Operating instructions Distance measuring device DL100 – CANopen®
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dierences
between the supply voltage GND and the distance
measuring 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!
→ Ready-made cables, see page 134, chapter 15.2.
All electrical connections of the distance measuring device DL100 are M12
round plugs.
The connection plugs of the distance measuring device are compatible to
the SpeedCon™-quick connections and standard-M12 screw connections.
Protection class IP65 is only achieved with screwed plug connectors or
cover caps.
Observe the following notes for wiring:
• A proper and complete shielding concept is required for interference-free
function.
• The cable shield must be applied on either side in the control cabinet
and the measuring device. The cable shield of the ready-made cables is
connected to the knurled nut and thus the measuring device casing.
• Connect the cable shield in the control cabinet with the operating
ground on a large cross-section.
• Potential balancing currents through the cable shield must be prevented
by suitable measures.
• Do not install the cable in parallel to the other lines, in particular not
devices with a high electromagnetic interference, such as frequency
converters.
