ton, and visually inspected before leaving our manufacturing facility. If you receive the inverter in a
damaged shipping carton, please reject the shipment and notify the shipping company.
Verify Delta M series shipping carton contains:
a. Correct Delta M series inverter model: M4-TL-US,M5-TL-US,M6-TL-US, M8-TL-US ,and M10-
TL-US
b. Mounting plate
c. Operation and installation manual
Visually inspect the Delta M series inverter for any physical damage such as a bent heatsink fin
and dented chassis.
If the inverter appears to be damaged or if the inverter needs to be returned, please contact your
local Delta representative.

Installation location

1. Install the inverter on a non-flammable support base.
2. The inverter must be mounted vertically on a flat surface.
3. A minimum distance of 6 inches (15.2 cm) of unobstructed clearance on all sides to promote
free convection is required.
4. Ensure the mounting hardware and structure can support the weight of the inverter.
5. Ensure the mounting hardware meets the appropriate building code.
6. Avoid installation on resonating surfaces (light construction walls etc.).
7. Installation can be indoors or in protected outdoor areas.
8. Avoid direct sun exposure.
9. Ensure inverter ambient temperature is within -13°F to +122°F (-25°C to +45°C) for optimal
efficiency of the PV system.
10. Chose a mounting height for easy viewing of the display.
11. Despite having a NEMA 4 (NEMA 3R for wiring box)enclosure with a soiling category III
certification, the inverter must not be exposed to heavy soiling.
12. Unused connectors and interfaces must be covered through sealing connectors.
No user serviceable parts are contained in the inverter section.
Do not attempt to open or repair the inverter. The inverter section
is factory sealed to maintain its NEMA 4 rating and opening the top
cover of the power head will void the inverter warranty.
Ne tentez pas d'ouvrir ou de réparer l'onduleur. La section de
l'onduleur est scellée en usine afin qu'elle conserve son courant
nominal NEMA 4, son ouverture annulerait la garantie.
