Safety
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death, or damage
to the equipment can occur. If you are not a qualified electrical professional, do not do
installation or maintenance work.
Checks/Settings with no voltage connected
Make sure that the disconnector of the supply transformer is locked to the off (0) position, that means
no voltage is, or cannot be connected to drive inadvertently.
Make sure that all external auxiliary circuits are switched off and disconnected. See the start-up instruc-
tions in the supply unit hardware manual.
Make sure that the supply unit is switched off, and the drive system has been isolated from the supply
network. Open the main disconnecting device of the drive: Crank in the main breaker ([Q1], option
+F255), or open the main switch/disconnector (F253).
Make sure that the DC switch/disconnectors [Q11] in inverter units and other units of the drive are
open and locked. Open and lock also the charging switches [Q10] (if any).
If the drive is equipped with a unit for an external energy storage connection (ACS880-1607LC or
ACS880-7107LC): Make sure that the disconnecting device of the energy storage (outside the drive)
is open and locked.
