1.2.2 Alarm Module with Voltages >50V (Option AM2) The optional alarm module is isolated from the low-voltage side of the EE33 by a special partition; this must remain fitted at all times in the back section of the enclosure.
The device may only be powered as decried in this manual. The use of the EE33 in any other way than described in this manual bears a safety risk for people and the entire measurement installation and is therefore not allowed.
