MAINS POWER & SAFETY EARTH
The BS 217 may be connected to a mains power outlet which provides 100 – 240 V AC, 50-
60 Hz and at least 60 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 in accordance with the following code:
Green/ yellow:
Earth / safety ground
Blue:
Neutral
Brown:
Live
In case the colors of the wires in the mains lead do not correspond with the colored mark-
ings identifying the terminals in your plug, proceed as follows:
The wire which is colored green-and-yellow must be connected to the terminal in
•
the plug which is marked with the letter "E", or by the earth 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 is colored black.
The wire which is colored brown must be connected to the terminal which is
•
marked with the letter "L" or is colored red.
Safety Earth
The green-and-yellow wire of the mains cord must always be connected to the elec-
trical installation safety earth or ground!
This is essential for personal safety as well as for proper operation of the BS 217 and the
other connected stations. The green/yellow wire is in the BS 217 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.
