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.
Modification
Do not modify this equipment, as this may cause the equipment to malfunction.
