10 480 Legend Series
2.0 Installation
2.1 Unpacking
Immediately after unpacking, visually inspect the 480 to ensure all components are included and undamaged. The
shipping carton should contain the indicator, this manual, and a parts kit. If any parts were damaged in shipment,
notify Rice Lake Weighing Systems and the shipper immediately.
See Section 2.8 on page 18 for parts kit contents.
2.2 Enclosure Disassembly
The indicator enclosure must be opened to connect the scale load cell cable and any other interface connection.
Before opening the unit, ensure the power cord is disconnected from the power outlet.
Ensure power to the indicator is disconnected, then place the indicator face-down on an anti-static work mat.
Remove the screws that hold the backplate to the enclosure body. Then lift the backplate away from the enclosure
and turn it over to access boards.
The display cable will still be attached. Be careful when lifting and turning over the backplate so it does
not become damaged or dislodged.
2.3 Cable Connections
The 480 provides four cord grips for cabling into the indicator: one for the power cord, three to accommodate load
cell, communications, digital inputs and outputs, and analog output cables. Two of the three free cord grips come
with a plug installed to prevent moisture from entering the enclosure. Depending on the application, remove the
plug from any cord grip that will be used and install cables as required. Figure 2-1 shows the recommended
assignments for the
480 cord grips.
Figure 2-1. Recommended Cord Grip Assignments
When installing cords through cord grips, ensure the cord grip is tightened snuggly to prevent moisture
from entering the enclosure.
