3. Page 2 CABLE PROTECTION Run the encoder cable through a dedicated conduit not shared with other wiring Use of conduit will protect the cable from physical damage and provide a degree of electrical isolation If a conduit is not practical use wire trays to protect cable If there is not a practical way to protect the cable you may consider using armored cable See section 9 of the IEC EN60079 14 standard as applies to Increased Safety installations Do not run the cable in close proximity to other conductors that carry current to heavy loads such as motors motor starters contactors etc This practice can induce electrical transients in the encoder cable potentially interfering with reliable data transmission CAUTION Unused encoder signal wires must be individually insulated and under no circumstances be in contact with ground voltage sources or other signal lines Zone 1 Wiring Considerations CAUTION The Encoder wiring configuration for the EN series encoder is different than an Intrinsic Safe wiring configuration No IS barrier Zener or Galvanic is required when using the EN series encoder Barriers may prevent proper operation and or frequency performance Damage to the encoder may occur if the encoder output is connected to an IS barrier When selecting an encoder consider the power supply to the encoder and input voltage to your data acquisition PLC or drive system Cable length and RPM max will determin
