2.8 Startup/operation
Risk of burns: The surface temperature of the product can exceed 60°C during opera-
tion. Do not touch the product during operation. Let the product cool down before
touching it.
Do not deactivate monitoring and protection devices of the machine or system even
for a test run.
Depending on the degree of protection, products may have live, uninsulated, and
sometimes moving or rotating parts, as well as hot surfaces during operation.
Make sure that any existing transport protection is removed.
In the event of deviations from normal operation, switch the product off. Possible devi-
ations are increased temperatures, noise, or vibration, for example. Determine the
cause. Contact SEW‑EURODRIVE if necessary.
Ensure that the terminal box is closed and screwed down before applying the supply
voltage.
Additional preventive measures may be required for applications with increased haz-
ard potential. Be sure to check the effectiveness of the protection devices after every
modification.
Mechanical blocking or internal protective functions of the product can cause a motor
standstill. Eliminating the cause of the problem or performing a reset may result in the
drive restarting automatically. If, for safety reasons, this is not permitted for the drive-
controlled machine, first disconnect the product from the supply system and then start
troubleshooting.
