7.1 Safety
Incorrect supply voltage
WARNING!
Equipment damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the equipment.
For this reason:
• Only operate the distance measuring device using a protected low voltage and safe electrical insulation as per protection class III.
Working with live parts
WARNING!
Equipment damage or unpredictable operation due to working with live parts.
Working with live parts may result in unpredictable oper-ation.
For this reason:
• Only carry out wiring work when the power is off.
• Only connect and disconnect cable connections when the power is off.
7.2 Wiring instructions
WARNING!
Faults due to incorrect wiring!
Incorrect wiring may result in operational faults.
For this reason:
• Only use shielded cables with twisted-pair wires.
• Follow the wiring instructions closely.
Electrical connection
WARNING!
Risk of damage to the device resulting from a
non-grounded supply voltage or equipotential bonding currents!
A non-grounded supply voltage or potential differences between the supply voltage GND and the distance mea-suring device housing may result in the device sustaining damage.
For this reason:
• Only operate with a grounded supply voltage.
• Ensure low-impedance and current-carrying equipoten-tial bonding.
NOTE!
→ For pre-assembled cables, see Page 79, Chap-ter 14.2.
All electrical connections of the DL100 Pro distance measuring device are configured as M12 round connectors.
The male connectors of the distance measuring device are compatible with SpeedCon™ quick connectors and standard M12 screw connectors.
The shields of the EtherCAT® cables are connected together using the EtherCAT® connectors.
The IP65 protection class is only achieved with screwed plug connectors or cover caps.
Please observe the following wiring instructions:
• A correct and complete cable shielding concept is required for trou-ble-free operation.
• The cable shield must be connected at both ends in the control cabinet and at the measuring device. The cable shield of the pre-assembled cables is connected to the knurled nut and thus also to the measuring device housing.
• The cable shield in the control cabinet must be connected to the operat-ing ground over a large surface area.
• Appropriate measures must be taken to prevent equipotential bonding currents flowing through the cable shield.
• Do not lay cables parallel to other cables, especially not to devices with a high level of radiated emission such as frequency converters.
