Caution
1. For the relay RYA, use a relay with a rated contact capacity of 160 mA or more.
2. Relays that can be connected between the EMG+ and EMG- terminals of the extension unit are subject to limitations in
that the total sum of “10 mA x number of controllers connected to the extension unit” and “coil current of the relay
connected between the EMG+ and EMG- terminals” must not exceed 160 mA.
3. For the drive power source of each connected controller, refer to the first step guide or operation manual of the
controller.
4. Do not short the EMG+ (orange) and EMG- (gray) wires of the controller connection cable.
