Before voltage is applied to the equipment the following checks must be performed:
 Check that screws are firmly seated in
 Connecting terminals, protective earth conductor terminals and
potential equalisation terminals
 Housing cover
 Check
 The torque of the cable lead-in
 The tightness of the seal provided by the cable lead-in
 Check whether the equipment is ready for operation
 The parameterisation for this application must have been performed
 All interfaces such as inputs and outputs for control purposes must be connected
and ready for operation
5.1 Parameterisation

Note:
Switching pressure specifications apply to vertical installation which is also the recommended position
with pressure-pipe connections pointing downwards. If the switches are installed horizontally with AMP
connection terminals uppermost, the switching values are approx. 20 Pa higher.
 Once the power supply is applied, the equipment is ready for operation immediately.
