DANGER!
While the devices are in operation there is a risk of death or serious in-
jury and material damage.
- Do not open or touch the devices during operation.
- Keep all covers and cabinet doors closed during operation.
- When the devices are switched on, they should only be touched during
commissioning by qualified staff.
- During operation the servo amplifiers may contain live, uninsulated com-
ponents, depending on their protection type.
- Control and power connections may still carry voltage, even when the mo-
tor is not rotating.
- Surfaces on the servo amplifiers may become hot during operation. Tem-
peratures may reach more than 80° C.
DANGER!
In unfavourable conditions arcing may occur, causing potential injury
to persons and damage to electrical contacts.
For this reason, never unplug the electrical connections on the servo ampli-
fier while voltage is applied.
After disconnecting the servo amplifier from the mains voltages, wait at least
five minutes before touching any parts that carry voltage (e.g. contacts) or
loosening the connections.
After the mains voltages have been switched off, capacitors continue to
carry hazardous voltages for up to 5 min.
To be safe, measure the voltage in the intermediate circuit and wait until the
voltage has dropped below 40 VDC.
DANGER!
While the devices are in operation there is a risk of death or serious in-
jury and material damage.
When the supply voltage is switched on, do not:
- Open the housing
- Connect or disconnect connection terminals
- Connect or disconnect a connection wiring
- Install or remove accessories
