CAUTION Some functionalities of external measurement devices (for example, sensor purge in Vaisala probes) may increase the power
consumption of the devices momentarily. When powering external devices, please make sure that the additional power requirements do not exceed the capacity of the CAB100B power supply. If
in doubt, contact Vaisala for more information.
After connecting the power wires, reconnect power in the cabinet.
