For commissioning, the following reference documentation must be available::
• This data sheet.
• HVAC job diagram.
Check to ensure that all permissible values as contained in the section "Technical
data" have been observed.
• Check for proper mounting and ensure that all mechanical settings correspond
to the plant-specific requirements. Additionally, ensure that the dampers are
tightly closed when in the closed position.
• Check the direction of rotation.
• Fasten the actuator securely to avoid twisting and blocking of the actuator.
• Check to ensure that the cables are connected in accordance with the plant
wiring diagram (see "Wiring diagrams").
• The operating voltage AC/DC 24 V (SELV/PELV) or AC 230 V must be within
the tolerance values.
