Instruction Manual LDX2
Apparatus
The isolation/supply unit LDX2 is an auxiliary electrical appa-
ratus to which only approved intrinsically safe Höntzsch VA and
FA sensors may be connected. The safety-related peak values of
these sensors must comply with the technical data for the LDX2.
1. Safety precautions
Please read this Instruction Manual carefully before initial operation!
Non-compliance can cause an explosion!
Operation of the LDX2 is permissible outside the explosive atmosphere only and at an ambient tempera-
ture of max. +60 °C. The permissible supply voltage can be found on the type plate.
