•When using the interconnect feature, all interconnected units must be powered with the same, independent supply.

•Polarity must be maintained throughout the interconnect wiring. Connect termi- nal 12 on unit 1 to terminal 12 on unit 2 and so on. Similarly, connect terminal 1 on unit 1 to terminal 1 on unit 2 and so on.

•Up to 10 units may be interconnected.
