Check that the current absorbed by the electric pump is compatible with the maximum current that can be supplied by the
device
•
Electrical connection must be performed according to the local regulations in force.
•
The electrical conductors must in particular be protected from high temperatures, vibrations and bumps that could cause
mechanical or chemical damage.
