The electrical installation must be large enough for a protected output with 63 A gl/gG fuses to be available for the XRGI sys-
tem. With multi-module systems, each XRGI system must have its own output.
The Power Unit can modulate its electrical output to meet the property's current electricity consumption, and only generate
electricity at the current purchase price, and not feed it into the grid.
To achieve the power-controlled function, the electrical connection must be made at a supply point in the main control cabi-
net behind the main meter, and an additional reference meter must be installed behind this supply point and upstream of the
electrical loads.
In properties which always use more electricity and heat than the Power Unit can produce, or where the sales price for electrici-
ty is equal to or greater than the purchase price, the XRGI system can be connected at any sufficiently dimensioned connection
point without a reference meter.
Any electricity feed-in must be reported to the network operator before commissioning the XRGI system.
The IQ-Control Panel is equipped with grid monitoring relay according to DIN VDE 0126-1-1, and is used to replace the "con-
trol point with separator function accessible at any time".
(See also circuit diagram for electrical connections – Annexe 1)
The electrical installation consists of the following steps:
Install the supply point: a protected output immediately behind the electricity meter (utility company's meter), upstream of
the reference meter and all other outputs.
Install the reference meter (electronic meter with pulse output, provided by EC-Power A/S) downstream of the supply point
and upstream of all other outputs.
Option: connect the current converter to the reference meter if the feed line safety is > 80 A.
Option: create groups for each heat pump and/or each heating cartridge.
Mount the IQ-Control Panel.
Lay supply, signal and control cables between the units as follows:
Power supply cable from supply point to IQ-Control Panel
Signal cable from reference meter to IQ-Control Panel
Signal cable from Q60-Heat Distributor to IQ-Control Panel
With existing storage tanks: introduce the PT 100 sensors in four immersion sleeves for 6 mm immersion sensor and fit
them in the storage tank.
Fit a 230 V AC socket for the Q60-Heat Distributor if there is not one already.
Lay a power supply cable between Power Unit and IQ-Control Panel.
Lay control cables between Power Unit and IQ-Control Panel.
Option: lay a control cable between heat pump and IQ-Control Panel.
Option: lay a power supply cable from each output to the heat pump and to the heating cartridge.
Inform your electricity supply company in writing in good time before commissioning the XRGI system and say when you
expect to start using it. Ask the electricity supply company's network master to handle commissioning.
Be at hand personally when the system is commissioned, and send the correctly completed VDEW commissioning report
to the electricity supply company immediately after commissioning.
