2.0 Installation
This section describes procedures for connecting load
cell and serial communications cables to the IQ plus
590-DC indicator. Instructions for battery and CPU
board replacement are included, along with assembly
drawings and parts lists for the service technician.
Use a wrist strap to ground yourself and
protect components from electrostatic
discharge (ESD) when working inside
the indicator enclosure.
2.1 Unpacking and Assembly
Immediately after unpacking, visually inspect the IQ
plus 590-DC to ensure all components are included
and undamaged. The shipping carton should contain
the indicator with attached tilt stand, this manual, and
a parts kit. If any parts were damaged in shipment,
notify Rice Lake Weighing Systems and the shipper
immediately.
The parts kit contains the items listed below:
• Capacity, annunciator, and identification
labels. The annunciator label (PN 53374)
provides replacement overlay decals for the
displayed units annunciators.
• 3-position (PN 15888) and 7-position (PN
23165) pluggable terminal blocks for load cell
and serial communications connectors.
• One 8-32NC x 7/16 fillister head screw (PN
30623). This screw occupies the hole below
the setup switch access screw on the indicator
backplate (see Figure 2-4 on page 7).
• Two 8-32NC x 3/8 machine screws (PN
14862) for the indicator backplate (see #10 in
Figure 2-7 on page 10).
• Five neoprene washers (PN 45042) for
backplate screws included in the parts kit.

if necessary. Place the indicator face-down on an
antistatic work mat. Remove the screws that hold the
backplate to the enclosure body, then lift the backplate
away from the enclosure. Disconnect battery cable to
connector J3, then set the backplate assembly aside.
