GROUNDING
The grounding of the MS26s system has an utmost importance for the protection of
the system against any lightning, or any high voltage coming through external lines,
extensions or mains.
For grounding the MS26s system, the ground location at the down left corner of the
MB26s motherboard (marked as M1) must be connected to a hot or cold water
pipe, which may serve as the ground surface of your system. For such cases, it is
of course better to construct an ideal ground, simply by inserting a metal bar (of at
least 1.5 m length and 1.5 cm radius, copper is preferable) into the earth, as
illustrated in the following figure.

PS38 POWER ADAPTOR
The PS38 Power Adaptor has an embedded mains plug for direct connection to the
mains outlet and a built-in cable (of 185 cm) for connection to the system.
For power connection :
1)
The 8-pin RJ plug at the free end of the cable must be passed through the
cable holes at the bottom part of the cabinet and connected to the POWER
socket on the MB26s motherboard.
2)
The adaptor must be plugged in the mains socket.
The following figure illustrates the connection of PS38 Power Adaptor.
