4.1 Mounting the device circuit breaker
Mounting location The CBMC E4 ... IOL meets the IP20 degree of protection. The compact design means that
the device circuit breaker can be installed in standard terminal boxes.
Mounting/DIN rail The device circuit breaker can be mounted tool-free on the DIN rail.
Removal A standard tool (e.g., a bladed screwdriver with a blade width of 2.5 mm) can be used to re-
move the device circuit breaker.
Mounting position Mount the device horizontally. The ventilation slots should be oriented upward or down-
ward. Maintain a minimum distance of 30 mm on the top and bottom to ensure convection
cooling (see Figure 4-1 "Convection cooling"and Figure 4-2 "Minimum distance").
