1: Introduction. The SC0180 Transient Suppression Module is intended to be used in environments where severe electrical transient and disturbances are encountered. The module will protect the encoder from malfunctioning due to disturbances coming through the cable. The module should be connected between the encoder cable and the connection cable and should be mounted as close as possible to the encoder. > Rev. 1.0 ֖ 14-07-08 Page 1 of 3 >

3: Shield Connection. The module has an option for either leaving the encoder cable shield unconnected (isolated) or connecting the encoder cable shield/housing to the connection cable. If the Shield jumper is not mounted, the encoder will be isolated from the connection cable shield ( > Mounting Option A ). If the Shield jumper is mounted, the encoder shield will be connected to the connection cable shield ( > Mounting Option B ). Note -- for the encoder to be truly isolated, the encoder housing and the shaft must also be isolated from the local ground (machine part). It is difficult to give...
