Enclosure, Wiring; Ossd Test Pulses - Kollmorgen AKD series Installation Manual

7.16.6 Enclosure, wiring

Since the drive meets IP20, you must select an enclosure that permits safe operation of the
drive. The enclosure must at least meet IP54 .Wiring remaining within the specified enclos-
ure must meet the requirements of the standard IEC 60204-1 and ISO 13849-2 (Table D.4).
If you are wiring leads that are outside the specified enclosure (IP54), the cables must be laid
durably (firmly), protected from outside damage (for example, by laying the cable in a duct),
placed in different sheathed cables, or protected individually by grounding connection.

7.16.7 OSSD test pulses

Safety controllers usually check their outputs periodically during the normal operation. These
test procedures create pulses to the STO-Enable input.
Test pulses with T1 ≤ 300 µs and T2 ≥ 200 ms will not have any influence to the safety rel-
evant STO function.
Test pulses, which are outside of this specification, will switch the STO function, but will not
create a dangerous situation.
