Please note the following:
 When selecting the power supply, please refer to the requirements
stated under “Technical Details”.
 Overvoltage or interference voltage can damage or even destroy the
electronics on the products PDP67 F 8DI ION HP, PDP67 F 8DI ION
HP VA. The affected outputs on the control system are shut down.
You should therefore take note of the relevant EMC measures.

WARNING!
Safe electrical isolation must be ensured for the 24 V supply.
Failure to do so could result in electric shock. Power supplies
must conform to EN 60950, section 2.3, EN 60742 or EN 50178.
 To achieve the lowest possible residual ripple, we recommend
that you install a three-phase bridge rectifier or regulated sup-
ply.
 The “Ground” connection to the earth bar or earth fault moni-
tor must be in accordance with the relevant national regula-
tions (e.g. EN 60204-1, NFPA 79:17-7, NEC: Article 250).
INFORMATION
The module's output circuits have been designed to guarantee
maximum safety. To achieve this, extensive tests are carried out
internally. Momentary interruptions to the “Supply” voltage dur-
ing a test procedure can falsify the test result, causing the fol-
lowing malfunction: If the “Supply” voltage is interrupted
momentarily, the unbuffered test pulse outputs will transmit a
“0” signal. The buffered module electronics reads this signal at
the pulsed inputs, thereby triggering the user's configured reac-
tion.
Example: The system reacts as though an E-STOP button has
been operated, although this is not the case: there has been a
supply interruption.
Remedy: The “Supply” must be buffered.
