This unit is warranted by ASL Intercom to the

workmanship and materials in it’s manufacture
for a period of 12 months from date of

the original suppliers invoice.
Adequate ventilation must be provided by

rear of the unit to ensure free circulation of air.
Forced cooling is not required. The power

After a period of time the unit will feel hot to the
touch at the top and the bottom; this is normal
and should be no cause for alarm. To connect

professional flexible microphone cable with 2
wires and 1 shield only.
Connect these cables to the INTERCOM OUT
connectors on the rear panel.
The PS 6379 Mk2 is fully protected against
wiring mistakes (e.g. reverse power) or short
circuit in the interconnect cables. Included in
the shipping carton is a kit for mounting the
unit in a 19" rack, taking 2U of rack-space.
6.0 MAINS POWER & SAFETY EARTH
Connecting to mains power :
The PS 6379 Mk2 may be connected to a mains
power outlet which provides 100 – 240 V AC, 50-
60 Hz, 200 watts. The outlet should have a clean
earth. Avoid using mains power outlets which
also power dimmer controlled lighting equipment.
The wires in the mains lead are color coded:
green/yellow: Earth / safety ground
blue: Neutral
brown: Live
In case the wires in the mains lead do not
correspond with the colored markings identifying
the terminals in your mains plug, proceed as
follows:
• The wire which is colored green/yellow must be
connected to the terminal in the plug which is
marked with the letter “E”, or by the ground
symbol, or is colored green.
• The wire which is colored blue must be
connected to the terminal which is
marked with the letter “N” or colored
black.
• The wire which is colored brown must be
connected to the terminal which is
marked with the letter “L” or colored red.
Safety Earth :
The green/yellow wire of the mains lead must
always be connected to the electrical
installation safety earth or ground. This is
essential for personal safety as well as for proper
operation of the PS 6379 Mk2 and the connected
stations. The green/yellow wire is in the PS 6379
Mk2 connected to all exposed metal surfaces.
Any rack framework into which this unit might be
mounted is assumed to be connected to the
same grounding circuit.
