1.1 Power
Power the Color Control GX (CCGX) on the Power IN V+ connector. It accepts 8 to 70 V DC. The CCGX will not power itself from the network connections. Use a 1A slow blow fuse.
If you power the CCGX from an AC adaptor connected to the AC-out of VE.Bus products (Inverter, Multi or Quattro), then a deadlock will happen after the VE.Bus products are powered down for any reason (after any
operational fault or during a black start). The VE.Bus devices will inhibit their boot process until the CCGX is powered up, but the CCGX will not boot until it has power. This deadlock can be verified by briefly unplugging
the CCGX VE.Bus cable and observing that the VE.Bus products immediately start to boot.
This deadlock can be avoided in two ways:
Power the CCGX via the DC bus; or
Cut pin 7 in the VE.Bus cable connected to the CCGX
Cutting pin 7 of the VE.Bus cable to the CCGX (brown/white according to standard RJ45 ethernet cable colour coding) allows the VE.Bus products to start up without waiting for the CCGX to boot up first. It is harmless to
do this in any case (even if the CCGX is DC powered).
VE.Bus BMS note: when the CCGX is used in an installation with a VE.Bus BMS, connect Power in V+ on the CCGX to the terminal called 'Load disconnect' on the VE.Bus BMS. And connect both negatives to a common
Battery -.
Because the CCGX is connected to many different products, ensure that proper care is taken with isolation to prevent ground loops. In 99% of installations this will not be a problem.
The VE.Bus ports are isolated
The VE.Direct ports are isolated
The VE.Can ports are isolated
The USB ports are not isolated. Connecting a Wi-Fi Dongle or GPS Dongle does not create a problem, since it is not connected to another power supply. Even though there will be ground loop when you mount a
separately powered USB hub, we did extensive testing and it did not cause any issues
The Ethernet port is isolated, except for the shield: use unshielded UTP cables for the Ethernet network
Extending the number of USB ports by using a hub: there is a limit to the amount of power that the onboard USB port can provide. Especially when extending the number of ports, we recommend to always use powered
USB hubs. And to minimize the chance of issues, do not use the lowest cost USB hub available.
