Danger!
danger of explosion caused by electrostatic charge.
In the event of a sudden discharge from electrostatically charged
devices or individuals there is a risk of an explosion in the Ex area.
▶ Implement suitable measures to ensure that there are no
electrostatically charges in the Ex area (see also "3.1. Use in Ex
area").
▶ Clean the device surface by gently wiping it with a damp or anti-
static cloth only.
▶ Earth the actuator and valve body.
▶ If a plastic body is used, earth the actuator separately.
