3. The following illustration shows proper connection of a
customer-supplied ground cable to a grounding stud pro-
vided on the rear panel of the power supply.

D. Routing Of Torch Leads
1. To minimize RF interference, position torch leads as
far as possible from any CNC components, drive mo-
tors, control cables, or primary power lines. If cables
have to pass over torch leads, do so at an angle. Do not
run the plasma control or other control cables in paral-
lel with the torch leads in power tracts.
2. Keep torch leads clean. Dirt and metal particles bleed off
energy, which causes difficult starting and increased chance
of RF interference.
3.09 Filling Power Supply Coolant
The ambient temperature of the environment where the Power
Supply will be located determines the coolant to be used. The
Extra-Cool
TM Coolant supplied with the system can be used in
ambient temperatures down to 10° F (-12° C).
Optional Ultra-Cool TM Coolant should be used in areas where
the ambient temperature drops down to -27° F (-33° C).
CAUTION
Use only Thermal Arc Torch Coolant. Use of any
other coolant can result in torch damage, insuffi-
cient thermal protection, and/or pilot arc interfer-
ence.
1. Locate the coolant deionizer bag and remove from
the plastic shipping bag.
2. Remove the coolant filler cap from the reservoir at
the rear of the Power Supply.
3. Carefully pour enough of the supplied Thermal
Arc Torch Coolant into the reservoir to fill it.
4. Reinstall the reservoir coolant filler cap.
5. After the complete system has been installed do
the following procedure to make sure the coolant
has been pumped through the system (see NOTE):
NOTE
Depending on the length of the torch leads ordered
with the system more coolant may need to be added
after turning ON the system for the first time.
a. Place the ON/OFF Switch to ON.
b. After about 10 seconds the system will shut down
(see NOTE).
NOTE
DO NOT allow the pump to operate for more than
10 seconds the first time the system is turned ON.
c. Place the ON/OFF switch to OFF.
d. After 10 seconds place the ON/OFF switch to ON again.
e. Repeat steps ‘b’ through ‘d’ until the system no
longer shuts down. Depending on the length of
the torch leads this sequence may need to be
done three to five times.
f. After the system stays operational allow the pump
to operate for ten minutes to properly purge any air
from the coolant lines before using the system.
6. Remove the filler cap, re-fill the reservoir, place the deion-
izer bag into the basket in the coolant reservoir and re-
install the filler cap.
