In order to prevent damage or serious injury when
commissioning the switchgear, the following
points must always be observed:
• The switchgear must be installed as described in
the “Installation” section and in accordance with
the applicable national regulations.
• The switchgear must be properly fused and
grounded.
• All unit safety devices and emergency cut-outs
must be connected and inspected to ensure that
they are working properly.
• The switchgear is suitable for use under the spec-
iedoperatingconditions.

injuries from explosions! The switchgear and
connected pump and signal transmitter must
always be used outside of potentially explo-
sive areas.
7.3. Activating the switchgear
POTENTIALLY fatal danger due to electrical
voltage
All settings need to be made on the switch-
gear components. When performing work on
the uncovered switchgear, there is a risk of
fatal electric shocks occurring. All work must
be carried out by a qualied electrician.

During factory setting, the switchgear is checked
for clockwise direction of rotation and adjusted to
ensure the direction of rotation is correct.
