INSTALLATION

Top View

After the base unit is installed in the panel, the option module can be attached to the
back of the instrument. Orient the module so that terminals A, B. C and D are on
top. Slide the module on to the back of the instrument so that the tabs on the module
fit underneath the grooves on the top of the instrument and above the grooves on the
bottom. The two pieces will fit together tightly enough so that the instrument will
support the weight of the module during wiring. Terminals 1 - 8 on the module

Tabs

connect through to the base unit (Refer to the Technical Manual of the instrument
for corresponding functions and specific wiring instructions). Provided with the
module are 8 long screws and up to 8 short screws. The long screws provide the
connections for terminals 1- 8, and as secure the module to the instrument. The
short screws are for wiring terminals A through E, which are the functions of the
option module.

AC Power

For 115 VAC power, connect the Line from the
source to terminal E and the Neutral to H.
Jumper H to F and G to E so that the inputs are
in parallel. For 230 VAC connect the inputs so
they are in series with the Line to E and the
Neutral to H, then jumper terminals G and F.
