Installation & Wiring
1. The ISO Series Intrinsically Safe relays are UL913 Listed as associated apparatus for interfacing between hazardous and safe areas. The
ISO relay must be installed in a suitable enclosure in a safe area.
2. For DIN-rail mounting, snap the relay on 35mm DIN track. For panel mounting, first remove both terminal connectors from the safe and hazardous
sides. Then, using a thumb, gently extend the two black DIN-rail clips from under the relay until they snap into place and the mounting hole on each
one is vis ble. Mount the relay to the panel using a #8 screw through the hole on each clip.
3. Connect all wires to the device per Macromatic Control Drawing ISD1A04 (on back). The safe (black) and hazardous (blue) terminal connectors
are removable for easier wiring and keyed to prevent incorrect wiring. Use #14-24 solid or stranded copper wire with a terminal tightening torque of 7 in-lbs.
If terminal connectors were removed, be sure to fully reinsert the terminal connectors into the proper color-coded receptacle on the device.
Operation
The ISO Series relay consists of four intrinsically safe inputs and corresponding electromechanical relay outputs for each. There are also nine LEDs for
status indication as defined below.

Troubleshooting:
If the unit fails to operate properly, check that all connections are correct per Control Drawing ISD1A04. If the V LED flashes Red
continuously, the device has been damaged and must be replaced.
Warranty:
All catalog-listed ISO Series Intrinsically Safe Relays manufactured by Macromatic are warranted to be free from defects in workmanship or
material under normal service and use for a period of five (5) years from date of manufacture.
