Rice Lake Tracer AVi - v2.0 - Manual (Page 6)

2 Tracer AVi Installation Manual
2.0 Installation
This section describes procedures for connecting load
cell, power, and serial communications cables to the
iQube TM enclosure. Drawings and replacement parts
lists are included for the service technician.
Use a wrist strap to ground yourself and
protect components from electrostatic
discharge (ESD) when working inside the
iQube enclosure.
Disconnect AC power from the main module before installing
remote displays.
2.1 Unpacking and Assembly
Immediately after unpacking, visually inspect the
contents to ensure all components are included and
undamaged. The shipping carton should contain the
iQube , the remote display, and connection cables. If
any parts were damaged in shipment, notify Rice Lake
Weighing Systems and the shipper immediately.
See Table 2-4 on page 4 for information on the iQube
cables.
2.2 Enclosure Security/Disassembly
After an NTEP inspector has examined the unit, he/
she will install security cables pictured in Figure 2-1.
These cables prevent the
Tracer AVi from being
tampered with by an unauthorized individual. If these
cables are removed, NTEP certification will become
void.
If the Tracer AVi enclosure must be opened by an
authorized technician, ensure power is disconnected,
then place it on an anti-static work mat. Cut the
tamper-proof cables, remove screws, and remove the
enclosure’s cover. An NTEP inspector will have to
examine the unit and attach new security cables.

connector, two remote display connectors, one host
(PC) com port connector for connecting to the PC
running
VIRTUi , and an AC power cord.
2.5 Load Cells
