Installazione & Linee guida per la manutenzione
Specifiche di installazione

Flange mounting surface must be flat and clean; bolt torque follows SEW standards (18 Nm per bulloni M8)

Use flexible coupling for output shaft connection to avoid excessive radial force

Ensure good heat dissipation at installation location, keep at least 100 mm away from heat sources

Requisiti di cablaggio

Motor must be grounded for safety

Secure terminal connections inside terminal box; crimped lugs recommended

Stepless speed control via frequency inverter is compatible with DRS series motors

Intervalli di manutenzione

Ispezione di routine: Once per month, check noise, vibrazione, temperatura

Annual maintenance: Clean motor fan cover, check terminal tightness

Cambio: Lifetime maintenance-free, no grease replacement required
