5.2 Electrical installation
UL-Listing!
It is essential to observe chapter 3.3 if you wish to operate an AX5000 in an
economic area that requires a UL-Listing.
DANGER
Serious risk of injury through electric shock!
Due to the DC link capacitors dangerous voltage may persist at the DC link
contacts “ZK+ and ZK-“ and “RB+ and RB-“ after the servo drive has been
disconnected from the mains supply. After disconnecting the servo drive
wait at AX5160/AX5172 15 minutes, at AX5190/AX5191 30 minutes and at
AX5192/AX5193 45 minutes and measure the voltage at the DC link
contacts ZK+ and ZK-. The device is safe once the voltage has fallen below
50 V.
WARNING
Caution – Risk of injury through electric shock!
•
Before installation, wiring and commissioning it is essential to read the
section on "Safety".
• Before installing, uninstalling or connecting the servo drive and the
motors please note the following:
- Remove all relevant mains fuses.
- Switch off the main system switch and secure it with a lock.

• The control and power connections for the motors may be live, even if
the motor is prevented from rotating by the internal brake.
Attention
Destruction of the equipment!
•
Check the rated voltage and current of the servo drive and the connected
motors.
• When the AX5000 is disconnected from the mains supply (emergency
stop, mains contactor etc.), query the status of the IDN "P-0-0205" (see
