Display test at power up
When connecting the auxiliary voltage to the relay:
1. The backlight will be turned on after the relay has performed the internal
power-up tests and entered into the protection mode.
2. The display will be tested by inverting it for approximately three seconds, see
Fig. 3.1.2.1.-1. In case a restart inhibit indication is displayed, the display test
will not be run at power up.
