☐ Cable type: copper wire, tin-plated
☐ Wire cross-section: 0.25 mm²
Danger to life due to electric shock
• Do not disconnect or connect the AC field plug under load.
• Only assemble the AC field plug in a dry environment.
• Observe the operating temperature range of − 40°C to +85°C.
Always assemble the AC field plug as follows in the prescribed order:
Assembling the Cable
1. Shorten the cable to the desired length using cable shears.
2. Dismantle the cable by 42 mm using the stripping knife. Take care not to damage the individual
insulated conductors.
• The grounding conductor must be 42 mm long. The grounding conductor must be
approximately 7 mm longer than L and N.
• L and N must each be 35 mm long.
3. Using the insulation stripping tool, strip the insulation of the three individual conductors each by
10 mm (tolerance: ± 1 mm). Take care not to damage the individual stranded wires.
☑ The cable is assembled.
4. Push one bootlace ferrule onto each stripped insulated conductor up to the stop.
5. Crimp the bootlace ferrule tightly using a crimping tool.
6. Ensure that a crimping length of max. 2.4 mm is maintained.
Premounting the AC Field Plug
1. Slide the screw connection over the cable with the bootlace ferrules. Ensure that the thread of
the screw connection is facing the bootlace ferrule.
2. Use your fingers to push the seal as far as possible into the plug enclosure.
3. Lead the plug enclosure with the seal over the cable. The thread must be facing the thread of
the screw connection.
