2 - 2 VC80 User Guide
Installing the VC80
Electrical Installation
There are various electrical potentials when installing the unit on a vehicle such as a forklift.
Figure 2-1 VC80 Ground Lug
Most electrically driven forklift vehicles have floating chassis connected to
neither DC+ or DC-. However, electrical faults can cause the battery + or - to be
connected to the chassis via low resistance paths. All connected peripherals
must be completely isolated.
The VC80 accepts DC power sources with a minimum of 10VDC nominal and
48VDC nominal. A Power Pre-regulator is required for voltages above 48VDC
nominal.
Applying a voltage above 48VDC nominal without the pre-regulator or reversing
polarity may result in permanent damage to the VC80 and voids the product
warranty.
CAUTION
Attach the VC80 connecting cable as close to the battery as possible. Connecting the VC80
to large electrical loads, such as converters for the forklift motor may result in random
restarts, malfunctions and/or irreparable damage to the device.
To connect devices fed by other power sources to the VC80, such as printers, power up the
peripheral devices at the same time or after the VC80 to avoid start-up problems,
malfunctions or irreparable damage to the device.
