Note
• The supply voltage must be switched off before the pressure
option is installed.
• The bonding wires for the pressure option must not be
touched. Doing so will cause damage to the option module.
• Before using the device, a high-voltage test in accordance
with IEC must be performed.
1. Loosen the screws for the housing cover and remove it.
2. Loosen all cable connections on the screw terminals.
3. If present, unscrew the option modules and remove them
from the side.
4. If present, remove the mechanical position indication and
screw off the shaft extension (as well as the mechanical alarm
signaling unit if applicable).
5. Remove the screws for the plastic cover and remove the
cover.
6. Remove both plug connectors from the printed circuit board.
7. Unscrew the fixing screws for the printed circuit board and
