ABB SPIET800 Ethernet communication unit
This chapter states the safety instructions that must be followed wheninstalling and operating the NTAC-0x/NDIO-0x/NAIO-0x Module.
The material in this chapter must be studied before attempting any
work on, or with, the unit.
Warnings and Notes This manual distinguishes two sorts of safety instructions. Warnings
are used to inform of conditions which can, if proper steps are not
taken, lead to a serious fault condition, physical injury and death. Notes
are used when the reader is required to pay special attention or when
there is additional information available on the subject. Notes are less
crucial than Warnings, but should not be disregarded.
Warnings Readers are informed of situations that can result in serious physical
injury and/or serious damage to equipment with the following symbols:
Notes Readers are notified of the need for special attention or additional
information available on the subject with the following symbols:
Dangerous Voltage Warning: warns of situations
in which a high voltage can cause physical injury
and/or damage equipment. The text next to this
symbol describes ways to avoid the danger.
General Warning: warns of situations which can
cause physical injury and/or damage equipment by
means other than electrical. The text next to this
symbol describes ways to avoid the danger.
Electrostatic Discharge Warning: warns of
situations in which an electrostatic discharge can
damage equipment. The text next to this symbol
describes ways to avoid the danger.
CAUTION! Caution aims to draw special attention to a
particular issue.
Note: Note gives additional information or points out
more information available on the subject.

WARNING! All electrical installation and maintenance work on the
drive should be carried out by qualified electricians.
The drive and adjoining equipment must be properly earthed.
Do not attempt any work on a powered drive. After switching off the
mains, always allow the intermediate circuit capacitors 5 minutes to
discharge before working on the frequency converter, the motor or the
motor cable. It is good practice to check (with a voltage indicating
instrument) that the drive is in fact discharged before beginning work.
The motor cable terminals of the drive are at a dangerously high
voltage when mains power is applied, regardless of motor operation.
There can be dangerous voltages inside the drive from external control
circuits even when the drive mains power is shut off. Exercise
appropriate care when working with the unit. Neglecting these
instructions can cause physical injury and death.
WARNING! There are several automatic reset functions in the
drive. If selected, they reset the unit and resume operation after a fault.
These functions should not be selected if other equipment is not
compatible with this kind of operation, or dangerous situations can be
caused by such action.
More Warnings and Notes are printed at appropriate instances along
the text.
