The electrical control panel comes already attached
and wired to the ram, however before the supply unit
becomes functional you must connect the electrical
control panel to a power source.
All electrical wiring must be done by a qualified
electrician and comply with all local codes and
regulations.
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 protection 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
housing for the conduit that will enclose the wire
from the facility’s power source. The hole will
accept a a cord diameter range of 0.7–1.2 in
(17–30 mm).
2. Thread the wire from the power source into the
control 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 operate the system until the
problem is corrected.
Note
Use a meter that is capable of measuring
resistance at this level.
