Wiring
Note:
WARNING
This unit should be installed in a restricted access location where access can only be
gained by service personnel or users who have been instructed about the reasons for the
restrictions applied to the location and about any precautions that shall be taken; and
access is through the use of a tool or lock and key, or other means of security, and is
controlled by the authority responsible for the location.
All equipment must be installed according to the applicable country wiring codes.
Note:
The Electric Utility series of IOLAN units do not have a power switch, and an
appropriately rated circuit breaker must be installed externally to the unit. If two power
sources are used, each source must have a circuit breaker. As a safety precaution you
should not rely upon the unit's front panel LEDs as a power indicator.
For power and relay wiring, the use of ring terminals size #6 (M3.5) is recommended using stranded
wire size AWG 18-14. Tighten all screws to a torque of 12 Lb-in (1.36 Nm).
Grounding
The Electric Utility series of IOLAN units have a chassis ground screw. This connection must be
connected to "Equipment Ground" for DC installations or "Safety Ground" for AC installations. A
second “earth ground” connection is provided for secondary grounding. This should only be used in
conjunction with the grounding screw provided on the terminal connector.
For “ground” the use of ring terminal size #8 (M4) is recommended using stranded wire size AWG 18-
14. Tighten screw to a torque of 12 Lb-in (1.36 Nm).
Note:
For your safety, before attempting to connect or modify any of the electrical connections
to the unit, please be sure all wiring is disconnected from any live power source. Power
should only be applied when you are sure that the wiring is correct and any safety covers
are properly installed.
