Installation
WARNING: Allowed mounting position: To ensure proper ventilation during operation, only vertical wall mounting is allowed for
the DIN rail power supply. Horizontal mounting is not allowed.
1.
Mounting location: Keep the ventilation slots of the DIN rail power supply free at the top and bottom (20-40mm). Sufficient
space around the power supply at the mounting location (5-10mm) must be provided in order for it to cool properly.
2.
Tilt the power supply slightly backwards and place it on the rail from above.
3.
Push the power supply down as far as it will go.
4.
To lock the power supply in its place, press against the lower front until it clicks into the rail (it makes a click sound).
5.
Gently shake the power supply to check that it is securely attached.
Wiring
WARNING: Danger! The connection must be made in a voltage-free/load- free state!
WARNING: Use separate wires for the inputs and outputs.
WARNING: The DIN rail power supply works as soon as the primary side is receiving voltage. It does not have its own on/off switch.
We recommend checking the output voltage once with a multimeter before connecting a device, because an unwanted output
voltage could damage or destroy your device.
1.
Open all screw terminals (+, -, L, N) with a flathead or crosshead screwdriver.
2.
Route the cables in the cable holders and fasten the screw terminals again, so the cables are firmly secured.
3.
Check that the cables are firmly secured.
Adjusting the output voltage
Above the symbol "+V ADJ" on the power supply you will find the potentiometer for adjusting the output voltage (for values see
table). The output voltage can be increased by turning it clockwise with a flathead or crosshead screwdriver.
Disassembly
WARNING: Before removing, switch off the main power supply, check that there is no voltage present and disconnect the power
supply from the mains.
1.
Put a flathead screwdriver into the groove of the release slide (at the bottom of the power supply) and pull it downwards with it.
2.
Lift the lower front edge of the power supply carefully and remove it.
Malfunction
WARNING: A functional test may only be carried out by qualified electricians.
Should a malfunction occur, check the following:
•
Is the LED ("Output voltage OK") lit (except 1010427)?
•
Are the cables for the nominal input voltage (L, N) connected?
•
Is the protective earth (PE) connected?
•
Is the shielding/ground of the power supply cable connected to the device?
•
Is the device connected to the output with the correct polarity?
•
Has the correct cable diameter been selected?
•
Is the nominal output voltage (5V/12V/24V, see table) correctly applied to the input of the device?
•
Has the maximum output current been exceeded by too many devices?
