WARNING

Device is live!

Incorrect connection may result in injury or death!

‣

The electrical connection may be performed only by an electrical technician.

‣

The electrical technician must have read and understood these Operating Instructions

and must follow the instructions contained therein.

‣

Prior

to commencing connection work, ensure that no voltage is present on any cable.

6.1

Connecting the spectrometer

The following connection options are available:

• Via M12 plug (version: fixed cable, M12 plug)

• Via the cable of the spectrometer to the plug-in terminals of an input of the transmitter

(version: fixed cable, end sleeves)
