaust clearance. Never
point the exhaust at nearby surfaces or objects,
which may be adversely affected by high
temperatures. Never operate the load bank in a
confined 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 re-circulate through the cooling system. Never operate
the load bank in proximity to a sprinkler system.
See Figure 1 load bank placement image for more specific details when choosing a place
for your load bank.
WARNING
Reverse air-flow will damage load bank. Please observe the above image for how air
travels into and out of the load bank.
Note: Load bank warranty is void if incorrectly cooled.
High Voltage : Because this unit uses dangerous voltage, turn off the equipment and
disconnect power source before opening the load bank.
High Temperature : Due to the amount of heat generated during operation, allow the
equipment to cool before servicing or opening the load bank.
Rotating Equipment : Before opening the load bank, ensure that the power is removed,
and the fan has stopped completely.
For Operator Safety : Make sure this equipment is properly grounded when in use.
All compression type connections on fuse blocks, load blocks, and contactors should
be checked for tightness frequently. This check should be established as part of routine
maintenance.
