Fig 8 Wiring diagram KCE6000 19 Installation 3 2 1 Power Supply and Grounding The KCE6000 requires a regulated DC power supply of 24V 420 The power supply input of the KCE is protected by a 315mA fuse As a protection against fire in case of a short in the supply cable the output of the power supply must be equipped with a fuse with a rating not higher than the current carrying capacity of the cable used For connecting the KCE 6000 use shielded cables If several cables are used each cable should be shielded properly The ground pins of connector 1 05 1 08 and RS485 are internally connected together The supply pins of connector 1 05 1 08 and RS485 are internally connected together via ferrite inductances for EMI suppression For operating the KCE6000 the power supply can be applied to any of the 3 connectors NOTE The USB interface cannot be used to power the KCE6000 If a remote display KRD8000 is connected the display will be fed via the RS485 connector In that case use the connector VOS or 1 08 for powering the whole system See Fig 8 for connecting the power supply Ground GND and protective ground PE are internally connected via a 1kQ resistor The resistor will thermally withstand a potential difference of up to 30V between PE and GND but for proper operation this difference should be limited to 5V 3 2 2 Connecting the control inputs and outputs The frequency and control outputs are active push pu
