This diagram is designed to take a PNP (Sourced) +24 VDC
signal from an ESFR fire suppression system. The ESFR
system will supply the +24 VDC power.
Run the +24 VDC signal wire to terminal 4 and route 0V COM to
terminal 7. There should be room in the terminal block to
accept both wires on terminal 7.
To enable the ESFR signal input see the programming steps
below. The drive will go into a fault condition once the 24VDC
signal is lost and will not allow fan operation until that signal
is restored.
