External Power Supply - Siemens LDS 6 Operating Instructions Manual

External power supply

The three channel version of LDS 6 uses an external power supply for the optics housings. The
setup at the optics housing site is the same as for one and two channel systems. Also the ATEX
version of the three channel LDS 6 is using an external power supply leaving the optics housings
unaffected when a third channel is added. The external power supply is connected by adding the
pins into two corresponding screws of the 6 pole socket at the back of the central unit as seen
in the following figure.

The external power supply is intended for non-removal mains connection.
It is recommended to provide a switch in the mains connection so it is possible to switch it off.

The external power supply is no longer needed for 3 channel devices with the switch to the new
internal power supply starting from serial number: N1N8105258.
