All connections are made via screw terminals. Refer to the product label for exact terminal markings. Ensure all wires are correctly sized for the current draw and securely fastened to prevent loose connections.

• Input Terminals (AC): Connect the AC input (90-264 VAC) to the designated 'L' (Line), 'N' (Neutral), and 'FG' (Frame Ground) terminals.
• Output Terminals (DC): Connect the DC load to the '+V' (Positive) and '-V' (Negative) terminals.
• Topraklama: Proper grounding is essential for safety and performance. Connect the frame ground terminal to an earth ground.

Recommended torque for screw terminals is typically 4.4 lb-in for input and 7 lb-in for output, but always refer to the specific markings on the unit.

5. Kurulum

5.1. Çıkış Hacmitage Ayarlama

The NDR-240-24 features an adjustable output voltage. Locate the '+V ADJ' potentiometer on the unit. Using a small screwdriver, carefully turn the potentiometer clockwise to increase the output voltage or counter-clockwise to decrease it. The factory setting is typically 24V, with a small adjustment range (e.g., 24.2V).

5.2. İşlem Öncesi Kontrol

Before applying power, double-check all wiring connections for correctness and security. Ensure no loose strands or short circuits are present.

6. Kullanım Talimatları
