Example of a switching cupboard with ventilation
Notes:
• Distance between casings: short form 2A, 4A, 5A, 8A >40mm
(casing to casing) long form 2A, 5A, 8A >30mm
short form 16A, 25A >10mm
• If a DPS-1 option module (PROFIBUS-DP) is used, the minimum distance of the long form may
have to be increased due to the PROFIBUS plugs.
• For fixing use cylindrical screws M6 (Inbus screws) and for mounting a hexagonal screwdriver size
5.
• If there are more than three PMC-2s in one switching cupboard, a fan is needed to provide
sufficient air flow.
