Length of motor connection cable
If PumpDrive is not mounted on the motor to be controlled, longer motor connection
cables may be required. The stray capacitance of the connection cables may result in
high-frequency discharge currents flowing to ground. The sum of the discharge
current and motor current may exceed the output-side rated current of PumpDrive.

Impairment of protection provided by enclosure when cable diameters other than those specified are used.
25)
Observe the information on the use of line chokes provided in the Accessories and Optional Equipment section.
26)
Max. cable cross-section: 0.75 mm² for the signal cables for digital inputs/field bus interface/+24 V DC supply, digital/analog
outputs
27)
Max. cable cross-section: 1.5 mm² for the signal cables for volt-free relays/analog inputs
28)
PWM carrier frequency at a max. ambient temperature of 40 °C: – Sizes A and B: 4 k Hz – Sizes B and C: 2.5 kHz
