ted, competent personnel.
d) Always observe the applicable safety regulations for the operating site.

4.1 Installation
Please note before installing the level switch!
After transport and delivery of the level switch, the switching status of the bistable contacts may be different than required for
proper operation.
Therefore slide the float for the level switch along the level switch tube from below immediately before installation.
This ensures all built-in bistable contacts have a clearly defined switching status (NC or NO).
The level switch comes fully assembled and can be mounted to the tank by screw-in thread or flange and mounting screws.
Please be sure the float can move freely and to leave enough space between the tank wall and add-ons.
After removing the float, where applicable, be sure the magnet inside the float is above the fluid level. This can easily be verified
with a piece of iron to determine the magnet position inside the float.
DANGER Electric voltage

When connecting devices, please note the maximum voltages and currents currents (see
technical data) and use the correct wire cross-sections and circuit breakers.
When selecting the connection lines, also note the maximum operating temperatures of
the devices.
Installation in special areas of application:
If the device will be installed outdoors or in wet areas, the maximum operating voltage
