6.1 General Notes on Startup and Operation
CAUTION
Risk of electric shock if the protective earth conductor is not connected!
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the N-470 in the case of malfunction or failure of the system. If touch voltages exist,
touching the N-470 can result in minor injuries from electric shock.
 Connect the N-470 to a protective earth conductor before startup.
 Do not remove the protective earth conductor during operation.
 Establish contact between the N-470 and the protective earth conductor via a sufficiently
conductive mechanical mounting (p. 19).
 Make sure that the contact resistance is <0.1 Ω at 25 A at all connection points relevant for
mounting the protective earth conductor.
 If the protective earth conductor has to be removed temporarily (e.g., in the case of
modifications), reconnect the N-470 to the protective earth conductor before starting it up
again.
NOTICE
Operating voltage too high or incorrectly connected!
Operating voltages that are too high or incorrectly connected can cause damage to the N-470.
 Operate the N-470 only with controllers/drivers and original accessories from PI.
 Do not exceed the operating voltage range (p. 37) for which the N-470 is specified.
 Operate the N-470 only when the operating voltage is properly connected; see "Pin
Assignment" (p. 46).
