With reducers to 100 mm The regulations of IEC 60079-10apply. The motor must be pro-
tectedby a circuit breaker whichisolates the equipment in case
of a short circuit within the time
shown on the explosion proofcertificate. The inlet and exhaustmust be protected by guards or
other devices to prevent items
entering the fan which are big-
ger than 12 mm. Approved foroperation mode. VDE 0530 =S1 (continuous operation).
