  Preparation 
 
1. Strip the sheath from both ends of the cable. 
 
2. Disassemble the power supply connector. Attach crimp terminals (mounting screw dia.: 
M3.5) to one end of the cable to crimp them to L, N, E inside of the connector, then 
reassemble the power supply connector. 
 
3. Connect the other end of the cable to a terminal (e.g. crimped terminal) that is 
compatible to the secondary side of the earth leakage breaker.

Prepare the crimp terminal which is suitable for the cable 
diameter. 
The electrical facilities should be installed and wired in accordance 
with local laws and regulations of each country and by a person 
who has knowledge and experience. 
Check the power supply. Operation with voltages, capacities and 
frequencies other than the specified values can cause fire and 
electrical shock. 
Wire with an applicable cable size and terminal. Forcibly mounting
