12 VDC Cable
The 12 VDC power supply is supplied with a 3 metre red/black cable of two pairs of 2.3 mm
2
(72 strands of
0.2 mm
2
) making a total of 4.6 mm
2
per connection. This increase in wire size is to carry the increased
current consumption of the 12 VDC supply (max 18 Amps per terminal).
This 3 metre cable is engineered to power a fully loaded terminal from a 12 VDC supply. A longer cable
should not be used as the additional voltage drop could cause the power supply to fail.
If longer cable runs are required between the 12 VDC power supply and the terminal, it is suggested that
high current distribution bus bars are used to feed the rack and the supplied power cable used between
the bus bars and the terminals.
