Only qualified persons are allowed to wire the product. 
Be sure to shut off the user’s power supply. Wiring with the product 
energized is strictly prohibitted. 
The wiring must be conducted using cables complying with “Table 
3-3” firmly and secured to the product to prevent the external force 
of cables being applied to the terminals. Incomplete wiring or 
improper securing of wiring may cause electrical shock, excessive 
heat and fire. 
Ensure a stable power supply with no voltage surges. 
Ensure that an Earth Leakage Breaker is used in the power supply of 
the product. See “Table 3-3”.   
Use a power supply suitable for the specifications of the product. 
Be sure to connect the ground connection.   
Ensure that a lock out facility is availble on the power supply. 
Each product must have its own separate Earth Leakage Breaker. 
Otherwise there can be a risk of electric shock or fire. 
Do not modify the intenal electrical wiring of the product. Incorrect 
wiring may cause electrical shock or fire. Also, modifing the 
internal wiring will void the product’s warranty. 
Do not connect the ground to water line, gas pipe or lightening
