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

Wiring Requirements

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

Maintenance Intervals

Routine inspection: Once per month, check noise, vibration, temperature

Annual maintenance: Clean motor fan cover, check terminal tightness

Gearbox: Lifetime maintenance-free, no grease replacement required
