The earthing system Ex-SYMEGA-VO serves to avoid electrostatic charges in hazardous areas and ensures a secure connection of stationary and mobile, metallic or conductive and dissipative objects and a good earth.

This ATEX earthing system visualizes the presence of a good earth via green LED and, if connected, can enable or interrupt the subsequent process via potential-free changeover contacts.

The earthing system Ex-SYMEGA-VO can operate in two different variations:

Variation 1: Low-resistance measurement of 0…1 kOhm or 103 Ohm.
Variation 2: High-resistance measurement of 0…3 MOhm or 3×106 Ohm.

Can be used in:
II (1) 2G Ex eb ia mb IIC T4 Gb
II (1) 2D Ex ia tb T120°C Db
Zones: 1, 2, 21, 22.
