Panel Mount Enclosure Installation
This document contains drawings, replacementparts lists and instructions for installing panel mount models of920i indicators.
See the 920i Installation Manual, PN 67887, for general installation, configuration and calibration information.
WARNING
The 920i has no on/off switch. Before opening the unit, ensure the power cord is disconnected from the power
outlet.
Use a wrist strap for grounding and to protect components from electrostatic discharge (ESD) when working
inside the indicator enclosure.
This unit uses double pole/neutral fusing which could create an electric shock hazard. Procedures requiring
work inside the indicator must be performed by qualified service personnel only.

Installation
Use the dimensions shown in Figure 1 to lay out the panel cutout for the panel mount enclosure. See Figure 2 for enclosure
dimensions.
Figure 2. Panel Mount Enclosure Dimensions
Once the cutout has been prepared:
1. Insert the enclosure into the cutout from the front of the panel.
2. Install the reinforcing plate on the enclosure from the inside of the panel.
3. Install the clinching bracket on the enclosure from inside the panel.
4. Secure the bracket to the enclosure using the six 1/4" screws provided in the parts kit (PN 71522).
5. Use the nine 1 1/2" screws (PN 82425) to secure the clinching bracket to the panel door.

Grounding
Except for the power cord, all cables routedthrough the cord grips should be grounded against the indicator enclosure.
1. Install the ground clamps on the grounding bar, using the ground clamp screws. Do not tighten the screws at this time.
2. Route cables under cabling bar and through the cord grips and the grounding clamps to determine the cable lengths
required to reach the cable connectors.
Figure 5. Cable Installation with Grounding Clamp
3. Mark the cables to remove insulation and shield. See Stripping Cables on next page.
4. Route stripped cables through the cord grips and grounding clamps.
5. Ensure the shields contact the grounding clamps and tighten the ground clamp screws.
Panel is located between the front bezel and
the reinforcing plate (not shown). The clinch
bracket draws the front bezel against the panel
when screws are tightened.

Stripping Cables
Foil Insulated Cable
Figure 6. Foil Insulated Cable
1. Strip the insulation and foil from the cable 1/2(15 mm) past the grounding clamp.
2. Fold the foil shield back on the cable where the cable passes through the clamp.
3. Ensure the silver (conductive) side of the foil is turned outward for contact with the grounding clamp.
Braided Shielding
Figure 7. Braided Insulated Cable
1. Strip the insulation and braided shield from a point just past the groundingclamp.
2. Strip another 1/2(15 mm) of the insulation to expose the braid where the cable passes through the clamp.
Load Cell Cables
Cut the shield wire justpast the grounding clamp. Shield wire function is provided by contact between the cable shield and the
grounding clamp.
