Start-up
Contents of this chapter
This chapter instructs how to start-up the unit.
Note: These instructions do not cover all possible cabinet constructions. Always refer to
the delivery-specific circuit diagrams when proceeding with the start-up.
WARNING! Only qualified electricians are allowed to do the work described in this
chapter. Read the complete safety instructions and repeat the steps described in
section Electrical safety precautions on page 128. The complete safety
instructions are given in Safety instructions for ACS880 multidrive cabinets and modules
(3AUA0000102301 [English]). Ignoring the instructions can cause physical injury or death,
or damage to the equipment.
WARNING! Before you activate the automatic fault reset or automatic restart
functions of the drive control program, make sure that no dangerous situations
can occur. These functions reset the drive automatically and continue operation
after a fault or supply break. If these functions are activated, the installation must be
clearly marked as defined in IEC/EN 61800-5-1, subclause 6.5.3, for example, “THIS
MACHINE STARTS AUTOMATICALLY”.
If you select an external source for the start command and it is on, the drive will start
immediately after fault reset. See the firmware manual.
Note: The customer is fully responsible for implementing and testing the functional safety
circuits according to the relevant legislation and acceptance testing regulations. The
functional safety option manuals give examples on implementing the safety circuits in
ACS880 multidrives. For information on the Safe torque off function, see chapter The Safe
torque off function.
