Tracer AV Installation Manual - Installation 3
2.0 Installation
This section describes the connections between the DB-9 plugs and the CPU board. This section also includes
assembly drawings, connection tables, 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 Tracer AV enclosure.
• This unit uses line fusing which could create an electric shock hazard. Procedures requiring work inside
the
Tracer AV enclosure must be performed by qualified service personnel only.
• The supply cord serves as the main power disconnect for the Tracer AV. The power outlet must be
installed near the unit and be easily accessible.
2.1 Unpacking and Assembly
Immediately after unpacking, visually inspect the Tracer AV to ensure all components are included and
undamaged. The shipping carton should contain the Tracer AV enclosure, remote display, remote keypad, this
manual, two cables, and a power cord. If any parts were damaged in shipment, notify Rice Lake Weighing
Systems and the shipper immediately.
2.2 Enclosure Security/Disassembly
After an NTEP inspector has examined the unit, he/she will install security cables pictured in Figure 2-1 and
Figure 2-2. These cables prevent the
Tracer AV from being tampered with by an unauthorized individual. If these
cables are removed, NTEP certification will become void.
If the Tracer AV enclosure must be opened by an authorized technician, ensure power is disconnected, then place
it on an anti-static work mat. Cut tamper-proof cables, remove screws, and remove the enclosure’s top cover. An
NTEP inspector will have to examine the unit and attach new security cables.
