HD Cable Installation and Care
for Iso-FlorHD and VC Systems
Description
SeeFigure1.
This instruction sheet provides general guidelines for the installation and care of
electrostatic cables intended for use with HD and VC Iso-Florunits. For more
specific instructions, refer to your Iso-Flo system or power supply manual.
The electrostatic cable conducts high voltage between the electrostatic power
supply and the Iso-Flo unit. The electrostatic cable is constructed of a conductive
fiber core (1) surrounded by a corona guard (2) and a high-dielectric sheath (3).
Over the corona guard and sheath is a braided conductor (4). The braided
conductor grounds the gun through the power supply.
The braided conductor (4) is covered by a thin insulating sheet (5). The insulating
sheet is covered by a durable outer covering (6). This covering serves as an
insulator and also protects the cable from wear and contaminants.

A connecting nut is located at each end of the electrostatic cable. The connecting
nuts are internally connected to the conductive braid within the cable to provide the
grounding necessary for safe operation. One connecting nut is connected to the
power supply, and the other is connected to the Iso-Flo unit. A brass identification
tag is attached to the power supply end.

Cable Installation
WARNING: Allow only qualified personnel to perform the following tasks. Follow
the safety instructions in this document and all other related documentation.
Cable Connections to Iso-Flo HD and VC Units
WARNING: Allow only qualified personnel to perform the following tasks. Follow
the safety instructions in this document and all other related documentation.
1. See Figure 4. Install the cable into side of Iso-Flo cabinet:
a. Clean the Iso-Flo end of the cable with a clean, dry, lint free cloth.
b. Route the cable whip (3) through the adapter (1) on side of the
Iso-Flo cabinet.
c. Thread the cable fitting (4) onto the adapter (1) until hand- tight.
NOTE: On an Iso-Flo dolly system, the adapter (1) is located on a bracket inside
of the Iso-Flo Manual cabinet. Refer to the applicable Iso-Flo Dolly System
instruction sheet for cable installation.

NOTE: Use the tube reducer fitting shipped with the cable.
2. See Figure 5. Install the tube reducer fitting onto the cable whip:
a. Loosen the brass nut (2) and push the cable whip (1) through the brass nut
until the cable washer (5) bottoms out against the tube reducer fitting (6).
NOTE: The back ferrule (3) and front ferrule (4) will fit loosely over the end of the
cable whip until the brass nut is tightened onto the tube reducer fitting.
b. While keeping the cable washer against the tube reducer fitting (6), tighten
the brass nut (2) onto the tube reducer fitting to secure all fittings.
c. Insert the tube reducer fitting into the lug (7) so that the fitting is up against
the end of the machined groove.
d. Tighten the set screw (8) to secure the fitting assembly.

a. Route the cable whip (5) down the back and across the bottom of the
Iso-Flo cabinet against the gray PVC enclosure.
b. Remove the brass thumb screw (1) and lock washer (2) from the bottom of
the shuttle block (3).
c. Align the lug mounting hole (4) to the hole in the shuttle block. Secure the

Power Supply Cable Connection
WARNING: When using a cable with any type of Iso-Flo unit and power supply, do
not set the power supply output voltage to more than 60 kV (60,000 V). Exceeding
60 kV will cause dangerous conditions that may result in equipment damage,
personal injury, or death.
NOTE: Use an electrical contact cleaner in the next step that is safe for use on
printed circuit assemblies and plastic components. The cable end must be
thoroughly dry and free of any residue before installing it. Do not install the cable
until it is thoroughly clean.
1. SeeFigure7.Cleanthepowersupplyendofthecable(1)withaclean,dry,
lint-free cloth.
NOTE: Dielectric oil does not contain PCBs.
2. Locate the small plastic containers of insulating oil or grease supplied with the
power supply. Fill the power supply high-voltage multiplier well (2) with oil or
grease as directed in the power supply manual.
3. Slowly insert the cable end into the power supply well. Wipe up any oil or
grease as it overflows.
4. Secure the cable fitting (3) to the power supply well fitting.
5. Attach the cable to the strain relief (if used) on the cabinet.

Cable Failure Causes
Because the electrostatic cable conducts a high voltage potential, it is subject to
electrical breakdowns, burn through, or carbon tracking if it is not properly cared
for. A major cause of early cable failure is rough usage, such as excessive
whipping of loose cable, bending the cable around a small radius, walking or
driving over the cable, or stretching the cable.
Cable and Power Supply Care
Refer to Table 3. Use these guidelines to obtain maximum life from all components
of an electrostatic system.
Table 3 Cable Guidelines
Do…
Establish a protected path for the cable to follow between the Iso-Flo unit and
the power supply.
Anchor the electrostatic cable so that daily operation does not place strain on
the cable.
When spraying fluids, cover the cable with non-conductive plastic wherever
possible to protect it from contact with solvent and/or coating material. Change
the plastic regularly.
Clean and protect the ends of the cable so that no contaminants, oils, particles,
solvents, etc. are carried into the Iso-Flo unit or power unit where arcing, carbon
tracking, or burn through will occur.
Don’t…
Don’t put dirty (even slightly dirty) cables into the well of the power unit.
Don’t cut or dent the cable while installing it.
Don’t reinstall the cable after maintenance without re-greasing with dielectric
grease (where appropriate).
Don’t bend the cable around a radius of less than 15.2 cm (6 in.) at stationary
points and 20.3 cm (8 in.) at flexing points.
Don’t allow loops or loose segments of the cable between anchor points to flex
severely or strike against other objects.
Don’t anchor the cable to moving machinery unless allowances have been
made for cable movement.
Don’t bundle cables together in such a way that they can strain or abrade
each other.
Don’t use ketones, lacquer thinner, or other active solvents to clean the outside
of the cable as this will damage the outer cover and cause electrical breakdown.
Don’t allow the cable to become cut or abraded around sharp corners.
Don’t walk on the cable or run over it with handling equipment.
