4.4. Electrical connection
4.4.1. Electric motor connection
Piston pump units with reservoir are driven by
electric motors.
The general conditions for connections are given in
 Table 8.
Danger!
Electrical connections for the piston pump
unit with reservoir may only be established
by qualified and trained personnel
authorized to do so by the operator, and in
observance of the local conditions for
connections and local regulations (e.g.,
DIN, VDE). Incorrectly connected piston
pump units with reservoir can cause
considerable damage to property and
result in serious injury or death.
Danger!
The mains voltage (supply voltage) must
match the specifications on the  rating
plate of the piston pump unit. Check the
fuse protection of the electrical circuit. Use
only fuses with the prescribed amperage,
else bodily injury and property damage
may result.
