DANGER
Incorrect connection to the mains
Danger of death from electric shock!
▷ Observe the technical specifications of the local energy supply companies.
▷ The core cross-section has to be at least 3 × 0.75 mm
▷ Use a slow acting circuit breaker of at least 1.4 × the nominal current of the
pump set. For the nominal current see name plate.
▷ The power cable has to be fitted with an all-pole isolating switch with a
minimum contact opening of 3 mm. A shockproof plug must not be used.
▷ If the power cable of the device is damaged, have it replaced by the
manufacturer, a customer service technician or a similarly qualified person. See
EN 60335-1.
NOTE
Using a permanently installed power cable of type H05VV-F 3G1.5 or similar is
recommended.
Using a universal AC/DC sensitive residual current device to DIN VDE 0160 is
recommended. Conventional residual current devices might either fail to trip or trip
erroneously.
Discharge current per pump < 3.5 mA
5.6.1 Connecting the power cable
1. Verify the supply voltage at the site against the data on the name plate.
2. Switch off the power supply and make sure it cannot be switched on again
unintentionally.
3. Fit the union nut and joint ring on the power cable.
4. Guide the power cable through the plug housing until the cable ends are freely
accessible.
5. Strip the power cable as shown in the illustration.
Strip about 18 mm of the earth conductor sheath. Strip about 13 mm of the
neutral conductor sheath and L conductor sheath.
Strip 6 mm of each core's sheath as a minimum.
