Drive Installation
Chapter 5
5-44
ATTENTION: The installation of the drive must be planned
such that all cutting, drilling, tapping and welding can be
accomplished with the drive removed from the enclosure. The
drive is of the open type construction and any metal debris must
be kept from falling into the drive. Metal debris or other foreign
matter that becomes lodged in the drive circuitry frequently
results in significant drive damage when power is applied.

Enclosure Wall (through-the-wall) Mounting
The following procedure provides the steps needed to properly mount the
8510 through the enclosure wall.
1. Locate the area that the drive is to be mounted, leaving at least 75 mm
(3 inches) of clearance on all sides and 150 mm (6 inches) on the top.
2. Prepare the enclosure using the panel cutout information provided in
Chapter 3. All holes must be deburred inside and outside the enclosure.
Remove any sharp edges that may be present around the cutout.
3. Unfold the gasket and position (paper side toward drive) around the
drive. Remove the protective paper from the adhesive on the top side of
the gasket. Carefully align the gasket holes with the drive mounting
holes and press the gasket into place. Repeat this procedure for the
remaining sides. See Figure 5.1.
4. Securely bolt the drive (and gasket) into the enclosure. Use 6 mm (or
1/4 in.) bolts with lockwashers. Alternately tighten the nuts to assure
uniform compression of the sealing gasket. Torque to 5.5 N-m (50
lb.-in.).
To assist in handling larger size drives, there are holes on the sides of
the drive that can be used to attach lifting hooks from a properly rated
lifting device. The lifting hooks should extend no more than 12.5 mm
(0.5 in.) inside the drive or they may damage internal drive
components.
ATTENTION: To guard against drive damage and/or personal
injury when using a lifting device, assure that the device is
operated per manufacturers instructions.

ATTENTION: During heavy regenerative load operations, the
flat metal resistor element attached to the back of the heat sink
may become very hot (in excess of 125
°
C or 257
°
F) and could
cause burns if touched. Use of the heat sink cover described
below and shown in Figure 5.2 would help guard against
accidental touching of this resistor.
