Initial inspection
After unpacking your soft starter panel, inspect
it for damage that may have occurred during
shipment.
If any damage is found, please report it to the
distributor from which the panel was purchased.
Care should be taken when unpacking the panel;
improper use of tools could damage equipment.
Preparing for installation
Remove and discard desiccant/drying/silica
packs if included.
Before you begin to install the PSTX soft starter
panel, make sure the proper equipment for lifting
is available. Refer to the appropriate outline
drawing for the dimensions, estimated weight
and required clearances for installation. Refer to
the rating label on back of the cover to verify that
the received product matches the ordered unit
and verify the product listing/marking label.
Improper lifting of enclosure could result

should be taken when unpacking the panel;
improper use of tools could damage equipment.
Enclosure panel doors can swing more than
90 degrees, and there are no stops to inhibit
the door from hitting equipment located next
