6.5 Connecting the valve electrically
1. Protect the electrical connections from direct contact with
rain water.
2. Lay the cables and pipework so that neither condensate
nor rain water can get into the plug unions.
3. Check that all plug cable glands and fittings are mechanic-
ally secured.
ð The cable must be held firmly on all sides.
4. Check whether the actuator cover/manual override is
closed and undamaged.
5. Correctly close the actuator cover/manual override again
immediately after use (see chapter "Manual override" (see
"Manual override", page 29)).
6. Correctly close the product again after replacing the dia-
phragm (see chapter "Diaphragm replacement").
