1 The capacity of the backup battery degrades in cold temperatures.
2 In PSU501, solar panel or other external DC power supply is connected to DC in. EGW501 of Connected Compact Station BWS500 is connected to DC out.
3 DC power supply must have reinforced insulation between AC (mains) and output.
4 The actual output voltage equals the DC input voltage (max. 32 V).
5 Vaisala recommends, for example, YUASA NP7‑12.
