1-4 OPERATION
1-4.1 SAFE PRACTICES
A GROUND AND TEST DEVICE IS A SAFETY-
RELATED DEVICE. IT MUST BE RECOGNIZED
THAT IMPROPER USE CAN RESULT IN DEATH,
SERIOUS PERSONAL INJURY, OR PROPERTY
DAMAGE. THAT IS WHY IT IS MOST IMPORTANT
THAT THE USER DEVELOP SPECIFIC AND SAFE
OPERATING PROCEDURES FOR ITS USE.
The following general safe practices are recommended:
•
The device cannot be stored in a VAC CLAD-
W Breaker compartment. It can only be
stored in a storage compartment.
• Store the device in a clean, dry area free from
dust, dirt, moisture, etc.
• Keep all insulating surfaces, which include pri-
mary support insulation and insulation barriers,
clean and dry.
•
Check all primary circuit connections to
make certain that they are clean and tight.
•
Permit only authorized trained personnel to use
this device.
•
Take extreme care while using this device to
avoid contacting “Live” or “Hot” (energized) ter-
minals.
•
Do not remove the device front panel while
using this device.
•
Always close the grounding switch electrically
from the farthest distance with the remote con-
trol switch.
•
Before inserting the device into the compart-
ment,
correctly identify line and bus termi-
nals for the breaker compartment
and visual-
ly make certain that the selector switch is con-
nected to the desired terminals. Also make cer-
tain that the connected terminals are Bus or
Line as desired.
Typical procedures for use of this device are as follows:
1-4.2 GROUNDING
1.
With the device out of the breaker compartment,
insert the selector switch operating handle and
set the switch for upper or lower terminals as
desired. Remove the handle.
DO NOT ATTEMPT TO OPERATE THE SELECTOR
SWITCH WHEN IT IS ON THE EXTENSION RAILS.
FAILURE TO COMPLY COULD RESULT IN THE
DEVICE COMING OFF THE RAILS CAUSING BODILY
INJURY AND/OR EQUIPMENT DAMAGE.
2. Lift the device and load it on to the extension
rails of the breaker compartment with extreme
care.
3. Push the device to the Test position as indi-
cated by the crisp clicking sound of the levering
latch engaging the levering nut.
4. Using the breaker levering crank, lever the
device to the “Connected” position as indicated
by the red flag appearing in front of and under
the levering crank.
5. Unlock and open the lower test ports
(Selectable Terminals) and test for “dead”
circuit using correctly rated neon test stick or
equivalent.
6. After the circuit is checked “dead” and made
certain that it is maintained “dead”, connect the
remote control switch cable and close the
grounding switch from the safest distance.
7. Padlock the ground switch closed by discon-
necting the control switch cable and sliding the
cover to the left. It may also be locked by an
optional key lock K3,if provided (Figure
3
).
1-4.3 CABLE TESTING
1. With the device out of the breaker compartment,
insert the selector switch operating handle and
set the switch for upper or lower terminals as
desired. Remove the handle.
