Product overview
2. The earth terminal at the left end plate of the electrical linkage of the product and the earth ter-
minal at the power supply connection must have the same potential. There must be no equalising
currents.
3. If necessary, replace the electrical connection pre-installed on the energy efficiency module with a
longer, electrically equivalent connection.
