Vaisala Indigo500 Series - Relay output terminals and lead-through; Analog output terminals and lead-through

1. Strip 55 mm (2.17 in) of the cable to expose the wires.
2. Cut o 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).
