1. Remove 2 screws to detach the electric component cover.
2. Route each cable through the wiring intake into the electric component box.
(Procure power supply cable and control cable locally.)
3. Securely connect the power supply cable and control cable to the terminal
blocks.
4. Secure the cables with clamps outside the electric component box.
5. Attach the electric component cover as it was.
• Do not allow slackening of the terminal screws.
• Always install earth.
(Earth cable dia: Thicker than 1.6 mm, 5/8 inch (AWG14))
• Fix power supply cable and control cable to electric component box by using
buffer bushing for tensile force. (PG connection or the like.)
• Tape is affi xed over the conduit hole used for connecting the electric wiring.
Please remove this tape if making a connection through the hole.
