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 dangerous 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.
CAUTION
 Earth
Earth the earthing terminal of the equipment securely.
CAUTION
 Operation conditions
Use the equipment within the range of ambient temperature, humidity and dust as detailed in the
specification and in an environment free of abnormal vibration.
 Ratings
Before applying AC voltage and current or DC power supply to the equipment, check that they
conform to the equipment ratings.
 Printed circuit board
Do not attach and remove the printed circuit board while the DC power to the equipment is on, as
this may cause the equipment to malfunction.
 Battery
Avoid placing the back side of the printed circuit board with a battery (SPM board) directly on
top of a metal conductor or wrapping it with metal foil, as this may short-circuit the battery power
supply. However, the board may be placed on an antistatic conductive mat.
 External circuit
When connecting the output contacts of the equipment to an external circuit, carefully check the
supply voltage used and 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, and any such
modifications will invalidate the warranty.
