WARNING
Simultaneous connection of several motors to the PumpDrive output
Damage to PumpDrive!
Fire hazard!
▷
Never simultaneously connect several motors to the PumpDrive output.
CAUTION
Improper dielectric test
Damage to PumpDrive!
▷
Never carry out dielectric tests on PumpDrive components.
▷
Only carry out dielectric tests on the motor, motor connection cable, or power
cable after having disconnected the PumpDrive connections.
NOTE
Depending on the combination of settings, PumpDrive could conceivably restart
automatically after acknowledgement/reset or when the cause of the malfunction
or fault has been eliminated.
PumpDrive is equipped with electronic safety devices, which in case of a fault or
malfunction trip and de-energise the motor, causing it to stop.
Use only the available cable gland holes (if necessary, in combination with double
cable glands) for establishing the cable connections. Any additional drilling could
generate metal chips and damage the equipment.

Information for planning the system
5.4.2.1
Connection cables
Selecting the power/connection cables
The type of cable you choose depends on various factors such as, for example, the
type of connection, the ambient conditions and the type of system.
Power/connection cables must be used in accordance with their intended use, and
the manufacturer specifications regarding nominal voltage, current, operating
temperature and thermal effects must be observed.
Power/connection cables must not be routed across or near hot surfaces (unless they
have been designed for this kind of application).
When they are used in mobile system components, flexible or highly flexible power/
connection cables must be employed.
The cables used for connections to permanently installed devices should be as short
as possible and be properly connected to these devices.
Different earth bus bars should be used for control and power/motor connection
cables.
Unshielded cables can be used as power cables.
The power cables must be designed with a cross-section suitable for the nominal
mains current.
If a contactor is used in the power cable (upstream of PumpDrive), this must be
configured for an AC1 duty rating; the rated current values of the PumpDrives used
are added and the result is increased by 15 percent.
Shielded cables must be used as motor connection cables.
Shielded cables must be used as control cables.
