Ecosmart Speed Control
Installation and Maintenance
Always handle with care to avoid damage and distortion, and where
lifting slings are employed use spreaders to ensure slings do not come
into contact with the unit case, or control pack (see fig. 2).
2.2 Dimensions (mm) & Weights (Kg)
Control sizes are selected by matching the unit full load current with
the control code i.e. control code ES-ISC3.3A is suitable for a fan with a
maximum full load current of 3.3A.
The Inverter overload is pre-set at the rating plate value, if a lower
setting is required fit an appropriately sized overload relay to the output
contactor and adjust accordingly.
