Safety instructions for ABB induction motors and generators covering transport, installation, operation, maintenance and explosive‑atmosphere requirements.
This manual provides safety regulations and detailed procedures for handling ABB induction motors and generators. It covers general safety, intended use, transport, storage, installation, electrical connection, operation, maintenance, and special instructions for use in explosive atmospheres.
The document includes specific guidance for various ABB motor series (AMA, AMB, AMG, AMH, AMI, AMK, AMZ, HXR, M3BM, M3GM), covering topics such as pre‑start ventilation, earthing, clearances, and required protective equipment.
| Ambient temperature range (air‑cooled) | -20 °C to +40 °C |
|---|---|
| Maximum altitude | ≤ 1000 m above sea level |
| Maximum vibration severity (Vrms) | ≤ 4.5 mm/s |
| Clearance between rotor and stator after maintenance | ≥ 1 % of maximum diameter |
Air‑cooled models are designed for ambient temperatures from –20 °C up to +40 °C.
The shaft must be prevented from rotating and the machine must be de‑energized before opening the terminal box.
The maximum number of sequential starts is declared in the machine’s technical documents.
A clearance of at least 1 % of the maximum fan diameter must be maintained.
