8.1 Electrical connection
+
All maintenance and installation work must be carried out with the equipment fully isolated from the power supply!
The electrical connection is to be carried out by a certified electrician in accordance with wiring diagrams SS-991.1,
SS-992.1 and SS-993.1!
The relevant standards, safety regulations (e.g. DIN VDE 0100) and the technical connection regulations of the energy supply companies
must be observed. An all-pole mains switch/isolator, with at least a 3 mm contact opening (VDE 0700 T1 7.12.2 / EN 60335-1) is manda-
tory! The rated voltage and frequency must be consistent with the information on the type plate.
8.2 Initial commissioning
The following points must be checked prior to initial commissioning:
– Check the intended purpose of the fan!
– The series must not be operated in potentially explosive atmospheres!
– Installation and electrical installation completed professionally
– Check fan for solid mounting
– Check all parts for tightness, particularly screws, protection guards
– Are the safety devices professionally installed
– Accessories professionally installed
– Protection against accidental contact
– Remove assembly residues or foreign bodies from the fan area
– Check free movement of the impeller! Fan impeller must not grind against stationary housing parts
Commissioning may only take place if protection against accidental contact with the impeller is ensured
– Check sealing of connection cable and firm clamp position of wires
– Cable entry sealed
