Installation
• Only qualified personnel is allowed install and perform the connection of PDD-300 into
customer's system
• PDD-300 is intended only for diode driving applications. The module should only be
used inside the medical equipment, which has means to isolate its circuits electrically
from the supply mains on all poles simultaneously
• Use four M4 mounting slits on the bottom side of PDD-300 to fix the module in your
system. Refer to the Dimensional drawing section for their location
• There is no preferred driver orientation, it can be mounted in normal position, upside-
down position or in other orientations, as well
• Connect the module to your system protective ground using provided M5 grounding stud
• Connect AC INPUT, OUTPUT and INTERFACE cables according to their functions
• Since module is air cooled, at least 50mm of free space should be provided both at the
suction and pressure sides of PDD-300
Operations notes
1. The proper sequence of driver's start up procedure is 'power -> enable -> pulse'. Other
sequences are considered as incorrect
2. When driver is powered but disabled, the fan rotates slowly;
once driver is enabled, the fan will accelerate to a higher speed
3. Fault state is set when fault condition is met AND driver is enabled
4. To remove Fault state one should disable driver and enable it again
Troubleshooting
• In case of a mains voltage interruption, the output voltage drops down. Once the mains
voltage is restored, the unit doesn't restart automatically and needs to be enabled again to
resume the operations.
