This manual contains clearly marked cautions and warnings which are intended for your personal safety
and to avoid any unintentional damage to the product or connected devices.
Please read the information included in cautions and warnings carefully.
The cautions and warnings are marked as follows:

Danger

The components of the power unit of Siemens BT300 are live when the AC drive is con-
nected to the primary input voltage. Coming into contact with this voltage is extremely
dangerous and may cause death or severe injury.
9000.emf
The motor terminals U, V, W are live when Siemens BT300 is connected to mains, even if
the motor is not running.
9000.emf
After disconnecting the AC drive from the mains, wait until the indicators on the keypad
go out (if no keypad is attached see the indicators on the cover). Wait 5 more minutes
before doing any work on the connections of Siemens BT300. Do not open the cover
before this time has expired. After expiration of this time, use a measuring equipment to
9000.emf
absolutely ensure that no
starting any electrical work!
The control I/O-terminals are isolated from the mains potential. However, the relay out-
puts and other I/O-terminals may have a dangerous control voltage present even when
Siemens BT300 is disconnected from mains.
9000.emf
Before connecting the drive to mains make sure that the front and cable covers of Sie-
mens BT300 are closed.
9000.emf
During a coast stop (see the Application Manual), the motor is still generating voltage to
the drive. Therefore, do not touch the components of the AC drive before the motor has
completely stopped. Wait until the indicators on the keypad go out (if no keypad is
attached see the indicators on the cover). Wait additional 5 minutes before starting any
9000.emf
work on the drive.

voltage is present.
Always ensure absence of voltage before
