Engineering reference

## Choosing the right IR7 configuration.

Confirm the gas or dust classification first, then select the strip count and wattage. Maes Lighting will confirm the required output, current listing file, mounting method and optional emergency battery for the project.

IR7 scales by strip count: two strips at 80 W through six at 240 W. The family uses one enclosure size, 120-277 V input, surface or suspended mounting, and four mounting options. Confirm the required output for the ordered catalog number.
