Rack Mount Installation. The M3 chassis has four rack mounting holes in its chassis and has been
designed to fit in a 19” standard 2RU space. Plastic ‘finishing’ washers are recommended to protect
the painted finish around the mounting holes.

power entry module to an AC mains outlet with a functional earth ground connection. The M3 has been
set at the factory to operate at 120VAC unless otherwise specified on the shipping carton. Please
connect your M3 to an uninterruptible power supply (UPS) to protect against power surges and
brownouts.
