Siemens SLIM Loop Isolator Module, Installation Instructions

Installation Instructions SLIM Isolator Module 1 Module Model SLIM Loop Isolator Module from Siemens Industry Inc isolates short on FS 250C analog loops By placing devices between SLIMs during installa a short in the wiring within that group is disconnected from the rest of the loop remainder of the devices continue to operate The SLIM operates in both Class A Class B circuits yellow LED flashes when a device detects a short circuit The SLIM then isolates part of the loop When the short is removed the SLIM automatically restores loop to normal operation The SLIM does not have a loop address and therefore not require address programming nor does it reduce the loop capacity below devices all system power before installation first the battery and then the AC RATINGS Vdc max SLIM is a polarity insensitive module Refer to Figure 1 for the location of the input terminals two output terminals and earth ground Line 1 and Line 2 can be line of the loop Number Line 1 Line 2 Line 1 Line 2 Ground Installation Figure 2 Use a standard 3 1 2 inch deep double gang electrical or a 4 inch square electrical box that is 2 1 8 inches Connect the field wiring Press the SLIM into the box and the module plate to the box Cover the module front plate with the plate supplied and SQUARE with screws supplied Inc Inc Inc Industry Inc Inc TTTTTececececechnologies Di Di Di Division Di SQUARE BOX 1 8 INCHES DEEP GANG BOX 1 2 INCHES DEEP SQUARE 2 the SLIM 315 034904C 3 SLIM may be used in two circuit configurations as follows Figure 3 In Class B wiring each SLIM isolates a branch on the circuit Note that short on the main branch causes the entire loop to fail To prevent this mount the at the enclosure and run each branch independently LOOP 1 2 B All wiring must comply with and local codes order to provide adequate it is recom that you do not more than 20 devices a single SLIM Minimum wire gauge is AWG The total wire resistance wires between SLIMs exceed 20 ohms Do not install more than 15 per FDLC loop All circuits are supervised Refer to the FS 250C P N 315 049589C the list of compatible All terminals are power All wiring must comply with and local codes order to provide adequate it is recom that you do not more than 20 devices a single SLIM Minimum wire gauge is AWG The total wire resistance wires between SLIMs exceed 20 ohms Do not install more than 15 per FDLC loop All circuits are supervised Refer to the FS 250C P N 315 049589C the list of compatible as applicable All terminals are power OUT OUT EARTH OUT OUT OUT OUT 3 Wiring Diagram Class B Installation A Single Loop Figure 4 IIn Class A wiring the SLIMS are wired in series with the loop wiring results in a single continuous loop If any group in the loop has a short that is lost and a Class A circuit failure results ENCLOSURE ANALOG RETURN 2 1 1 2 ANALOG FEED IN OUT OUT IN OUT OUT EARTH IN OUT OUT EARTH 4 Wiring Diagram Class A Installation Single Loop Canada Limited Technologies Division Kenview Boulevard Ontario L6T 5E4 Canada 315 034904C 3
