Important information concerning functional reliability
during continuous operation!
If switched off for a long period, at least 1-2 activations
per day are recommended.
Service life
High switching frequency and high pressures reduce the
service life.
6.3. conformity
CE mark conforms to EMC Directive 2004/108/EEC only if
