If there is unlocked access to the equipment, care should be taken by all personnel to
avoid electric shock or energy hazards.
Voltage and current connections should be made using insulated crimp terminations to
ensure that terminal block insulation requirements are maintained for safety. To
ensure that wires are correctly terminated, the correct crimp terminal and tool for the
wire size should be used.
Before energizing the equipment, it must be grounded (earthed) using the protective
ground (earth) terminal, or the appropriate termination of the supply plug in the case of
plug connected equipment. Omitting or disconnecting the equipment ground (earth)
may cause a safety hazard.
The recommended minimum ground (earth) wire size is 2.5 mm
2
(#12 AWG), unless
otherwise stated in the technical data section of the product documentation.
Before energizing the equipment, the following should be checked:
Voltage rating and polarity
CT circuit rating and integrity of connections
Protective fuse rating
Integrity of ground (earth) connection (
where applicable
)
Equipment operating conditions
The equipment should be operated within the specified electrical and environmental
limits.
Current transformer circuits
Do not open the secondary circuit of a live CT since the high voltage produced may be
lethal to personnel and could damage insulation.
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.
Do not attempt to perform installation, maintenance, service or removal of this device
without taking the necessary safety precautions to avoid shock hazards. De-energize
all live circuit connections before work begins.
