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

Требования к проводке

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, вибрация, температура
