8.1 MOUNTING
The MDC-360 is intended for rack mounting. For maximum operating ease it
should be mounted at approximately eye level. If the MDC-360 is mounted in a
rack containing other heat generating equipment, care should be taken that there is
adequate ventilation to assure that the ambient temperature does not exceed the
MDC-360’s ambient temperature rating.
The MDC-360 was designed for maximum noise nd in most cases will
require no spec unding precaut ent that noise sensitivity is

8.3 EXTER CONNECTIO
Most external connections are made he rear panel (See Figure 8-2). The
Remote Power H set connector an S-232 connection are,
however, located on the front panel (Figure 8-1).

The power receptacle is an internatio ype. A fuse, voltage
ower plug must be removed to change the fuse or the voltage selection board
position.
8.3.2 VO TION
The voltage selection is preset at the a nominal input of 120 volts.
However, the following nominal inpu e selected: 100, 120, 220,
