Installation/Wiring
1. For Cat. # 20MD414, install two clevis clamps into the drive to serve as
lifting points. Two 9/16-inch through holes are machined into the casting
protrusions.
For Cat. # 20MD500 or 20MD643, install two eyebolts into the drive to
serve as lifting points. Two 3/4-inch nuts are welded to the drive’s
baseplate. Screw two eyebolts (2-inch eye I.D., 6-inch long shank) into
the nuts.
For Cat. # 20MD1K2, install two clevis pins into the drive to serve as
lifting points. Two 1-inch through holes are provided in the sheet metal
chassis.
2. For Cat. # 20MD414, 20MD500 or 20MD643, connect 18 inches
(nominal) of chain between the eyebolts or attached clevis clamps and
secure them with a clevis clamp.
For Cat. # 20MD1K2, connect 50 inches (nominal) of chain between the
eyebolts or attached clevis clamps and secure them with a clevis clamp.
3. Using an overhead or portable hoist (minimum 1/2-ton rated capacity),
attach a free-fall chain to the chain secured to the drive. Take up any
vertical slack in the chain.
4. Using the hoist, lift the drive from the horizontal shipping pallet.
5. Position the drive in the enclosure.
6. For Cat. # 20MD414, 20MD500 or 20MD643, attach the drive to the
vertical surface selected using the four (4) mounting holes provided.
For Cat. # 20MD1K2, attach the drive to the vertical surface using the
six (6) mounting holes provided.
In order to maintain a flat mounting surface and to ensure that bolt
tightness is maintained, use flat washers and split-ring lock washers
under the bolt heads. Refer to
Table 1.B
and
Figure 1.5
or
for drive mounting dimensions.
7. For Cat. # 20MD500 or 20MD643, remove the eyebolts and the chain
between them.
For Cat. # 20MD414 or 20MD1K2, remove the clevis clamps and chain
between them.
Verifying the Drive’s Watts Loss Rating
When mounting the drive inside of an enclosure, you should determine the
watts loss rating of the drive from
. This table lists the typical full
load power loss watts value at 2 kHz (rated carrier frequency). Ensure that
the enclosure is adequately ventilated with 0
°
to 40
°
C ambient air based on
the drive’s watts loss rating.
