Section 2: Installation of IZM cassette
cell switch
A #2 Phillips head screwdriver is recommended for this installation.
To install the IZM cassette cell switch, proceed with the following
five steps:
Step 1:
Three sets of 12 wire markers are included with each
switch assembly, allowing it to be marked for either the
C
,
T
, or
D
position. Depending upon the number and location of the switches
to be used, apply the appropriate labels near the ends of the leads.
Unused labels may be discarded.
Figure 2. Step 1
Step 2:
Bend the gasket 90 degrees at the crease line. Fasten it
in place between the outside wall of the cassette and the gasket
bracket with four M6 x 10 mm thread-forming screws. A right-side
mounting is shown. Bend the gasket the opposite way for a left-
side mounting.
Figure 3. Step 2
Step 3:
Insert cell switch into desired position by first sliding
the lock to the unlocked (up) position. Install the hook feet down
through openings, then slide switch forward so hook feet engage
the cassette’s side wall. Slide the lock down into the locked position.

Step 4:
Terminal blocks should be located at the end of each row,
and should have the appropriate labels (C, D, or T, and 1 through 6,
and 7 through 12) on them. Use the blank labels supplied with the
terminal blocks for identification.
Wire the switch to these terminal block locations per the markings
on the switch wires. Switch leads are terminated with “fast-on”
connectors that will plug into the rear of the terminal blocks
as shown.
Figure 5. Step 4
Step 5:
If applicable, each additional switch (maximum of three)
requires two terminal blocks or can be wired to an external source.
Electrical accessories, such as a UVR, shunt trip or auxiliary
switches, may limit the number of switches that can be connected
to the breaker’s terminal block. If this is the case, the customer
must supply an external terminal block.
