The BPS is designed in accordance with protection class III for supply with PELV (protective
extra-low voltage).
NOTICE
Connection hood and degree of protection IP 65
Ä
Before connecting, mount the connection hood on the BPS device housing.
Ä
To ensure degree of protection IP 65 is fulfilled, the screws of the connection hood are tight-
ened with a tightening torque of 1.4 Nm for connecting to the BPS.

External parameter memory in the connection hood
To enable simple exchange of the BPS, the integrated parameter memory of the MS 307 and MK 307 con-
nection hoods store a copy of the current parameter set.
Also located in the MS 307 and MK 307 are switches S1 and S2.
• Slide switch S1 is used to toggle the encoding of the output measurement value between
Gray
and
bi-
nary
.
• Rotary switch S2 is used to set the resolution of the position value (in mm) or a speed monitoring func-
tion.
NOTICE
No parameter memory and no configuration switches in connection hood KB 307!
Ä
No parameter memory is integrated in connection hood KB 307.
