Ensure the wiring and EMC requirements of EN 60204-1 are met.
}
Depending on which evaluation device is used, the overall cable resistance must be
checked; before commissioning it may also be necessary to check the cross circuit de-
tection function.
Perform the checks as described in the operating manual for the evaluation device.
} The safety contacts are not short circuit-proof.
} UL requirement: the supply voltage must be provided via a Class 2 power supply.
