OC129A-2.qxp 01.10.1 7:34 PM Page 56 4-3 Connection method (1) Connections in the power supply cord. 1. Connect the power supply cord to the power supply terminal-block and fix it in-place with a tie-wrap. Connect a single phase 200V AV (220, 230, 240V) to A N . As E is the GND terminal, be sure to ground the earth wire. 2. Connect the transmission line to the transmission terminal-block and fix it in-place with a tie-wrap. Use a Ω1.6 (AWG 14) or above two-wire cable for the transmission line.

OC129A-2.qxp 01.10.1 7:34 PM Page 58 2. Set the address number (from SW1-1 to SW1-6) in the dip switch when a centralized remote controller is being used. The address is the control number of each unit in the centralized control system. As the address serves as a time-delay device as well, sequential starts (all units are triggered collectively by one single ON instruction) must be set with different address numbers (greater than O) for each adapter.
