CONTROL POWER SUPPLY
CAUTION:
No Controls (relays, etc.) should be
mounted in the Smart Panel
enclosure or connected to power
supplies in the control panel.
Additionally, control wiring not
connected to the Smart Panel should
not be run through the cabinet. This
could result in nuisance faults.
CAUTION:
Any inductive devices (relays) wired
in series with the flow switch for start/
stop, into the Alarm circuitry, or pilot
relays for pump starters wired
through motor contactor auxiliary
contacts must be suppressed with
YORK P/N 031-00808-000
suppressor across the relay/
contactor coil.
Any contacts connected to flow
switch inputs or BAS inputs on
terminals 13 - 19 or TB3, or any other
terminals, must be suppressed with
a YORK P/N 031-00808-000
suppressor across the relay/
contactor coil.
CAUTION:
Control wiring connected to the
control panel should never be run in
the same conduit with power wiring.
