CTEK GRID CENTRAL - CGC500™
The CTEK GRID CENTRAL 500 - CGC500™ is the high capacity version of CTEK’s grid central for
NanoGrid™ load balancing and monitoring of electrical vehicle charging networks. The CGC500™
can monitor and manage up to 500 charging station EV connectors. It can monitor other loads at the
installation site for load balancing of the entire power network. CGC500™ comes in three different
versions depending on the chosen current sensor:
• CGC500™ for 100 A and a maximum conductor diameter of 15.7 mm (Part no. 40-382)
Supplied with split core current transformers with cable length of 1.8 m.
• CGC500™ for 400 A and a maximum conductor diameter of 36 mm (Part no. 40-383)
Supplied with split core current transformers with cable length of 1.5 m.
• CGC500™ for 4000 A and a maximum conductor diameter of 179 mm (Part no. 40-384).
Supplied with Rogowski coils with cable length of 2 m.
The CGC500™ communicates with the charging stations using a LAN connection.

Installation
Safety
• Only an accredited electrician is allowed to perform the installation described in this document.
• Read and obey the instructions in this document before installation and operation of the product.
• Installation must fulfil local safety regulations and ensure the IP classification if the box is modified.
• Make sure that the cables in the CGC500™ are not loose due to vibrations during transport. If any
cables are loose, reconnect the wires and tighten the screws.
• Use safety shoes during installation.
Tools
Recommended tools for installation:
• Screwdriver
• Stripping pliers
• Spirit level
• Drill
• Ethernet cable
Other necessary equipment
The following parts are also needed to install the entire grid controlling network. These are purchased sep-
arately.
• CHARGESTORM CONNECTED® (or other CTEK charging stations compatible with the CGC500™)
• Ethernet switch
• Ethernet cables
• Screw joints for cable feeds
• Screws for wall mounting
General information before installation
To install the network cables
CGC500™ and every charging station must be connected to the same switch using Ethernet cables. For
instance, if there are eight charging stations in the installation, nine Ethernet cables will be required. If Inter-
net access is required, the switch must be connected to the appropriate access point.
Note:
The Ethernet cables must not be longer than approx. 90 m. If longer cables are needed, repeaters
must be used to strengthen the signal. The Ethernet cables must be Cat5 or Cat6 cables with an RJ45
connector at each end.
