7�3 Painting the control block/control block segment
For painting of the control block/control block segment before assembly, proceed
as follows:
▶ Apply protective plastic plugs at the hydraulic ports for protection against
ingress of paints.
▶ Screws have to be inserted into the fastening threads to prevent ingress of
paint.
▶ Protect flange surfaces of control blocks/control block segments against paint.
▶ Prevent any paint being applied to the contacts of the electrical connections
and make sure that the connectors are not damaged.
▶ Prevent fluids from entering the connector of the actuating unit. The connector
only meets the type of protection in the plugged and locked state.

no paint chips enter the control block/control block segment.
▶ Protect name plates against application of paint using a film that can be peeled
off after painting.
