Grounding
Ground the supply system as instructed here and in the
individual component manuals.
Pump: use a ground wire and clamp. Loosen the
grounding lug locknut and washer. Insert one end of the
supplied ground wire into the slot in the lug and tighten
the locknut securely. Connect the other end of the wire
to a true earth ground. See F
IG
. 7.
Air and fluid hoses: use only electrically conductive
hoses.
Air compressor: follow the manufacturer’s recommen-
dations.
Dispense valve: ground through the connection to a
properly grounded fluid hose and pump.
Fluid supply container: follow the local code.
Solvent pails used when flushing: follow the local
code. Use only conductive metal pails, placed on a
grounded surface. Do not place the pail on a non-con-
ductive surface, such as paper or cardboard, which
interrupts grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure:
hold the metal part of the dispense
valve firmly to the side of a grounded metal pail, then
trigger the valve.
Connect Power Source
The electrical enclosure comes already attached and
wired to the ram; however, before the supply system
becomes functional you must connect the electrical
enclosure to a power source.
NOTE: Required voltage and amperage is noted on the
electrical enclosure label. Also see Table 1. Before run-
ning power to the unit, make sure the plant electrical
service meets the supply system’s electrical require-
ments.
NOTE: See Power Requirements , page 5, for circuit
protection requirements.
1. Open the electrical enclosure door (ED).
2. Have a qualified electrician perform the following
steps:
a. Connect your plant power to the electrical
enclosure power line filter according to local
codes. A 1-3/8 in. (35 mm) diameter opening is
provided on the side of the enclosure adjacent
to the label. This opening is suitable for a 1 in.
npt conduit or strain relief fitting (supplied).
b. Connect a power protective ground (DB) to the
center post on the line end of the power line fil-
ter.
The power source conduit is not an adequate ground
for the system. The unit must be bonded to either the
building ground or a true earth ground. To reduce the
risk of static sparking and electric shock, ground the
pump, the object being dispensed to, and all other
dispensing equipment used or located in the dispens-
ing area. All electrical wiring must be done by a quali-
fied electrician and comply with local codes and
regulations.

Have a qualified electrician connect power according
to national, state, and local safety and fire codes. Fail-
ure to do so may result in static spark or electric
shock.
