Instalare & Ghid de întreținere
Specificații de instalare

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

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

Cerințe de cablare

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

Intervalele de întreținere

Inspecție de rutină: Once per month, check noise, vibratie, temperatură

Annual maintenance: Clean motor fan cover, check terminal tightness

Gearbox: Lifetime maintenance-free, no grease replacement required
