Connect Power - Graco Therm-O-Flow 200 Instructions - Parts Manual

Connect Power

The electrical control panel comes already attached and
wired to the ram, however before the supply unit
becomes functional you must connect the electrical con-
trol panel to a power source.
All electrical wiring must be done by a qualified elec-
trician and comply with all local codes and regula-
tions.
NOTE: Required voltage and amperage is noted on the
control panel label. Before running power to the unit,
make sure the plant electrical service meets the
machine's electrical requirements. Branch circuit protec-
tion shall be provided by the end user.
Use copper conductors rated 600 volts minimum and
167°F (75°C) minimum only. Torque to 55 in-lb (6.2
N•m).

1. Locate the opening in the control panel's top hous-
ing for the conduit that will enclose the wire from the
facility's power source. The hole will accept a cord
diameter range of 0.7–1.2 in (17–30 mm).
2. Thread the wire from the power source into the con-
trol panel housing, and then connect the power
source wires to the appropriate terminals on the
DISCONNECT switch.

To reduce the risk of fire, explosion, or electric shock,
the resistance between the supply unit components
and true earth ground must be less than 0.25 ohms.
3. Connect the ground wire to the ground lug. Have a
qualified electrician check the resistance between
each Therm-O-Flow system ground and the true
earth ground. The resistance must be less than 0.1
ohms. If the resistance is greater than 0.1 ohms, a
different ground site may be required. Do not oper-
ate the system until the problem is corrected.
NOTE: Use a meter that is capable of measuring resis-
tance at this level.
