8. Wiring Diagram:
Typical wiring configuration for E.R.S MINI Edition
1:
Terminate the Live, Neutral and Earth conductor of the pre wired POWER IN cable/connector to
the load side of the 20A double pole isolation switch.
2:
Run a 16A supply circuit using 2.5mm cable to the supply side of the 20A double pole
isolation switch.
3:
Terminate the Live conductor of the pre wired POWER OUT cable/connector to supplied push fit
through connector located inside the distribution board
(G)
4:
Terminate the immersion or load circuit to be driven by ERS into the remaining side of the sup-
plied push fit connector inside the distribution board
(G)
5:
Terminate the Neutral and Earth conductors of the pre wired POWER OUT cable/connector to the
respective Neutral and Earth bars within the distribution board.
NOTE: It is essential that there are no other loads or electrical connections other than
resistive heating element connected to the ERS driven circuit. Failure to observe this will
result in damage.
IMPORTANT
IMPORTANT
It is essential that the current clamp (CT) is connected between the main (primary) dis-
tribution board and the building
’
s supply meter and has been positioned the correct way.
Observe the silver label on the CT for correct fitment.
It must be connected in this location in order for ERS MINI to function correctly. Failure
to observe this will result in incorrect operation which may result in energy import.
PowerFlow will not be responsible for any costs incurred by incorrect installation.

Note: the current clamp is pre wired
with 3 meters of twisted pair cable.
This can be extended if required by
using standard CAT5e data cable up to
100 meters. Use one pair only.
