Warnings
WARNING! An electric shock can be fatal; electrical connection work may only be carried out by a competent
person
The earth conductor must be correctly installed and reliably connected
This device must be equipped with an over-current protection device of maximum 16 Amps (B16)
Only purely resistive loads must be connected to the Heater output terminals

Overview Diagram
The diagram on the following page gives an overview of the basic wiring with respect to the grid supply and the
microgeneration system.
Also refer to the
Application Examples
(page 31) for full wiring schematics.
Supply
The eddi device should be connected to a single-phase 230V or 240V nominal AC supply. The supply should be from a
dedicated 16A circuit breaker, or it can be from a hard-wired 13A fused spur outlet if the heater load is less than 3kW.
Heater Loads
Most purely resistive heaters can be used with eddi, examples include immersion heaters, storage heaters, convection
heaters and underfloor heating mats. Refer to the Application and Examples section for wiring diagrams using different
heater types. Whichever heater type is used, the following criteria must always be observed:
•
One or two purely resistive loads may be connected (Note: only one is live at any one time)
•
Maximum rating of each load is 3.68kW
•
Minimum heater rating is 150W
•
Resistive loads only
•
Heater Neutral conductor must be connected to heater output N terminal
•
No electronic controls to be connected to Heater terminals; mechanical thermostats only
•
No timers to be connected to Heater terminals, including mechanical timers
Cable Clamps
If using flexible cables or cables not secured by other means, the cable clamps must be used to secure the supply and
heater cables.
