Operation
STEP 5.
To close the disconnect: pull down on the dis-
connect operating lever with a hookstick. See
Figure 20. Closing the disconnect does not close the
interrupter con tacts. The switch must be closed
electrically or by hookstick to close the inter rupter
contacts.
Note:
The switch must be open before opening the discon-
nect, except for vertical-configuration switches or if the “H”
option was specified.
DANGER
The interrupters and terminal pads of a Scada-Mate
Switch may be energized with the interrupters in any
position . Before in specting, servicing, or repairing this
switch or working on the conductors on either side of
the switch, test for voltage using proper high-voltage
test equipment . Then install suitable grounding equip-
ment . Failure to observe these precautions may result
in se rious injury or death .
Emergency Manual Operation
In the event of electrical power loss, a stan dard or extendible
hookstick is used to open and close the interrupters. When the
spring is fully discharged, pull on the operating mechanism
pull-ring with the hookstick seven to nine times to effect a
change of state. If the spring is partially charged, just a single
pull will change the interrupter position. Refer to Figure 21.
