Electromagnetic Compatibility And Susceptibility; Protection From Electric Shocks; Variations In The Nominal Of The Use - Chauvin Arnoux MH 60 Notice De Fonctionnement

6.3.2. Electromagnetic compatibility and susceptibility

Compliant with IEC 61326-1 for emissions and immunity in industrial use.

6.3.3. Protection from electric shocks

Type A clamp with double insulation or reinforced insulation in the grip part in
normal use, and double insulation or reinforced insulation between the primary
and the secondary output and the terminations part of the USB power supply and
the BNC output.
Maximum service voltage per EN61010-2-032
- 300V in installations of category III and degree of pollution 2.
- 600V in installations of category II and degree of pollution 2.
