2.2 Mounting
The VBC-HV box can be mounted using the 4 mounting holes. To ensure
the best read out we recommend that you use the standard supplied
cables and place the controller as close as possible to the batteries.
During prolonged periods of high current, the shunt will become hot. It is
therefore recommended that the box is mounted so that the blades of the
shunt are oriented vertically to allow optimal air-flow.
2.3 Wiring
Turn off the power from the batteries and remove the fuse before you
start installation. Connect the wiring as shown in figure 1. The thick lines
represent the main current path cables; these should be of a heavy duty
type. Most of the connections are already made to the VBC-HV. You will
only need to connect the battery minus and system ground wires to the
shunt and the Battery+ wire to the battery. Optionally you can connect the
wires coming from the alarm relay.
Connect the Battery Controller to a VE.Net Panel or other VE.Net device
using a standard straight Cat5 cable. The total length of Cat5 cables used
in a VE.Net network should not exceed 100m.
After installation, and checking all the connections place the fuse to
power the battery controller.
Note: The VBC-HV cannot provide power to other VE.Net devices. In
order to power other VE.Net devices (such as the VPN), use either the
VE.Net power cable or connect another device to the network that is
capable of supplying power. Such devices include the VE.Net Battery
Controller 12/24/48V (VBC000300000), the VE.Net to VE Bus Converter
(VVC000200000), the VE.Net Tank Monitor, current model
(VCS000100000) and the VE.Net Tank Monitor, voltage model
(VVC000100000).
Note: The shunt and temperature sensor should be the only wires
connected to the negative terminal of the battery. The negative
connections of all other devices (including chargers) must be made to the
load side of the shunt (system ground). If devices are connected directly
to the negative terminal of the battery the VBC-HV will be unable to
measure their current consumption, and will give incorrect readings.
