Precautions
When working on or using this type of equipment, the following precautions must 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 power shelf that controller resides 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. Do not disconnect permanent bonding
provisions unless all ac inputs are disconnected.
•
High leakage currents may be possible on this type of equipment. Make sure the equipment
is properly safety earth grounded before connecting power.
•
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.
• 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. When equipped with ringer modules, hazardous voltages will be present on the
ringer output connectors.
In addition to proper job training and safety procedures, the following are some basic precautions
that must always be used:
•
Use only properly insulated tools.
•
Remove all metallic objects (key chains, glasses, rings, watches, or other jewelry).
•
Wear safety glasses. Fuses can produce sparks. High energy levels on busses and
distribution components can produce severe arcing.
•
Test circuits before touching.
•
Lock out and tag circuit breakers/fuses when possible to prevent accidental turn on.
•
Be aware of potential hazards before servicing equipment.
• Identify exposed hazardous electrical potentials on connectors, wiring, etc. (note the
condition of these circuits, especially wiring).
•
Use care when removing or replacing covers; avoid contacting circuits.
•
Generally, two persons must be present when working with power.
