Safety Tests
The information contained in this section of the commissioning
chapter must be completed in order to ensure that the commissioning
continues in an environment safe to all those involved in servicing
the drive line-up. Every point included in this section must be
completed prior to continuing with the drive commissioning. Ensure
that commissioning of this drive line-up is performed in accordance
with local safety standards.
A T T E N T I O N A T T E N T I O N Servicing energized industrial control
equipment can be hazardous. Severe injury or
death can result from electrical shock, burn, or
unintended actuation of control equipment.
Hazardous voltages may exist in the cabinet
even with the circuit breaker in the off position.
Recommended practice is to disconnect or lock
out control equipment from power sources, and
confirm discharge of stored energy in
capacitors. If it is necessary to work in the
vicinity of energized equipment, the safety
related work practices of NFTA 70E, Electrical
Safety requirements for Employee Work
places, must be followed.
A T T E N T I O N A T T E N T I O N Before attempting any work, verify the system
has been locked out and tested to have no
potential.
Lockout Tagout
Prior to opening the doors to the drive line-up cabinets, proper lockout
tagout procedures must be performed to ensure that the working
environment is safe. In addition, the equipment must be tested for
potential prior to servicing the equipment. Even though the input to the
drive may be open, it is still possible for potential to be present.
A T T E N T I O N A T T E N T I O N Live capacitors in circuit. Before touching
anything, ensure that the drive is isolated from
medium voltage and wait five minutes for the
capacitors to discharge. Test the circuit for
potential before servicing the equipment.
Failure to do so can result in severe injury or
death.
