Earth and short-circuit them andcover over any neighbouring electrically conducting components or block themoff. Failure to do so may lead to serious injury or death.NOTEThe cable installation must be carried out in accordance with the enclosedwiring diagram of the unit and nationally applicable standards and guidelines.Only one separate mains power cable should be used. Never connect otherunits to this mains power cable.7.1 RequirementsVisual inspection ofmechanical parts• Carry out a full visual inspection of the entire unit and installed components.• Before you start with the electrical connection, check the following:– The characteristics of the mains power supply must satisfyEN 60204-1 regulations and the power requirements of the unit.– The size of the backup fuse size must be determined on the basis of the unitrated current with consideration to the maximum fuse size (see wiring diagram)by the competent electrical tradesman.– The motors must be able to operate at their nominal capacity if their input voltagewith nominal frequency is between 95 % and 105 % of nominal voltage.7.1.1 Cable routing and grommets by others• The installation of cable grommets and the running of cables near doors, panelswith sash fasteners, panel connections and cover strips is to be be avoided.• Screw connections and grommets must not cause any leaks.• The connecting cables within the fan components must be long enough to allow themotor to be moved without difficulty (in order to tension the V-belt, for example).38 PR-2006-0019-GB • Subject to modifications • Status 05/2009
