INSTALLATION AND WIRING 2.3 Wiring (1) Strip off the sheath of the cable to wire. Strip off the sheath about the size below. If the length of the sheath pealed is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off. Wire the stripped cable after twisting it to prevent it from becoming loose. - Page 12 INSTALLATION AND WIRING (3) For wiring of the FR-A series 22K or less and the FR-F series 30K (FR-F720-01250, FR-F740- 00620) or less, route wires between the control circuit terminal block and front cover. If cables can not be routed between the control circuit terminal block and front cover due to the increased number of cables, remove a hook of the front cover and use a space become available.
