9. FRONT SIDE AND USER ELEMENTS
Fig. 9-1 Front side
A
Input terminals
Screw terminals
+ Positive input
- Negative (return) input
Chassis ground: can be used to bond the housing to PE
Ground this terminal to minimize high-frequency emissions.
B
Output terminals
Screw terminals, dual terminals per pole, both pins are equal
+ Positive output
- Negative (return) output Screw terminals
C
Output voltage potentiometer
Open the flap to set the output voltage. Factory set: 12.0V
D
DC-OK LED (green)
On when the voltage on the output terminals is > 8.5V
Mar. 2016 / Rev. 1.5 DS-CD5.121-EN
All parameters are specified at 12V, 8A, 24Vdc input voltage, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.
