Degree of pollution 2 IEC 62103, EN 62477-1, not conductive
LABS compatibility The unit does not release any silicone or other LABS-critical substances and is suitable for
use in paint shops.
*) Operational temperature is the same as the ambient or surrounding temperature and is defined as the air temperature 2cm below the
unit.
**) Do not energize while condensation is present
19. PROTECTION FEATURES
Electrical protection Electronically protected against overload, no-load and short-circuits
Over-voltage protection in
buffer mode
Typ. 58Vdc
Max. 60Vdc
In case of an internal buffer module defect, a
redundant circuit limits the maximum output voltage.
Buffering stops and automatically attempts to restart.
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 3.5mm E.g. screws, small parts
Reverse polarity protection Yes Max. -60V
Input overvoltage protection No
Internal input fuse Not included
20. SAFETY FEATURES
Class of protection No classification
according to IEC 61140 or
IEC 60950-1 possible
Install the buffer module according to Class III rules
Isolation resistance > 500MOhm
> 500MOhm
> 500MOhm
Supply voltage to signal port
