5. Notes on the operation
During installation, ensure good ventilation and sufficient space for heat dissipation; keep away from flammable, explosive materials and precision equipment.
Before commissioning, check the insulation resistance, wiring, temperature controller and communication module.
Check the temperature controller, winding cleanliness and grounding regularly to avoid dust and oil accumulation.
Before restarting after a long period of inactivity, check the thermal insulation; additional drying is not required.
Operate at rated load; avoid prolonged overload; follow temperature controller instructions for short-term overload.
