2.5 DC-contact (DC grid connection)
NOTERA! If the system will not have a DC grid, you can skip this
section (e.g. if the system is only to be used for phase balancing
and measurement/data collection).
NOTERA! The dc grid cable does not need to have an M-conductor
if it is not to be a Powershare installation (An interconnected DC
voltage network between EnergyHubs).
1. Bring out the installation kit for the DC connector. The
installation kit includes:
1. 1 x 4-pin hand contact
2. 1 x two-piece contact housing
3. 1 x strain relief rail
4. 2 x Phillips Screw (11mm) for Rail
5. 2 x flatscrew (18mm)
2. Contacts the DC connector as shown in the figure below.
Use end sleeves.
NOTE! The M conductor is contacted only when you connect
several EnergyHubs with each other.
1. Make sure that all conductors are screwed on.
2. Make sure that the strain relief is around the outer cable
as shown in the figure on the right marked with 2.
3. Make sure the EnergyHub is turned off before plugging in
the DC connector.
4. Screw in the fixing screws located on the DC connector
so that the DC connector cannot be detached without
tools.
Warning, the Ehub has capacitors on the DC side that can
hold charge even after the device is disconnected from
the AC side. Wait at least 5 minutes after turning off the
device before handling the DC connector

Make sure that the DC voltage network is plugged
in at the correct positions in the connector.
•
If it is a Powershare system, it is recommended to
put an external switch on the DC power grid.
