Connections
Figure 2-1 Rear panel - Connections
Connection to your station must be accomplished in the order described below, before you apply mains
voltage to the amplifier.
Before you connect the amplifier to external grounding, you should advise with a
licensed electrician and confirm such kind of connection is allowed by your national and
local electrical code, safety rules, and regulations in force. Simultaneous connection to
the earth grounding and protective earth may be inadmissible or may fall under special
requirements in some countries!
DANGER
Never use the gas installation pipes for grounding. This can cause an EXPLOSION!
DANGER
Do not use the steam-heating or water-supply network pipes for grounding! You may
expose to dangerous voltage not only yourself but also other people using the same
installation.
WARNING
Note that the grounding system may have to withstand currents over 15 A with
insignificant voltage drop on it. Therefore, it may be necessary to improve it
considerably, i.e. to become less resistive, with heavier leads and lower-resistive ground
path. The grounding leads should be at least 4 mm

(AWG 11 or SWG 13).
a)
GND stud
First, connect the wing-nut grounding stud of the amplifier (on the rear panel, marked
GND
) to the station's
grounding system (see
Figure 2-1 Rear panel - Connections
).
