4 Electrical Installation
Many cable management features have been incorporated into the
product and accessories, this chapter shows how to optimize them. Key
features include:
•
EMC compliance
•
Product rating, fusing and cabling information
•
External suppressor resistor details (selection / ratings)
Electric shock risk
The voltages present in the following locations can cause
severe electric shock and may be lethal:
•
AC supply cables and connections
•
DC cables, and connections
•
Many internal parts of the drive, and external option
units
Unless otherwise indicated, control terminals are single
insulated and must not be touched.
Isolation device
The AC supply must be disconnected from the drive using
an approved isolation device before any cover is removed
from the drive or before any servicing work is performed.
STOP function
The STOP function does not remove dangerous voltages
from the drive, the motor or any external option units.
Drives are suitable for use on supplies of installation
category III and lower, according to IEC60664-1. This means
they may be connected permanently to the supply at its
origin in a building, but for outdoor installation additional
over-voltage suppression (transient voltage surge
suppression) must be provided to reduce category IV to
category III.
