Drive Installation

Drive Accessory Mounting Assure that sufficient cabinet space is available to mount the required drive
accessories. All wiring is to the bottom of the drive. Provide the necessary
clearances for wiring access and wire ways at the bottom of the drive.
Fuse Blocks
The 8510 does not include the incoming AC line fuses inside the drive for
drive component short circuit protection. An optional fuse kit is available
that includes the fuse block and fuses. Make provisions for mounting the
fuse block inside the enclosure. See Figure 3.15 for dimensions of the
optional fuse kits.
Termination Panels
Signal connections to the drive are through multi-pin Honda connectors. If
the optional termination panel assemblies are being used to allow wiring to
terminal blocks, provide sufficient mounting space and wiring access for
these termination panels. A 1.5 m (5 ft.) cable is provided to connect the
termination panel to the drive. See Figure 3.16 for dimensions of the
termination panels. The DIN #3 mounting rail is not provided with the
termination panels. Use Allen-Bradley type 199-DR1 or equivalent
mounting rail. Depending on the system configuration, the termination
panels required will vary from one 50 pin and one 20 pin to one 50 pin and
as many as four 20 pin units.
Removal of Drive Cover The front cover of the drive is mounted via two locating pins in the upper
corners and two captive retaining screws in the bottom corners.
To remove the cover, loosen the two retaining screws and pull the bottom
of the cover outward until the cover is clear of the drive bottom. Next, lift
the cover upward until the locating pins are removed from the locating
holes on the top of the drive. It may be necessary to remove one or more of
the Honda connectors to obtain the necessary clearance at the bottom of the
cover.
To replace the cover, hold it with the bottom tilted slightly away from the
drive. Engage the cover locating pins into the holes on the top of the drive
and carefully swing the bottom toward the drive. Assure that the two
guides on the sides of the drive near the bottom of the cover are both inside
the cover.
Important: The top edge of the hole for the programming display may hit
the top of the display bezel. Do not force the cover backward to its final
position or it will bend and possibly damage the I/O Board. Push upward
on the bottom of the cover until the edge of the hole clears the top of the
bezel. It may be necessary to gently pull downward on the edge of the
bezel while pushing upward on the cover to make the cover clear the top of
the bezel. When the display bezel is properly located, tighten the two
retaining screws in the bottom of the cover.
