Precautions
When working on or using this type of equipment, the
following precautions should be noted:
•
This unit must be installed, serviced, and operated only by
skilled and qualified personnel who have the necessary
knowledge and practical experience with electrical
equipment and who understand the hazards that can arise
when working on this type of equipment.
•
The equipment could be powered by multiple ac inputs.
Ensure that the appropriate circuit protection device for
each ac input being serviced is disconnected before
servicing the equipment.
•
For equipment connected to batteries, disconnecting the ac
alone will not necessarily remove power to the equipment.
Make sure the equipment is not also powered by the
batteries or the batteries are not connected to the output of
the equipment.
•
High leakage currents may be possible on this type of
equipment. Make sure the equipment is properly safety
earth grounded before connecting power.
•
Hazardous energy and voltages are present in the unit and
on the interface cables that can shock or cause serious
injury. Follow all safety warnings and practices when
servicing this equipment. Exercise care when servicing this
area.
•
Batteries may be connected in parallel with the output of the
rectifiers. Turning off the rectifiers will not necessarily
remove power from the bus. Make sure the battery power is
also disconnected and/or follow safety procedures while
working on any equipment that contains hazardous
energy/voltage.
•
In addition to proper job training and safety procedures, the
following are some basic precautions that should always be
used:
–
Use only properly insulated tools.
–
Remove all metallic objects (key chains, glasses, rings,
watches, or other jewelry).
