D.4.2 Control cables
All analog control cables and the cable used for the frequency input must be shielded. Use a
double-shielded twisted pair cable (Figure a) for analog signals. Employ one individually
shielded pair for each signal. Do not use common return for different analog signals.
A double-shielded cable is the best alternative for low-voltage digital signals, but a
single-shielded or unshielded twisted multipair cable (Fig b) is also usable. However, for
frequency input, always use a shielded cable.
Note: Run analog and digital signals in separate cables.
The relay cable needs the cable type with braided metallic screen.
The keypad needs to connect with cables. It is recommended to use the screen cable on
complex electrical magnetic condition.
Do not make any voltage tolerance or insulation resistance tests (for example hi-pot or
megger) on any part of the drive as testing can damage the drive. Every drive has been
tested for insulation between the main circuit and the chassis at the factory. Also, there are
voltage-limiting circuits inside the drive which cut down the testing voltage automatically.
Check the insulation of the input power cable according to local regulations before
connecting to the drive.
