Rice Lake 820i User manual

820i™Programmable HMI Indicator/Controller
Panel Mount Enclosure Installation Instructions
This document contains drawings, replacement parts lists, and instructions for installing panel mount models of
820i indicators. See the 820i Installation Manual, PN 93018, for general installation and configuration and
calibration information.
WARNING
The 820i 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.
The supply cord serves as the power disconnect for the 820i. The power outlet supplying the indicator
must be installed near the unit and be easily accessible.

Once the cutout has been prepared, slide the enclosure into the cutout from the front of the panel. Slide the
clinching bracket around the enclosure from inside the panel. Secure the bracket to the enclosure using the six 1/4"
screws provided in the parts kit (PN 94435), then use the nine 1-1/2" screws (PN 82425) to secure the clinching
bracket to the panel door. See Figure 3.

3.2 Cable Grounding
All cables routed into the panel mount enclosure should be grounded against the indicator enclosure. Do the
following to ground shielded cables:
•Use the lockwashers, clamps, and kep nuts provided in the parts kit to install grounding clamps on the
enclosure studs adjacent to cord grips.
Insulated cable
Foil (silver side out) Grounding clamp
Shield wire (cut)

Figure 5. Cable Installation with Grounding Clamp
• Route cables under cabling bar (see Figure 5) and through grounding clamps to determine cable lengths required
to reach cable connectors. Mark cables to remove insulation and shield as described below:
• For cables with foil shielding, strip insulation and foil from the cable half an inch (15 mm) past the
grounding clamp (see Figure 4). Fold the foil shield back on the cable where the cable passes through the
clamp. Ensure silver (conductive) side of foil is turned outward for contact with the grounding clamp.
• For cables with braided shielding, strip cable insulation and braided shield from a point just past the
grounding clamp. Strip another half inch (15 mm) of insulation only to expose the braid where the cable
passes through the clamp.
• For 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.
• Route stripped cables under cabling bar and through the clamps. Ensure shields contact grounding
clamps. Tighten grounding clamp nuts.
• Use cable ties to secure cables to cabling bar.
