i.
Use the conduit hole located at the bottom right
of the manifold cabinet to route conduit to supply 120
VAC to the power supply. 110 VAC to 240 VAC, 50 to 60
Hz single phase may be used with all units.
Connect the final line hi/lo pressure switch wires to
the correct location. There is a 12” length pair of low
voltage wires with a near the PLC with a lever nut on
the end. Make sure the wire is routed in a way that the
manifold cabinet door can open without stretching the
wire.
Connect the Emergency Reserve transducer and
pressure switch to the correct terminal block near the
PLC. The transducer and pressure switch are both
installed on the emergency reserve regulator.
The emergency reserve pressure switch and pressure
transducer wiring should be routed through the hole
from which the emergency reserve is connected. The
wiring should be routed down the side of the manifold,
across the bottom and up to the controls to maintain
accessibility to all of the plumbing components. Once
the wires reach the bottom of the manifold the user
should be able to follow the routing of the other
transducer and pressure switch.
NEMA 4 (optional)
If the optional NEMA 4 enclosure is installed, route the
power and low voltage wires through the appropriate
weatherproof grommet.
