Safety Guidelines
Electrical shock and fire hazards are avoided by using normal
installation procedures for electrical power equipment in an industrial
environment. Installation must be undertaken by suitably qualified
personnel. Note that this amplifier must be installed in an industrial
cabinet such that access is restricted to suitable qualified personnel.
Mechanical hazards are associated with potentially uncontrolled
movement of the motor shaft. If this imposes a risk in the machine,
then appropriate precautions must be made to electrically disconnect
the motor from the drive when personnel have access to moving parts
of the machine. Note also that the motor must be securely mounted at
all times.
Stored energy hazards are both electrical and mechanical.
●
Electrical hazards can be avoided by disconnecting the drive from
its power source and measuring the DC bus voltage to verify it has
reached a safe level or by waiting for the time indicated in the
warning on the front of the drive prior to removing the protective
covers or touching any connections.
●
Mechanical hazards require a risk analysis on the effects of stored
mechanical energy when the machine is running at speed, as well
as the potential for the conversion of electrical energy stored in
the drive being converted to mechanical energy. Electrical energy
may be stored in drive for the time indicated in the warning on the
front of the drive.
The following points should be observed for the safety of personnel.
These safety notes do not represent a complete list of the steps
necessary to ensure safe operation of the equipment. Contact your
nearest Allen-Bradley representative for additional information.
●
Only qualified personnel familiar with the equipment are
permitted to install, operate and maintain the device.
●
System documentation must be available and observed at all
times.
●
All non-qualified personnel are kept at a safe distance from the
equipment.
●
The system must be installed in accordance with local regulations.
●
The equipment is intended for permanent connection to a main
power input. It is not intended for use with a portable power input.
●
Do not power up the unit without the covers in place and the
protective conductor connected.
●
Do not operate the unit without connecting the motor conductor to
the appropriate terminal on the drive.
●
Always remove power before making or removing any
connection on the unit.
