RTS451KEY and interconnect feature:
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.
