Safety Points
Safety Precautions
The following instructions are general safety precautions that are not necessarily related to any
specific part or procedure, and do not necessarily appear elsewhere in this publication. These
precautions must be thoroughly understood and applied to all phases of operation and maintenance.
This manual contains various
Warning
and
Caution
statements. Personal injury or death may occur
to an operator and/or technician if a warning statement is ignored. Equipment damage or hazardous
conditions for personnel could result if caution or warning statements are ignored. Carefully read and
review this instruction manual, supplemental manuals, and all electrical schematic/interconnection
drawings provided with the Load Bank prior to installation and operation.
Keep Away From Live Circuits
Operating and Maintenance personnel must at all times observe normal safety regulations. Do not
replace components or make adjustments to equipment with power turned on. To avoid casualties,
always remove power to the entire system. Turn off and disconnect the main-power source under test.
Disconnect all sources of power to the Load Bank (Main input load bus, blower motor circuit, and 120
VAC control circuits).
Shock Hazard
Load Banks contain lethal voltages when connected to the power source. Power to the load resistors
(main input load bus), power to fan motor circuits, and power to 120 VAC control circuits must be
removed before servicing. Allow adequate time after removing power before servicing or touching any
components.
Do Not Service or Adjust Alone
Under no circumstances should any person reach into an enclosure for the purpose of service or
adjustment of equipment except in the presence of someone who is capable of rendering aid.
Safety Earth Ground
An uninterruptible and approved earth ground must be supplied from the main power source. Serious
injury or death can occur if this grounding is not properly supplied. Grounding of this equipment should
be done by qualified personnel only and must be installed in accordance with all applicable national
and local electrical codes and regulations.
Chemical Hazard
No chemicals are included in the manufacturing or operation of this unit. There are no chemical
hazards to consider.
Emergency Aid
Personnel working with or near high voltages should be familiar with modern methods of resuscitation.
Potentially Hazardous Operator Conditions
Read this manual prior to operation.
Always run an approved ground conductor from the load bank frame to the power source under
test which in turn must be properly earth grounded.
