FEATURES OVERLAY
The DMS-6 D-Clock-R is designed for standard 19" rack
mounting and occupies 1U of rack space. Avoid mounting
the unit directly above power amplifiers or power supplies
that radiate significant amounts of heat.
If the unit is to be used in a mobile situation, it is strongly
recommended that the rear of the unit is supported in the
carrying rack to avoid bending the front panel rack mounting
‘ears’. Use fibre or plastic washers to prevent the front panel
becoming marked by the mounting bolts.
Always connect the mains earth to the unit.
INSTALLATION
The DMS-6 D-Clock-R is fitted with two identical and
independent power supply units, providing Dual
Redundancy. Either can be used solely to supply power
to the unit, but in situations where it is critical that power
must be maintained mains power should be supplied to
both units. With both power supplies receiving power the
units will share the load, however, should either fail, the
other is capable of fully driving the unit.
The unit will be supplied with two power cables
suitable for domestic power outlets in your country.
For your own safety it is important that you use
these cables. The unit should always be connected
to the mains supply earth using at least one of these
cables.
Powered by dual universal switch mode power supplies,
the DMS-6 D-Clock-R operates from mains voltages
between 85 - 250v, eliminating the need to make any
changes when touring and allowing the unit to remain fully
operational during large fluctuations in the mains power
supply.
POWER CONNECTION
Active PSU LED’s:
Two led’s showing which of the two
PSU inputs 9 is operational.
