ABB  Induction Motors and Generators Safety Instructions AMA, AMB, AMG, AMH, AMI

Intended use

Electric machines have dangerous live and rotating parts and may have hot surfaces. All operations serving transport, storage, installation, connection, commissioning, operation and maintenance shall be carried out by responsible skilled persons (in conformity with EN 50 110-1 / DIN VDE 0105 / IEC 60364). Improper handling may cause serious personal injury and damage to property. Danger! These machines are intended for industrial and commercial installations as components as defined in the Machinery Directive (MD) 98/37/EC. Commissioning is prohibited until conformity of the end product with this directive has been established (follow particular local safety and installation rules as, for example, EN 60204).

These machines comply with the harmonized series of standards EN 60034 / DIN VDE 0530. Their use in explosive atmosphere is prohibited unless they are expressly designed for such use (follow additional instructions). On no account, use degrees of protection ≤ IP23 outdoors. Air-cooled models are typically designed for ambient temperatures of -20°C up to +40°C and altitudes of ≤ 1000 m above sea level. Ambient temperature for air-/water-cooled models should be not less than +5°C (for sleeve-bearing machines, see manufacturer's documentation). By all means, take note of deviating information on the rating plate. Field conditions must conform to all rating plate markings.

Transport, storage

Immediately report damage established after delivery to transport company. Stop commissioning, if necessary. Lifting eyes are dimensioned for the weight of the machine, do not apply extra loads. Ensure the use of correct lifting eyes. If necessary, use suitable, adequately dimensioned means of transport (for example, rope guides). Remove shipping braces (for example, bearing locks, vibration dampers) before commissioning. Store them for further use. When storing machines, make sure of dry, dust and vibration free location (danger of bearing damage at rest). Measure insulation resistance before commissioning. At values of ≤ 1 kΩ per volt of rated voltage, dry winding. Follow the manufacturer's instructions.

Electrical connection

All operations must be carried out only by skilled persons on the machine at rest. Before starting work, the following safety rules must be strictly applied:

• De-energize! 

• Provide safeguard against reclosing! 

• Verify safe isolation from supply! 

• Connect to earth and short! 

• Cover or provide barriers against neighbouring live parts! 

• De-energize auxiliary circuits (for example, anti-condensation heating)!

Validity 

These instructions are valid for the following ABB Oy's electrical motor types, when the machine is used in explosive atmosphere.
