Pin
By default upon delivery, terminal strip X18 is supplied with a jumper inserted between
pins 1 and 2.
If no switch is connected to X18, the jumper can remain inserted. The power level of the
power-level terminal is enabled because the 24 V segment voltage is directly available.
If an external switch is connected between pins 1 and 2 on terminal strip X18, the power
level of the power-level terminal is enabled when the switch is closed.
