DANGER
Risk of explosion if the switchgear is installed in potentially explosive
areas!
The switchgear does not have its own explosion protection class and must always be
installed outside of potentially explosive areas! The connection must be made by a
qualified electrician.
DANGER
Risk of explosion due to incorrect connection!
If pumps and signal transmitters are connected in explosive atmospheres, there is a
risk of explosion due to incorrect connection. Observe the section on explosive at-
mospheres in the appendix!
NOTICE
Error message during operation at the alternating current connection
The switchgear has a rotating field monitor and motor current monitor. Both monit-
oring functions only work trouble-free at the three-phase current connection and
are activated at the factory. If the switchgear is used at an alternating current con-
nection, the following error messages are shown in the display:
• Rotating field monitoring: Error code "E006"
