Industrial Power Corruptor Manual Rev 1.00
2.2.6.2 Three-Phase wye (star) power connections
Warning: Death, serious injury, or fire hazard could result from improper
connection of this instrument. The rear of the IPC is a high voltage, high
current area. Follow industry standard safety precautions at all times. Do not
make electric power connections unless you are qualified to do so. Do not
operate this instrument until you have received appropriate training and are
familiar with this entire manual.
Follow all local safety codes, practices, and requirements.
They take precedence over the instructions here.
Disconnect and lock out power before making or removing
connections to your IPC.
Conductors to the source side terminal blocks of your IPC
should be connected to a power source that is equipped with a
disconnect switch, and with an appropriately sized current-
limiting device (fuse or circuit breaker).
Avoid lengthy
conductors between this power source and your IPC; install your
IPC as close as practical to this power source.
Always install protective earth conductors to both source-
and load-side protective earth terminal blocks) with a cross
section adequate to carry all available current.
All conductors connected to the IPC must be stranded, with
insulation temperature rating of at least 105°C, a voltage rating
equal to or greater than the voltage supplied, and of adequate
cross-section for the available current.
Make sure that it is impossible for any person to touch any
bare wires or terminal block contacts once the terminations have
been made.
If you are using wire conductors smaller than #2A
WG (34
mm
2
), insert the conductor in a wire adaptor provided with your
IPC, then insert the wire adaptor in the IPC terminal block.
Failure to use a wire adaptor will result in poor clamping to the
conductor and dangerous access to high voltage wires/surfaces.
As a standard practice, mount wire adaptors in any terminal
blocks that do not have conductors inserted. This will prevent
finger access to potentially high voltage terminal block contacts.
