Important Interconnect Notes

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

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