Installation; Mounting The 220; Load Cell Connection - Cardinal 220 Quick Setup Manual

Before beginning installation of your Model 220 Weight Indicating Instrument, make certain that the
instrument has been received in good condition. Carefully remove the instrument from the
shipping carton and inspect it for any evidence of damage (such as exterior dents or scratches)
that may have taken place during shipment. Keep the carton and packing material for return
shipment if it should become necessary. It is the responsibility of the purchaser to file all claims for
any damages or loss incurred during transit.

Mounting the 220

NOTE! Should your 220 indicator come already installed on a scale, the following information
describing the installation of the instrument does not apply.
The Model 220 Indicator is housed in a NEMA 4X/IP66 stainless steel wall or desk-mount
enclosure. The 220 gimbal may be mounted on a desktop or other smooth, flat, horizontal surface
or may be mounted on a wall. Refer to Figure No. 1 for a layout of wall-mounting bolts.

If wall mounted, make certain the mounting surface is strong enough to support the instrument.
The mounting location should be where the display is easily viewed while being close enough to
provide the operator easy access to the keypad. Carefully lay out the mounting hole locations,
then drill and install the anchor bolts. Attach the gimbal to the wall and securely tighten the
retaining bolts.

Load Cell Connection

cells to the instrument. Failure to do so will result in permanent damage to the
instrument.

loosen the bottom-right cable gland
connector for the load cell. This gland
connector is located on the rear panel
of the enclosure. Refer to Figure No. 2
for illustration of the connector layout.
2. Slip the single cable from the load cell
or load cell junction box through the
gland connector and into the enclosure.
3. Remove 2" of the outer insulation
jacket then remove 1/4" of insulation
