Precautions
When connecting cables to both the power terminal and the
USBportontheVZ20X,makesuretosupplypowerfrom
the power terminal before connecting the USB cable.
Power is supplied from both the power terminal and the USB
cable.Forthisreason,makesuretodisconnecttheUSB
cablebeforeturningOFFtheVZ20X.
Forapermanentinstallation,supplypowerfromthepower
terminal. Use the USB power supply for temporary
applications.
Whenperformingtransitionwiring,takecaretoprevent
short-circuits due to exposed sections of conductive parts
(including twin ferrule terminals) and loose strands in twisted
wire.
