66 Guidelines for planning the electrical installation Control panel cable length and typeIn remote use, the cable connecting the control panel to the drive must not exceed threemeters (10 ft). Cable type: shielded CAT 5e or better Ethernet patch cable with RJ-45ends. Routing the cablesRoute the motor cable away from other cable routes. Motor cables of several drives can berun in parallel when installed next to each other. The motor cable, input power cable andcontrol cables should be installed on separate trays. Avoid long parallel runs of motorcables with other cables in order to decrease electromagnetic interference caused by therapid changes in the drive output voltage.Where control cables must cross power cables, make sure they are arranged at an angleas near to 90 degrees as possible. Do not install extra cables through the drive.The cable trays must have good electrical bonding to each other and to the groundingelectrodes. Aluminum tray systems can be used to improve local equalizing of potentialA diagram of the cable routing is shown below.DriveMotor cablePower cableMotor cable, brake cableControl cablesControl cablesInput power cablemin 200 mm (8 in.)min 300 mm (12 in.)min 500 mm (20 in.)90 °
