Installation
ATTENTION: Electric Shock can cause injury or death.
Remove all power before working on this product.
The drive is at line voltage when connected to incoming AC
power. Before proceeding with any installation or
troubleshooting activity, disconnect, lockout and tag all
incoming power to the drive. Verify with a voltmeter than no
voltage exists at input terminals 181 (L1), 182 (L2) and 183
(L3).
!
❐ 1 Remove and lockout all incoming power
to the drive. Remove the plastic line fuse
cover. The cover is held in place by tabs
inserted in slots and by two screws at the
bottom of the cover.
❐ 2 If drive power has already been installed,
disconnect the incoming power lines from
the drive at AC line terminals 181, 182 and
183 and set the hardware aside for later.
❐ 4 If drive power has not already been
installed, determine whether your wiring
application calls for the existing
compression terminals on the line side of
the disconnect switch, or the AC line bus
bar terminals removed in Step 3.
Each
compression terminal can accept three (3)
wires in the range from 3/0 to 500 MCM.
Each AC line bus bar terminal can accept
up to four (4) user-supplied 1/2 inch ID
wire lugs. If you will be using the AC line
bus bar terminals, you must remove the
compression terminals before mounting
the disconnect switch.
❐ 3 Remove the AC line
terminal connectors by
removing the (6) M12 nuts
as shown. Set the terminals
and nuts aside for
reinstallation later.
