Input
The device must be installed in accordance with EN 60950 regulations. It must be possible to disconnect the device using a
suitable isolating facility outside of the power supply, such as the Primary side line protection. An internal fuse provides
device protection; no additional device protection is necessary.
Caution
The recommended backup fuse for Mains protection is power circuit-breaker 6 A, 10 A, or 16 A, characteristic B or identical
function.
Attention
Output
Caution
Connection is established using the screw connections on the DC output as follows:
• 24 V dc: + and –
• Active DC OK switching output: DC OK LED and –
• Floating DC OK output: 13 and 14
• Active POWER BOOST switching output: I < I
The default output voltage is 24 V dc. However, output voltage may be modified using the potentiometer.
The device is electronically protected against short-circuit and idling. If a malfunction occurs, the output is limited to 35 V dc.
PDM Power Distribution Modules
If an internal fuse is triggered, there may be a malfunction with the device. Return the
device to the GE for inspection.
Be sure to connect a suitable fuse upstream for DC applications.
Make sure that all output lines are dimensioned according to the maximum output
current or they are separately protected. The cables on the Secondary side must have
sufficiently large cross sections to keep the voltage drops on the lines as low as
possible.
