Power Supply Coolant Return Hose

coolant return fitting on the rear of the power supply. Note that the
coolant return fitting has left hand threads.
2. Connect the other end of the power supply coolant return hose to the
coolant out fitting on the RHF console. Note that the coolant out fitting

Work Ground Lead
1. Route one end of the #1/0AWG work ground lead through the middle
strain relief on the rear of the power supply and connect it to the work
terminal.
2. Connect the other end of the work ground lead to the star ground point
on the cutting table. The star ground point is generally referred to as
the common ground point on the cutting table where all subsystems of
the machine are grounded. This point is then connected to a driven
earth ground rod that should be as close as possible to the star
ground. The ground rod should have no other wires connected to it.
The ground rod should be at least 3/4 inches in diameter and should
be driven into the earth’s permanent moisture layer. The length of the
ground rod varies from installation to installation and should be
installed according to local and national codes. Refer to the National
Electrical Code, Article 250, Section H, Ground Electrode System for
additional information.
RHF Console Ground Connection
Perform the following steps to connect the chassis of the RHF console to
the cutting table. See figure below.
1. Connect one end of the RHF console ground lead to the ground stud
on the RHF console.
2. Connect the other end of the RHF console ground lead to chassis
ground on the cutting table. Make sure that good metal-to-metal contact is
made.
