If pollution degree 2 cannot be guaranteed, IP54 protection class must be used.
The connections of the Safety signals are made at connector X7, located at the bottom
of the servodrive, according to
Figure 3.1 on page 15 and Figure 3.2 on page 16 .
Additionally, the type of safety signals coming from the installation must be chosen at
a Dip Switch. See location at
Figure 3.1 on page 15 . The Dip Switch must be set
before energization, according to the description below:
„
"D" for Dry Contact devices, i.e., all devices that have electromechanical output
contacts, like relays.
„
"O" for OSSD (Output Signal Switching Device), i.e., devices that have outputs
containing test pulses.
NOTE!
The 24 Vdc power supply must attend Low Voltage Directive (2006/95/
EC), applying the specifications of IEC 61131-2:2007, Programmable
controllers - Part 2: Equipment requirements and tests and must attend
