Installation Instructions for
ISS-101 Isolated Switch
WARNING:TO PREVENT IGNITION OF FLAMMABLE OR COMBUSTIBLE
ATMOSPHERES, DISCONNECT POWER FROM SYSTEM PRIOR
TO INSTALLATION OR SERVICE.
CAUTION: Installation must comply with all national, state, and local codes.
Installation of this equipment should only be performed by personnel trained in
intrinsically safe systems. Improper installation may result in serious injury or
damage. Before proceeding with installation, read and understand these
instructions completely.
The ISS-101 Isolated Switch is UL913 listed as an associated apparatus for interfacing
between hazardous and non-hazardous areas. The ISS-101 must be installed in a
non-hazardous area. Follow SymCom's Control Drawing 101 on the back of this sheet for
proper installation.
All wiring connected to a hazardous location must be separated from all non-intrinsically
safe wiring. Description of special wiring methods can be found in the National Electrical
Code ANSI/NFPA 70, Article 504 Intrinsically Safe Systems. Check your state and local
codes for additional requirements.
WARNING: REMOVE POWER FROM SYSTEM PRIOR TO INSTALLING OR SERVICING
THE ISS-101 RELAY.
Installation:
1.Mount the ISS-101 in a non-hazardous location on a DIN-rail, or by installing two #6-#8
screws into the octal base mounting holes provided.
2.Connect wiring per SymCom's Control Drawing 101. Follow all hazardous code
requirements while installing wiring to switch input terminals 1 and 8.
Operation:
The ISS-101 relay is powered with 115VAC and is designed as an isolated switch suitable
for applications with switch inputs in a hazardous location.In a powered state, the ISS-101
will close its output relay when the input switch is closed.The green LED on the cover will
illuminate when the relay is energized and extinguish when the relay is de-energized.
