DISCONNECT SWITCH AND FUSE BLOCK KIT
INSTALLATION INSTRUCTIONS
Unfused and Fusible Disconnect Switches
1.
Remove nuts
and washers from flange plate.
2. Place the disconnect switch into the enclosure with
the operating handle in the “Off” position. Tilt the
assembly under the flange and at the same time
bring the handle through the slot provided.
3. Place flange plate studs through the holes in the
flange and mechanism frame while holding the
assembly against the under side of flange. Secure
assembly to flange.
4. Attach disconnect switch firmly to the enclosure
mounting plate surface. See line drawing Page 2
(Mounting hardware and spacers are furnished by
user).
Fusible Disconnect Switches Only
1.
Attach fuse clips provided with the fuse block adap-
ter plate kits to the disconnect switch terminals. For
100, 200 and 400 Amp clips see Form 1494F-01A.
2. Attach the fuse block adapter plate to the disconnect
switch mounting bracket.
3. Secure the fuse block adapter plate to the enclosure
mounting plate surface. See line drawing Page
(Bolts and spacers are furnished by user).
NOTE:
It is recognized that holes in the enclosure
mounting plate surface used to secure the discon-
nect and fuse block adapter plate can be located
previous to installation. Refer to line drawings on
Page
