Mounting the SLIM
P/N 315-034904C-3
The Model SLIM Loop Isolator Module from Siemens Industry, Inc. isolates short
circuits on FS-250C analog loops. By placing devices between SLIMs during installa-
tion, a short in the wiring within that group is disconnected from the rest of the loop.
The remainder of the devices continue to operate. The SLIM operates in both Class A
and Class B circuits.
A yellow LED flashes when a device detects a short circuit. The SLIM then isolates
that part of the loop. When the short is removed, the SLIM automatically restores
the loop to normal operation. The SLIM does not have a loop address and therefore
does not require address programming nor does it reduce the loop capacity below
252 devices.
Remove all system power before installation, first the battery and then the AC.
Voltage: 24 Vdc
Current: 1mA max
The SLIM is a polarity insensitive module. Refer to Figure 1 for the location of the
two input terminals, two output terminals and earth ground. Line 1 and Line 2 can be
either line of the loop.

4 Out — Line 2
5 Earth Ground
Mechanical Installation
• Use a standard 3 1/2-inch deep, double gang electrical
switchbox or a 4-inch square electrical box that is 2 1/8 inches
deep.
• Connect the field wiring. Press the SLIM into the box and
fasten the module plate to the box.
• Cover the module front plate with the plate supplied and
