System Preparation 3-3
WARNING:
1.
Be sure to connect the equipotential wire before inserting the power
plug into the receptacle; be sure to pull out the power plug from the
receptacle before disconnecting the equipotential wire; otherwise
electric shock may result.
2.
When you connect another device to this system, you should use
the equipotential wire to connect each of equipotential terminals;
otherwise electric shock may result.
3.
Connect the earth cable before turning ON the system. Disconnect
the earth cable after turning OFF the system. Otherwise, electric
shock may result.
4.
DO NOT connect this system to outlets with the same circuit
breakers and fuses that control the current to devices such as life-
support systems. If this system malfunctions and generates
overcurrent, or when there is an instantaneous current at power ON,
the circuit breakers and fuses of the building’s supply circuit may be
tripped.
