Connection of Interface: X3
(view: contact side)
PIN 1
> Isolated 24 VDC
PIN 2
> Isolated 0VDC
(150mA maximum. Do not distribute externally: see chapter 8.1 and 8.2).
this internal 24V/150mA is different from the 24V/5A output available on X2
PIN 3
> COM
(common to the 3 output relays “Warning”, ”Error” and “Status”)
PIN 4
> Enable
(must be connected to allow the Regulator to power up. See chapter 8.1 and 8.2.)
PIN 5
> Warning
PIN 6
> Error
PIN 7
> Status
(relays have potential free contacts, rated for 30 V DC / 5 A max.)
PIN 8
> Ground
All pins are isolated from the main power output.
4.5.4
Ground Connection
All electrical equipment must be connected together to the vehicle frame to ensure an equipotential bonding. The ground output of
each plug must therefore be connected. In the same way, make sure to connect the housing of the device to the vehicle frame
(GND) and not rely only on the connection to ground provided by the power connector. The reason is that if the connection to the
load is removed while the IPT
®
primary is active, then the device is still internally energized though the ground connection is
broken.
4.5.5
ESD Protection
Because the IPT
®
system is isolated, some electrical charges may accumulate on the vehicle depending on the surrounding
conditions and the vehicle design. An adequate solution must be foreseen using a conductive floor coating together with for
example conductive brushes, sliders, track rollers, wheels or similar methods for a connection to Earth, in order to reduce the
likelihood of static charge build up and therefore ensure protection against electrostatic discharge (ESD).
