2.8 REPLACING THE CASE
Before installing the case, check the following:
• All cables dressed and securely connected.
• Jumpers JP1 and JP2 installed or removed correctly for your application.
• Chassis cleaned of cut-off wires and insulation.
• Capacity strip properly installed and tabs folded away from gaskets.
Install the case as follows:
(1)
Slide the case onto the unit,
being careful that the ca-
pacity label does not inter-
fere with the gasket seal.
(2)
Install one drilled standoff at
position 6 in Figure 10 and
hex and/or cap nuts at all
other positions. The stan-
dard model has 4 threaded
studs; the NEMA 4 model
has 14.
(3)
For the standard model,
tighten cap nuts and stand-
off slightly to compress the gaskets.
(4)
For the NEMA 4 model, use the tightening sequence shown in Figure 10. Using #8-32
small pattern hex nuts on locations 1-5 and 7-14 and the drilled standoff at 6, tighten the
hex nuts and standoff by small increments so the gasket compresses evenly. To assure
a watertight seal, tighten the hex nuts and standoff to a final torque value of 4 lb-in. After
completion of the final torque sequence, install the cap nuts on locations 1-5 and 7-14 to
a torque of 4 lb-in.
2.9 MOUNTING THE INDICATOR
The IQplus 310A may be flush-mounted in a panel or wall using the Panel Mounting Accessory
Kit (#19351), or mounted on a bench or wall using the Wall/Bench Mounting Accessory Kit
(#19350). This section describes both methods of mounting, beginning with the panel mounting
procedure.
2.9.1 PANEL MOUNTING PROCEDURE
To mount the IQplus 310A into a panel, choose the location then proceed as follows:
(1)
Make a 7 3/8" W x 4 1/2" H cutout in the panel.
(2)
Remove the AC cable from the unit.
(3)
Remove the case of the indicator. Refer to Section 2.3.
(4)
Feed the load cell and communications cables through the panel cutout and then
through the rear of the case.
(5)
Connect the cables to the indicator according to Sections 2.5 and 2.6.
(6)
Reassemble the indicator in the case. Refer to Section 2.8.
(7)
Insert the indicator into the panel from the front and temporarily hold it in place.
