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.
