Electrical connection and commissioning

Before you begin with the installation and commissioning of the
following notes:
• Make sure that the system is disconnected from the power supply.
• Make sure that no one is in the danger zone.
• Check the danger zone and take measures to prevent persons from entering (e.g. erect warning
signs, set up cordons or similar).
NOTE
Laying cables!
 Lay all connection cables and signal lines within the electrical installation space or permanently in
cable ducts.
 Lay the cables and lines so that they are protected against external damages.
 For further information: see EN ISO 13849-2, Table D.4.
