4:2.1 Handling when mounting
The softstarter is available in five physical sizes. Models PST30 to PST300 can be taken out of the
packages and mounted without lifting equipment.
For all other models, lifting equipment is recommended due to the weight.
See Chapter 3 “Description”, for weights.

Warning!
Do not lift the softstarter by the connection bars. Lifting by the connection bars may cause
damage to the product.
