Connecting to the power supply
The connection is made via one (or two) 3-pin connector(s) on the terminal block for the power
supply.
NOTICE
Damage to the device due to incorrectly wiring the terminal blocks
With devices with a supply voltage of 100 to 240 VAC and 60 to 250 VDC, the terminal blocks
for the power supply and signaling contact are plugged in and screwed down in the device.
Both terminal blocks have three pins but coding prevents the two terminal blocks being
confused.
Make sure that the cables of the power supply and the cables for the signaling contact are
connected to the correct terminal block.

To wire up the power connector, use a copper cable of category 18-8 AWG or cable with a
cross-section of 0.75 to 6 mm².
DC voltage is connected at the following terminals:
● Plus to "L"
● M to "N"
Secure the firm seat of connectors and the terminal block by tightening the screws (does not
apply to X‑300EEC).
