DANGER
• Current transformer circuit
Never allow the current transformer (CT) secondary circuit connected to this equipment to be
opened while the primary system is live. Opening the CT circuit will produce a dangerously high
voltage.
WARNING
• Exposed terminals
Do not touch the terminals of this equipment while the power is on, as the high voltage generated
is dangerous.
• Residual voltage
Hazardous voltage can be present in the DC circuit just after switching off the DC power supply. It
takes about 30 seconds for the voltage to discharge.
• Fiber optic
Do not view directly with optical instruments.
CAUTION
• Earth
The earthing terminal of the equipment must be securely earthed.
CAUTION
• Operating environment
The equipment must only be used within the range of ambient temperature, humidity and dust, etc.
detailed in the specification and in an environment free of abnormal vibration.
• Ratings
Before applying AC voltage and current or the DC power supply to the equipment, check that they
conform to the equipment ratings.
• Printed circuit board
Do not attach and remove printed circuit boards when DC power to the equipment is on, as this
may cause the equipment to malfunction.
• External circuit
When connecting the output contacts of the equipment to an external circuit, carefully check the
supply voltage used in order to prevent the connected circuit from overheating.
• Connection cable
Carefully handle the connection cable without applying excessive force.
