 ==== High Voltage Relay Wiring – with Precharge ====
+⚠️ **Disclaimer – Safety First!** \\
+The wiring diagrams and connection examples provided here are **suggestions only** and may not cover all edge cases or safety requirements.\\
+All high-voltage components must be installed and verified by a **qualified electrician** or professional installer.\\
+Incorrect wiring or misuse can lead to **severe damage, fire, or personal injury**.\\

-      * **Negative Relay:**  Switches the low side (Battery -) to GND
+      * **Negative Relay:**  Switches the low side (Battery -)
   * **Precharge Resistor:**  Limits inrush current when first connecting to the inverter

+👉 We recommend using relays with economizer to avoid unnecessary load on the BMS power supply
 ''✅ Just plug in your relays – the BMS handles power and timing automatically''
