Wiring the Relays
Note: All SmartPanel relays are low
voltage only rated at 500mA max
current. Under no circumstances is
high voltage to be connected to
the panel or come into any conduit
or backbox that the Panel uses.
The exact wiring of the relays depends
on your needs and the switching
configuration. Relay configuration using
the Configuration Utility is discussed in
Relays.
Note: Commons may have to be
combined when many relays
communicate with the same
device. Remember that commons
are not true ground (as relay
closures are electrically isolated
from ground and from one
another).
Note: Never combine the commons of two separate controlled devices. This may cause an
electrical short within one or both devices!
