WARNING: TO PREVENT IGNITION OF FLAMMABLE OR

CAUT ION:

COMBUSTIBLE ATMOSPHERES, DISCONNECT POWER FROM
SYSTEM PRIOR TO INSTALLATION OR SERVICE.

Installation must comply with all national, state, and
local codes. Personnel trained in intrinsically safe systems should
only perform installation of this equipment. Improper installation
may result in serious injury or damage. Before proceeding with
installation, read and understand these instructions completely.
The ISS-105-ISO-F Isolated Switch is UL913 listed as an
associated apparatus for interfacing between hazardous and
non-hazardous areas. The ISS-105-ISO-F must be installed in a
non-hazardous area. Follow SymCom's Control Drawing 105 on
the last page of this bulletin 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.

INSTALLATION:

1. Mount the ISS-105-ISO-F in a non-hazardous location on a DIN-rail,
or by installing two #6-#8 screws into mounting holes provided.

2. Connect wiring per SymCom's Control Drawing 105. Follow all
hazardous code requirements while installing wiring to switch input
terminals.

OPERATION:

The ISS-105-ISO-F relay, powered by 120VAC, is an isolated switch
suitable for applications with switch inputs in a hazardous location. In a
powered state, the ISS-105-ISO-F will actuate each output relay within
.75 second of the corresponding input switch closing/opening
(dependent on positive/negative logic mode). Each red LED illuminates
when the corresponding output relay is energized. Each green LED
illuminates when the corresponding input is closed.

CHANNEL INVERT:

The inversion adjustment on the side of the product allows all channels
to be positive or negative logic. Channels cannot be inverted
independently.

Positive Logic:

Invert adjustme nt is fully counte r cloc kwise; the relay will close
when the corresponding input closes.

Negative Logic:

Invert adjustment is fully clockwise; the relay will close when
the corresponding input opens.

Capacitance and inductance of the field wiring from the intrinsically safe equipment to the associated apparatus shall be
calculated and must be included in the system calculations as shown i n the table above. Cable capacitance, Ccable, plus
intrinsically safe equipment capacitance, Ci, must be less than the marked capacitance, Ca (or Co), shown on any
associated apparatus used. The sam e applies for inductance (Lcable, Li and La or Lo, respecti vely). Where the cable
capacitance and inductance per foot are not known, the following values shall be used: Ccable = 60pF/ft., Lcable = 0.2µH/ft.
