REPLACING THE BATTERY

A 3.0V Lithium battery on the power supply / display board maintains the
real-time clock and protects the system RAM when the IQ plus
not connected to the AC power line. Under normal circumstances, the
battery lasts about three years. We recommend replacement every two years,
or anytime the situation warrants it.

INSTALLING A REMOTE SUPERVISOR SWITCH

The optional supervisor switch allows you to access the SETPNT configura-
tion menu without opening the case. To install a remote switch, remove the
jumper block from J8 on the CPU board. Connect the remote switch wires to
J8 at the two terminals closest to the setup switch, SW1. The supervisor
mode switch operates independently from SW1.

WALL MOUNTING SS AND HE MODELS

If you are permanently mounting an SS or HE model to the wall,
Underwriter's Laboratory (UL) requires that you run the AC power cord in
conduit and connect it to the case with a conduit hub according to standard
construction practices. For portable units, the standard power cord is
sufficient.
Figure 2-6 shows a typical method for mounting the indicator which
maintains its portability. Use the installation screws to secure four #10 wall
anchors. Then, remove the installation screws and attach the indicator with
four threaded eye bolts.
