Precautions when laying power supply wiring
[PRECAUTIONS]
[1] A circuit breaker capable of shutting down power supply to the entire system must be installed.
[2] A single switch can be used to supply power to units on the same system.
However branch switches, branch overload circuit interrupter must be selected carefully.
[3] Fit the power supply wiring of each unit with a switch and fuse as shown in the drawing.

[4] Use round crimp-style terminals for connecting wires to the power supply terminal block.
If unavailable, observe the following points when wiring.
•
Do not connect wires of different gauge to the same power supply terminal.
(Looseness in the connection may cause overheating.)
•
Use the specified electric wire. Connect the wire securely to the terminal. Lock the wire down without
applying excessive force to the terminal. (Tightening torque: 131N·cm ±10%)
