EQUIPMENT OPERATING CONDITIONS
The equipment should be operated within the specified electrical and environmental limits.
3.1
Current transformer circuits
Do not open the secondary circuit of a live CT since the high level voltage produced may be
lethal to personnel and could damage insulation.
be installed with the correct polarity, to avoid possible damage to the equipment.
3.2
Insulation and dielectric strength testing
Insulation testing may leave capacitors charged up to a hazardous voltage. At the end of
each part of the test, the voltage should be gradually reduced to zero, to discharge
capacitors, before the test leads are disconnected.
3.3
Opening Enclosure
There are no customer replaceable PCB cards or components within the enclosure, so the
enclosure should not be opened.
4.
DECOMMISSIONING AND DISPOSAL
Decommissioning:
The auxiliary supply circuit in the relay may include capacitors across
the supply or to earth. To avoid electric shock or energy hazards,
after completely isolating the supplies to the relay (both poles of any
dc supply), the capacitors should be safely discharged via the external
terminals prior to decommissioning.
Disposal:
It is recommended that incineration and disposal to water courses is
avoided. The product should be disposed of in a safe manner. Any
products containing batteries should have them removed before
disposal, taking precautions to avoid short circuits. Particular
regulations within the country of operation, may apply to the disposal
of lithium batteries.
