Installation Guidelines 3-25
3.15.2 Grounding the RFI Filter
The optional RFI filter may produce high ground leakage currents. Surge suppression
devices are incorporated into the filter to clamp line surges to a limited voltage above
ground potential. The filter must be permanently installed and solidly grounded to the
supply neutral. Grounding must not rely on flexible cables and should not include any
form of plug or socket that would permit inadvertent disconnection. The integrity of this
connection should be checked periodically.
3.16 Commissioning the Drive
Working with energized industrial control equipment can be hazardous. Hazardous
voltages may exist in the cabinet even with the circuit breaker in the off position.
Multiple sources of power may be connected to this Power Module. Disconnect and
lock out control equipment from power sources, and discharge stored energy in
capacitors before coming into contact with any equipment in this cabinet.
During start-up it will be necessary to work in the vicinity of energized equipment. The
Safety Related Practices of NFPA 70E,
Electrical Safety for Employee Workplaces
must be followed at all times. DO NOT work alone on energized equipment. Failure to
observe these precautions could result in severe bodily injury or loss of life from
electrical shock, burn, or unintended actuation of controlled equipment.
Note that for maintenance and setup procedures, the Power Module may be operated
without a motor connected.
!
ATTENTION:RFI filters can only be used with AC supplies that are
nominally balanced with respect to ground. In some countries,
three-phase supplies are connected in a three-wire configuration with
one phase grounded (Grounded Delta). The filter must not be used in
Grounded Delta supplies.
!
ATTENTION:Only qualified personnel familiar with the construction and
operation of this equipment and the hazards involved should install,
adjust, operate, or service this equipment. Read and understand this
manual and other applicable manuals in their entirety before proceeding.
Failure to observe this precaution could result in severe bodily injury or
loss of life.
ATTENTION:Hazard of electric shock exists in this Power Module.
Power circuit components are floating with respect to ground. Use only
approved methods of isolating test equipment when making
measurements in power circuits.
ATTENTION:Hazardous voltages may exist in the cabinet even with the
circuit breaker in the off position. Multiple sources of power may be
connected to this Power Module. Disconnect and lock out control
equipment from power sources, and discharge stored energy in
capacitors before coming into contact with any equipment in this cabinet.
ATTENTION:The Power Module contains ESD (Electro-Static
Discharge) sensitive devices. Static control precautions are required
when installing, testing, servicing or repairing this assembly. These
precautions should be applied when working with logic boards and any
components in the power section. A properly grounded wrist strap should
be worn when contacting any component in the Power Module.
