NCAN-02 Installation and Start-up Guide
4-1
Chapter 4 – Electrical Installation
Overview
This chapter contains:
• general cabling instructions
• module earthing instructions
• instructions of setting the module node number and communication
speed (baud rate)
• instructions for connecting the module to the drive and to the
CANopen bus.
WARNING!
Before installation, switch off the drive power supply. Wait
five minutes to ensure that the capacitor bank of the drive is
discharged. Switch off all dangerous voltages connected from external
control circuits to the inputs and outputs of the drive.
General Cabling
Instructions
Arrange the bus cables as far away from the motor cables as possible.
Avoid parallel runs. Use bushings at cable entries.
Handle the fibre optic cables with care. When unplugging optic cables,
always grab the connector, not the cable itself. Do not touch the ends
of the fibres with bare hands as the fibre is extremely sensitive to dirt.
The maximum long term tensile load for the fibre optic cables is 1 N.
The minimum short term bend radius is 25 mm.
Earthing the Module
The NCAN-02 module earth is connected to the rail onto which the
module is mounted. If the rail is fastened to an earthed metallic
assembly plate, the module is automatically earthed, and no external
earthing wire is needed. If the rail is fastened to a base that is not
earthed, the rail must be connected to the nearest earthing terminal.
However, the earthing wire should not be connected to the same
terminal as the power cable screens. (See the mounting instructions in
Chapter 3.)
