4.5.1 General conditions for electrical connections
1) Protective measures that must be applied for designated usage:
"Functional Extra Low Voltage", "Protective Extra Low Voltage" (PELV)
Standards: EN 60204 Part 1: IEC 60204-1: DIN VDE 0100 Part 410 / IEC 364-4-41: HD384.4.41
2) Typical value at ambient temperature = 25 °C and operating pressure = 150 bar
3) Fuse in accordance with DIN 72581 T.3
4) Conductor: cross-section 1.5 mm

, length ≤ 12 m
5) No specification
The pump units in the KFG series are available
in voltage designs 12 VDC and 24 VDC.
The electrical voltage connection is established
through a 4-pin cable socket according to
DIN EN 175301-803 or a 7-pin circular
connector according to DIN 72585.
