Commissioning 4-15
7000 “B” Frame 7000-UM150I-EN-P – June 2013
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.
