C.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.
Power cables routing
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.
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.
Note: Run analog and digital signals in separate cables.
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.
Note: Check the insulation of the input power cable according to local regulations before
connecting to the drive.
