4 IQ 700 Installation Manual
2.0 Installation and Wiring
This section describes the procedures for connecting load cell and serial communications cables to the IQ 700
indicator. Instructions for CPU board replacement are included, along with assembly drawings and parts list for the
service technician.
Use a wrist strap to ground youself
and protect components from
electrostatic discharge (ESD) when
working inside the indicator.
2.1 Unpacking and Assembly
All indicators are configured and tested prior to
shipment to ensure that they are fully functional.
Immediately after unpacking, visually inspect the IQ
700 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.
2.2 Enclosure Disassembly
The indicator enclosure consists of a load cell
connector and cord grips for communication cables.
The enclosure must be opened to connect the
communication cables.
The IQ 700 has no on/off switch.
Before opening the unit, ensure the
power cord is disconnected from the
power outlet.
Ensure power to the indicator is disconnected then
remove the screws that hold the enclosure body. Place
the indicator face-down on an antistatic work mat, then
lift the enclosure away from the front bezel. Set the
enclosure aside.
2.3 Cable Connections
The IQ 700 provides a load cell connector and three
cord grips for cabling into the indicator; one for the
power, two to accomodate communications, digital
input, and analog output cables.
One of the two free cord grips comes with a plug
installed to prevent moisture from entering the
enclosure. Depending on your application, remove the
plug from the appropriate cord grip and install cables as
required.
Figure 2-1 shows the recommended assignments for the
IQ 700.
