3.4.1. WiringtheCymbal

OncetheCymbalismounted,youarereadytowirethedevice.Properwiring,groundingand

Caution:Followtheseinstructionstoensuresafeandproperwiring:

• Usetwistedpairshieldedcablesforcontrol,feedbackandcommunicationconnections.For

bestresults,thecableshouldhaveanaluminumfoilshieldcoveredbycopperbraid,and

shouldcontainadrainwire.

Thedrainwireisanon‐insulatedwirethatisincontactwithpartsofthecable,usually

theshield.Itisusedtoterminatetheshieldandasagroundingconnection.

• Theimpedanceofthewiremustbeaslowaspossible.Thesizeofthewiremustbethicker

thanactuallyrequiredbythecarryingcurrent.A24,26or28AWGwireforcontroland

feedbackcablesissatisfactoryalthough24AWGisrecommended.

• Useshieldedwiresformotorconnectionsaswell.Ifthewiresarelong,ensurethatthe

capacitancebetweenthewiresisnottoohigh:C<30nFissatisfactoryformost

applications.

• Keepallwiresandcablesasshortaspossible.

• Keepthemotorwiresasfarawayaspossiblefromthefeedback,controland

communicationcables. 

• Ensurethatinnormaloperatingconditions,theshieldedwiresanddraincarrynocurrent.
