Parallel operation of several devices
Up to three (others on request) of the devices described here can be operated in parallel. Parallel operation refers to the merging of
the power outputs (with the exception of the ground connection, see chapter 4.5.3) of several devices. This means the contacts 2,
4, 11 and 12 are to be connected individually for each device.
DANGER!
Risk of electric shock!
If several devices are connected via a bus, the connecting cables can be live, even if they are
unplugged on the device side. However, the interface makes it possible to detect when a device is
unplugged while other devices are still operating.
→
Do not rely on the connecting cables alone, as the device will not be de-energized and without voltage
even without connecting cables, as long as the primary side of the IP
®
system is active.
→
Turn off the primary side.
→
Check that the status LEDs of all devices are not lit.
→
Make sure that the manifolds are de-energized and without voltage.
When using the interface:
The isolated structure makes it possible to connect the interfaces in series. However, we recommend connecting each port
separately to pinpoint and locate exactly where a signal is coming from and to initiate the necessary responses. It may be possible
to selectively reset a single device in error mode without having to shut down the entire vehicle.
As mentioned above, it is possible to detect a disconnected/broken connection line. A closed “alert relay” and an open “status relay”
while the “on” signal is present is the characteristic feature of such an unsafe condition when other devices are still in operation.
