9.3 Inspection and maintenance work
9.3.1 Preliminary work regarding inspection and maintenance
Observe the following notes before you start with inspection/maintenance work:
WARNING
Risk of injury if the device starts up unintentionally, and danger of electrical voltage.
Dangerous voltages may still be present for up to 5minutes after disconnection from
the line voltage.
• Disconnect the device from the power supply with suitable external measures be-
fore you start working on the device and secure it against unintentional reconnec-
tion to the voltage supply.
• Secure the output shaft against rotation.
• Before removing the electronics cover, wait for at least the following time:
5minutes.
WARNING
Risk of burns due to hot surfaces and hot gear unit oil.
Serious injuries.
• Let the devices cool down before touching them.
• Remove the screw plugs and the breather valve carefully.
• The gear unit must still be warm, otherwise the high viscosity of excessively cold
oil will make it more difficult to drain the oil correctly.
NOTICE
Damage to the drive unit.
Potential damage to property.
• Make sure that only the SEW‑EURODRIVE Service or qualified personnel
trained by SEW‑EURODRIVE opens the gear unit cover.
NOTICE
Filling in the wrong oil may result in significantly different lubricant characteristics.
Potential damage to property.
• Do not mix different synthetic lubricants and do not mix synthetic and mineral lu-
bricants.
• Synthetic oil is used as the standard lubricant.
