1. General information 2. Description 1. General information The applicable national, local and plant-specific regulations and requirements must be observed. Technical details may vary for special designs and constructions. In case of doubt it is urgently recommended that the manufacturer is contacted, giving details of the type and serial number (No. …. see rating plate), or have the maintenance work carried out by a service centre. 2.
3. Notes 3.2 Installation For vertical configuration, all available lifting lugs and if necessary lifting straps (DIN EN 14921:2000) and/or tie-down straps (DIN EN 12195-2:2001) must be used to stabilise the position. Attachments must not be used as lifting aids. After installation, screwed-on lifting lugs must be tightened or removed. For vertical installation with the shaft end pointing downwards, a protective cover for the fan cover is recommended, to prevent the entry of foreign bodies.
3. Notes For tightening torques of screw connections of the electrical connections and terminal board connections (except for the terminal bar) see Fig. 4. 3.6 Checking the insulation resistance Prior to the initial commissioning of the motor after a long period of storage or standstill (approx. 6 months) the insulation resistance of the windings must be checked. During and immediately after the measurements, the terminals have voltages which can be dangerous, and must not be touched.
4. Maintenance Safety measures Before starting any work on the motor or the device, but especially before opening the covers of active components, the motor must be isolated according to regulations. In addition to the main power circuits, any additional or auxiliary circuits must be taken into account. The usual "5 Safety Rules" e.g.
4. Maintenance General overhaul A general overhaul of the motor must be carried out every 5 years. For this the motor must be dismantled.
5. Motors with increased ignition protection, type "e" Ex e 5. Motors with increased ignition protection, type "e" Ex e 1MA Identification: CE 0102 II G Ex e lI T3 Attention Repairs must be carried out in or by authorised workshops. Repairs must be documented on the motor (e.g. additional plate). The increased hazard in areas endangered by explosions or fire damp requires particularly careful observation of the general safety and start-up information.
5. Motors with increased ignition protection, type "e" Ex e In the case of external sources of heat or cold, no additional measures are necessary if the temperatures of the attached components do not exceed the permissible temperatures listed in Table 3. The values in Table 3 apply for an ambient temperature of -20°C to +40°C with self-ventilation.
