Commissioning
326 PRS-7367
Do not touch the circuit during operation. There may be fatal voltage and current.
Strict compliance with safety regulations. Work in high voltage environment need to be
serious to avoid personal injury or equipment damage.
When measuring signals in an open circuit, remember to use a properly isolated test clamp
that can have fatal voltages and currents.
During normal operation, never disconnect or connect the wires or connectors connected
with the terminals. It may cause deadly dangerous voltage and current, may also interrupt
the operation of the equipment, damage the terminals and the measuring circuit.
Never disconnect the secondary winding of the current transformer. Current transformers
that operate when the secondary windings are open will create strong potentials that may
damage the transformers and may cause personal injury.
When the protective device is energized, never plug the module. Hot plug may damage the
protection device and measuring circuit, may also result in injury.
10.2.2.2 Caution Signs
Do not connect the protective shell to the live wire, charging the shell may damage the internal
circuit.
During installation and commissioning, be careful not to get an electric shock if you touch
the leads and connecting terminals
10.2.2.3 Notice Signs
Do not modify the settings in the running protection device. After modify the setting, verify
it according to the rules.
10.2.2.4 Anti-static Signs
Remember to avoid touching circuits, including electronic circuits, and the device may be
damaged if subjected to static electricity. Electronic circuits may also contain deadly high
voltages.
Remember to use a certified conductive bag when transporting the module. Remember
to connect the anti-static wristband to the ground when handling the module and
remember to operate it on a suitable anti-static surface. Static electricity discharge may
cause damage to the module.
Remember to wear the anti-static wristband connected to the ground when replace the
module, Static electricity discharge may damage the module and protection device.
10.2.2.5 Earthing Signs
Regardless of operating conditions, remember to connect the protective device to the
earth, also needed for special occasions such as testing, demonstrating and off-line
configuration on the desk. Operation of the protective device without proper earthing
may damage the protective device and the measuring circuit and may also cause an injuring
accident.
