Tools
Screwdriver for slotted screws, size 2.5, completely insulated according to
DIN VDE 0680-1.
Screwdriver for cross-recess head screws, size 2
Note
Connect screens only to the specified terminals.
The loop resistance must be below 10.
The rated voltage is indicated on the name plate.
When switching off inductive loads, voltage spikes are produced that may
impair the operation of control and measuring systems. Connected
contactors must therefore be provided with suppressors such as
RC-combinations.
Even in correctly wired systems high frequency interference caused by the
installation can occur, leading to system outages and malfunction alarms.
For more information on malfunctions see “Fault finding list for
troubleshooting system faults“ on page 32.
