Installation and Mounting / Front Panel Controls

INSTALLATION AND MOUNTING NOTES

This equipment is designed to be installed in a standard 19" rack. When the unit is mounted above or below other rack

mounted equipment, a 1U space (1.75") should be left between the unit and the other equipment to allow ambient air flow

between the units. No space is needed between EH24 units themselves due to the ventilation provided by their built in fans.

Connect the AC line cord to an appropriate source of 120 volt, 50/60 Hz AC power. The EH24 is always on once the AC

power cord is connected to its power source.
