Note!
Non-electric actuators and control valve versions do not have their own potential ignition
source according to the ignition risk assessment stipulated in EN 13463-1: 2001, section
5.2, even in the rare incident of an operating fault. Therefore, they do not fall within the
scope of Directive 94/9/EC.
For connection to the equipotential bonding system, observe the requirements specified in
EN 60079-14: 1977 (VDE 0165 Part 1), section 6.3.
