Use screened cables with a cross-sectional area
of minimum 0.5 mm
2
and maximum 1.5 mm
2
for
the external on/off switch, digital input, setpoint
and sensor signals.
•
Connect the screens of the cables to the frame at

7.7 Bus connection cable
7.7.1 New installations
For the bus connection, use a screened 3-core cable
with a cross-sectional area of minimum 0.5 mm
2
and
maximum 1.5 mm
2
.
If the motor is connected to a unit with a cable clamp
which is identical to the one on the motor, connect
the screen to this cable clamp.
If the unit has no cable clamp leave the screen
unconnected at this end. See fig.

8. Operating conditions
8.1 Maximum number of starts and stops
The number of starts and stops via the power supply
must not exceed four times per hour.
When switched on via the power supply, the pump
starts after approximately 5 seconds.
If a higher number of starts and stops is desired, use
the input for external start-stop when
starting/stopping the pump.
When started via an external on/off switch, the pump
starts immediately.
8.2 Ambient temperature
8.2.1 Ambient temperature during storage and
transportation
Minimum: -30 °C
Maximum: 60 °C.
8.2.2 Ambient temperature during operation
The motor can operate with the rated power output
(P2) at 40 °C, but continuous operation at higher
temperatures reduces the expected product life.
