920i® Programmable HMI Indicator/Controller
Panel Mount Enclosure Installation
This document contains drawings, replacement parts lists and instructions for installing panel mount models of 920i 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 enclosure, ensure the power cord is disconnected from the
power outlet. Power outlet must be located near the product.
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.
IMPORTANT: Use a wrist strap for grounding and to protect components from electrostatic discharge (ESD) when working
inside the indicator enclosure.

Installation
Use the dimensions shown in Figure 1 on page 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 panel mount enclosure into the cutout from the front of the panel.
2. Slide the reinforcement plate on the enclosure from the inside of the panel.
3. Install the clinching bracket on the enclosure on the inside of the panel.
4. Secure the clinching bracket to the enclosure using the six 1/4" screws provided in the parts kit.
5. Use the nine 1 1/2" screws, provided in the parts kit, to secure the panel mount enclosure to the panel.

Panel is located between the front bezel and the reinforcing plate (not shown).
The clinching bracket draws the front bezel against the front side of the
panel when screws are tightened, while pressing the
reinforcing plate against the backside of the panel.

Grounding
Except for the power cord, all cables routed through 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 4. 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.
Stripping Cables
Foil Insulated Cable
Figure 5. 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 6. Braided Insulated Cable
1. Strip the insulation and braided shield from a point just past the grounding clamp.
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 just past the grounding clamp. Shield wire function is provided by contact between the cable shield and the
grounding clamp.
