Caution
Discontinued Product
• Use a wrist strap to ground yourself and protect
components from electrostatic discharge (ESD) when
working inside the indicator enclosure.
• This unit uses double pole/neutral fusing which could
create an electric shock hazard. Procedures requiring
work inside the indicator must be performed by
qualified service personnel only.
• The supply cord serves as the power disconnect for the
IQ plus 710. The power outlet supplying the indicator
must be installed near the unit and be easily accessible.
2.1

Unpacking and Assembly

Immediately after unpacking, visually inspect the IQ
plus 710 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 and identification labels.
• Two 8-32NC x 7/16 fillister head screws (PN
30623). These screws occupy the holes above
and on either side of the setup screw on the
indicator backplate (see Figure 2-5 on page 8).
• Ten 8-32NC x 3/8 machine screws (PN 14862)
f o r t h e i n d i c a t o r b a c k p l a t e ( s e e # 2 9 i n
Figure 2-9 on page 13).
• Twelve bonded sealing washers (PN 45042) for
backplate screws included in the parts kit.
• Four cord grip reducing glands (PN 15664).
• Four rubber bumpers ("feet") for the tilt stand,
PN 42149.
• 6-position screw terminal (PN 70599) for
connector J1; two 7-position screw terminals
(PN 70600) for connectors J4 and J12; two
10-position screw terminals (PN 70601) for
connectors J7 and J8.
• One kep nut (PN 14676) for grounding cable
shield wires against the backplate.

Enclosure Disassembly

The indicator enclosure must be opened to connect
cables for load cells, communications, digital inputs,
digital outputs, and analog output.
The IQ plus 710 has no on/off switch.
Warning
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 antistatic work
mat. Remove the screws that hold the backplate to the
enclosure body, then lift the backplate away from the
enclosure and set it aside.
NOTE: With the backplate removed, check the battery to
ensure it has not been jarred loose from the battery holder
(B1) in shipping.
2.3

Cable Connections

The IQ plus 710 provides five cord grips for cabling
into the indicator: one for the power cord, three to
accommodate communications, digital I/O, and
analog output cables, and one metal cord grip for the
load cell cable. The three nylon cord grips come with
a plug installed to prevent moisture from entering the
enclosure. Depending on your application, remove the
plug from any cord grip that will be used and install
cables as required.
Except for the power cord and load cell cables, all
cables routed through the cord grips should be
grounded to the ground stud on the indicator
backplate.
2.3.1

Load Cells

To attach cable from a load cell or junction box, use
the following procedure to cable through the metal
cord grip:
1. Disconnect indicator from power source.
2. Place indicator face-down on an antistatic work
mat. Remove screws that hold the backplate to
the enclosure body.
3. Loosen cord grips, then route cables through the
stainless steel cord grip. Determine cable length
required to reach connector J1. Mark the cable at
the inside edge of the cord grip (see Figure 2-1
on page 5).
