Installation and operating instructions
Before assembly, verify the size of the mating piece (5.5×2.1 mm) and the required polarity of the device.
Solder the wires to the connector contacts, then check the mechanical securing of the cable in the strain relief.
After connection, we recommend checking the polarity and voltage with a multimeter before connecting the load.
Do not exceed the rated current and ensure adequate conductor cross-section.
Safety notice
The product is intended for low voltage DC applications within the specified range; do not use for mains voltage.
When soldering, follow safety precautions and avoid short circuits between contacts.
Incorrect polarity may cause damage to the powered device.
