Grounding cable requirements:
• Core cross-section: 0.5 mm² to 1.5 mm² (16 AWG to 20 AWG)
• Number of insulated conductors: 1
• Maximum cable length: 3 m (9.8 ft)
Procedure:
1. Mount the power supply unit (see the manufacturer manual).
2. Connect the connection cable to the power supply unit (see the manufacturer manual). Make
a note of the insulated conductor colors and trim the unused insulated conductors back to the
cable sheath.
3. Connect the connection cable to the supplied 3-pole
terminal block. To do this, release the screws of the
required terminal points using a suitable tool, plug
the wires into the terminal points and tighten the
screws of the terminal points hand-tight. Observe the
pin assignment.
