To monitor other loads in the load balancing network
1.
When other loads in the premises need to be monitored by the load monitor, the current transformer
cables must be installed from the energy meter in the CGC500™ to the relevant metering point.
2.
Install one current transformer per phase, i.e. three current transformers: L1, L2 and L3. Below is an
example of connection in a 3-phase system.
Note:
Current is measured via the current transformers. Make sure that the current transformer is installed
in the correct direction, so the value is not inverted. The current and voltage must be measured on the same
phase. A neutral conductor must be available.
To check before installation
1.
Plan the installation regarding all subsystems; charging stations, the CGC500™, Ethernet switch, cur-
rent transformers and cables.
2.
Make sure that the placement off all equipment is suitable for normal operations and maintenance.
3.
Make sure that the wall is suitable for mounting the enclosure of the CGC500™. CGC500™ should be
installed close to the measurement point (incoming feeder cables or next to the main fuse). Also make
sure that the wall can support the weight of the enclosure with components. The weight is approx. 9
kg.
4.
If Internet access is via 3G/4G, make sure that there is adequate coverage at the relevant location
for the equipment. Do not install an antenna inside the CGC500™ enclosure as this may block the
reception.
To install the EV charging station
1.
Connect the Ethernet and power cables to the EV Charging stations. All Ethernet cables must be con-
nected to the same local area network, LAN.
2.
Connect the power phases to the EV charging stations. Note the phase rotation. This must be known
when the load balance is configured in the software configuration.
To configure the EV charging station
Configure each individual EV charging station from the built in Web GUI accessed via the mini USB interface
to activate NanoGrid™. Refer to “CCU NanoGrid Configuration Manual, Pd_CM_004”.
Verify that the each EV charging station’s firmware version is R3.6.1 or higher. Remember to reboot after
changing the configuration.
To install the CGC500™
1.
Locate the mounting holes and mount the enclosure with suitable screws for the wall.
2.
Insert the incoming cables (electrical, Ethernet and transformer cables) into the enclosure at the top
or at the bottom. Separate communication cables and power cables from each other.
