Delta M80U User Manual

Surge protection devices (SPD) are designed to protect sensitive circuit
elements of the inverter from damage caused by lightning and other electrical
transients/surges, as such they are sacrificial components and periodically,
may need replacement.
The SPDs are located in the inverter wiring box (WB) on both AC and DC input
terminals. If a warning message “AC Surge” or “DC Surge” appears on display
panel, follow the procedure below to replace the SPD.
• Determine which SPD unit is damaged. See Figure 5-4.
AC SPD: “AC Surge” with show on the corner of the LCD panel.
