MSR127 Minotaur Monitoring Safety Relays Installation Instructions
Approximate Dimensions
Figure 3 - Dimensions [mm (in.)]
Installation
1.
Mount in enclosure (minimum rating of IP54).
2.
To remove terminals (P versions only), insert a
screwdriver and slowly move as shown.
Safety Specification
All MSR127 safety relays can be used in safety circuits according to EN ISO 13849-1
and IEC 61508/IEC 62061.
Specifications are applicable only if the safety function is demanded at least once
within 6 months. All diagnostic tests are conducted at least before next demand.
The mission time (TM) for the proof test interval (PTI) is adopted.
Components failure rates according to SN29500.
