In the “MultiPlus” and the “MultiPlus II GX” manuals, it states:
“The device can be fitted either horizontally or vertically. For optimal cooling, vertical fitting is preferred.”
But the MultiPlus II (12/3000/120-50 2x120V) manual does not address horizontal, nor does it prohibit it.
Can the MultiPlus II (12/3000/120-50 2x120V) be mounted horizontally in a cool environment?
