Important Interconnect Notes
• When using the interconnect feature, all

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.
