Connecting the device
9.4 Connecting external switch to turn device on and off
I
NOTE
Use cables with a cable cross section of 0.25 – 0.75 mm².
You can use the following as an external switch:
• external switch, voltage supply from the device: fig. b A
• Control unit with relay or transistor circuit (TR): fig. b B
• external switch with voltage supply from the battery (BAT) of the vehicle:
fig. b C
• external switch with its own voltage supply (DC POWER) e.g. from the ignition:
fig. b D
➤ Set the main switch (fig. 2 1, page 1) to "OFF".
➤ Make sure that the connection for the DSP-EM (fig. 2 10, page 1) is not
assigned.
➤ Set the main switch (fig. 2 1, page 1) to "REMO.".
➤ Connect the external on/off switch with the connection cable to the terminal
(fig. 2 11, page 1).
9.5 Connecting a relay
You can install a relay which monitors whether the 230 V input is connected.
Thereby you can, for example, implement an immobiliser so that the vehicle cannot
be started when the 230 V input is connected.
➤ Connect the relay as shown (fig. c):
– NO: normally open contact
– COM: common contact
– NC: normally closed contact
