C.3.2 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 multi-pair cable (Figure 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 cables according to local regulations before connecting
the cables.

Note:
1. It is appropriate to use the recommended cable size under 40
between the inverter and the motor should be no more than 50 m without using any filter and between 50~100m
using chokes. It is possible to have longer distances if a sine wave filter is installed.
2. Terminals P1, (+), PB and (-) can be used to connect an optional DC reactor.
