Electrical installation
What this chapter contains
This chapter describes the electrical installation procedure of ACS800-104 inverter
modules.
The wiring diagrams in this chapter are simplified presentations. See the chapter
Circuit diagrams for details.
General
WARNING! Make sure that the drive system is disconnected from the mains (input
power) during installation. If the drive system is already connected to the mains, wait
for 5 min after disconnecting mains power. Measure the voltage between the L+ and
L– terminals with a multimeter (impedance at least 1 Mohm) to ensure that the drive
system is discharged before beginning work.
WARNING! Circuit boards contain components sensitive to electrostatic discharge
(ESD). Wear an earthing wrist band when handling the boards. Do not touch the
boards unnecessarily.
Notes on Optical Components
Handle 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 specifications of the optic cable are as
follows:
• Storage temperature: -55 … +85 °C
• Installation temperature: -20 … +70 °C
• Maximum short-term tensile force: 50 N
• Minimum short-term bend radius: 25 mm
• Minimum long-term bend radius: 35 mm
• Maximum long-term tensile load: 1 N
• Flexing: Max. 1000 cycles
ABB drive products in general utilise 5 and 10 MBd (megabaud) optical components
from Agilent Technologies’ (Hewlett-Packard) Versatile Link range. Please note that
the optical component type is not directly related to the actual communication speed.
