General Safety Instructions
• Individually insulate all unused ends of the output signals to avoid short-
circuit.
• When assembling the cable mating connector, comply with the
instructions that are attached to the connector.
• Only connect or disconnect the mating connector to or from the encoder
when the encoder is disconnected from the power supply.
• Electrostatic discharges at the contacts of the connector or at the cable
ends could damage or destroy the device. Take appropriate precautionary
measures.
• Make sure that the operating voltage is switched on and off simultaneously
for the encoder and the downstream device.
• Comply with the proper operating voltage and the maximum admissible
output current.
• Use a PELV supply voltage source according to IEC 60204-1. To meet UL
requirement, a Class 2 power supply is required for North America.
ATTENTION:
• Make sure that the operating voltage is switched on or off simultaneously
for the encoder and the downstream device.
• Electrostatic discharges at the contacts of the connector or at the cable ends
could damage or destroy the device. Take appropriate precautionary
measures.
• Use a PELV supply voltage source according to IEC 60204-1 complying with
the proper operating voltage and the maximum permissible output current.
To meet UL requirement, a Class 2 power supply is required for North
America.
IMPORTANT To connect the encoder, refer to the corresponding operating and safety
instructions of the external drive system/encoder evaluation system.
When assembling a mating connector, comply with the instructions that are
attached to the connector.
IMPORTANT Verify that all required cable wires/connectors are connected before
commissioning. Insulate individually all unused ends of the output signals to
avoid short-circuits.
ATTENTION: Commissioning requires a thorough check by authorized
personnel.
Before you operate a system that is equipped with the 843ES CIP Safety
absolute encoder, verify that authorized personnel check and release the
system.
