NIBA-01 Installation and Start-up Guide

Chapter 4 – Electrical Installation
Overview
This chapter contains:
•
Cabling instructions
•
Connection and earthing instructions for the NIBA-01 Module and
earthing instructions for the bus cable.
WARNING! Before installation, switch off the drive power supply. Wait
for 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.
Cabling
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 cable is 1 N.
The minimum short term bend radius is 25 mm.
The NIBA-01 module is connected to the drive using a fibre optic cable
link. Consult the drive documentation as to the corresponding terminals
inside the drive.
