4.1 Introduction
Thiss ection describes the input and output connections of the DS M.
Logiclev el cables must not run parallel to power cables. Power cables willintroduc e noise into
thelogic levelcables and make thesystem unreliable.Logic lev el cables must be shielded to
reducethe c hance of induced noise. The shield needs to be grounded at the signal sourc e to
ACground; the other end of the shield mus t not be connected. This allows the shield to act as
adrain.
Donot connec t or disconnect any wiring when power is applied! Disconnec t the
ACpower sideto power downthe DC pow er supply. For battery operated
systems,connect a transient suppres sor across the power switch to prev ent arcs
andhigh voltage s pikes.
