3.3.2.1 Preparing AC (mains) power cable
Only factory installed AC (mains) cables have been safety type
tested and assembly tested with the product. Modifying or replacing the factory
installed AC (mains) cable will void UL/SGS listing.
CAUTION!
• Cable stripping tool
Prepare the AC (mains) power cable for connection to the power supply input terminal:
Figure 14 Example of stripped AC (mains)
power cable
Number in figure Wire Min. … max. wire cross-section
1 Line wire
0.5 … 2.5 mm
2
(20 … 14 AWG)
2 Neutral wire
3 Grounding wire
1. Strip 55 mm (2.17 in) of the cable to expose the wires.
2. Cut off 10 mm (0.39 in) of the line and neutral wires. Leave the grounding wire 55 mm
(2.17 in) long.
Make sure that the grounding wire is longer than the line and
neutral wires. Under mechanical stress, the grounding wire must be the last
to disconnect from the protective ground terminal.
CAUTION!
3. Strip the ends of the individual wires to expose the conductors for a length of 8 mm
(0.32 in).
3.3.3 Relay output terminals and lead-through
Before connecting wires or cables, make sure that the transmitter is powered off.
