Overall wiring diagram for BASE-E and extension
power unit (B)
Connecting the supply voltage – power unit 100 to 230 V AC
1. Route the power supply cable through the appropriate cable entry and into the
housing.
2. Connect the protective ground of the power unit to the threaded bolt specially
provided on the cable mounting rail.
3. We recommend you connect the protective ground or ground cable provided onsite to
the mounting bolt. For this purpose, pull the protective ground or the ground cable
through the cable entry and connect it to the threaded bolt on the cable mounting
rail.
4. Connect cable cores L and N to the plug-in terminals of the power unit as shown in
the wiring diagram.
Requirements for protective ground / ground cable
• Onsite fuse 10 A: wire cross-section min. 0.75 mm
2
(18 AWG)
• Onsite fuse 16 A: wire cross-section min. 1.5 mm
2
(14 AWG)
