After completion of the work or for test purposes, the power supply may only be
activated again by authorized personnel complying with the safety regulations.
WARNING:
Endangerment of electrical safety through power cable with
incorrect rating
Electrical accidents can occur when the specifications for replacement of a removable
power cable have not been adequately observed.
