Protective Housing

Use and testing 
Device category and suitability II

The protective housing as a piece of equipment is divided 

into Equipment Category II, i.e. for all explosion hazard 

areas except for potentially explosive areas with the 

exception of mine workings susceptible to firedamp. It may 

be used in accordance with the following description in 

areas subject to dust explosions.

Dust explosion protection II 3D, 

Equipment Protection Level (EPL) Dc

The Equipment Category II 3D with EPL Dc includes 

equipment with "increased" protection level for use 

in flammable dust atmospheres where there is no ignition 

hazard during normal operation and which has additional 

protection measures which ensure that there is no 

danger of ignition when expected fault conditions occur.

Protection by enclosures tc

A rating of tc means that no combustible dust can enter.

Dust Group IIIC

Dust Group IIIC includes possible use with conductive 

dusts, non-conductive dust and combustible lint.

Temperature Class T90°C

The temperature specification T90°C indicates that the 

surface temperature of the uncooled housing during 

normal operation lies within the permissible specification 

under all conditions at maximum 90 °C.

Notes for installation, operation and repair 

– Only sensors from the BOS 23K-…/BOD 23K-… and 

BOS 50K-…/BOD 50K-… series may be installed in 

the housing.

– Refer to Section 4 for installation.

– The protective housing may be installed on the 

machine in any orientation.

– The connection cable must be suitable for the 

application area and routing must be according to the 

requirements (fixed installation, protected against 

damage, etc.).

– The O-Ring Ø73 X Ø3 FKM75 (BAM PC-OS-024-23K-1) 

and Ø93 X Ø3 FKM75 (BAM PC-OS-024-50K-1) must 

be correctly installed and dust sealing of the housing 

ensured.

– The protective housing is attached to the machine 

using four M5 screws.

– The cover screw may be opened only for startup when 

there is no dust atmosphere present.

– During operation the cover screw must be closed so 

that it remains dust-tight.

– Dust buildup must be regularly removed.

– In explosion hazard areas the protective housing may 

be used only at a permissible ambient temperature of 

–5…+70 °C.

– In accordance with the conditions of use the protective 

housing must be regularly inspected for damage.

– If a malfunction occurs or damage becomes evident, 

immediately take the system out of service for repair.

– Damaged parts must be replaced only by original 

replacement parts. 

– The plugs may be plugged in or disconnect only when 

de-energized.

The following warning label is enclosed and must be 

attached in a clearly visible manner:

– The device has to be protected against impacts with 

high impact energy.
