2.3.2 Power Supply Connector
To supply the frequency converter with power, connect the external DC power supply
to the "9 V / MAX. 1.1 A" DC input (labeled "9 V / MAX. 1.6 A" on R&S ZVA-Z500 con-
verters). For details, see
on page 15.
Always switch the instrument to standby state before removing the power supply.
Risk of instrument damage
The input voltage and current must not exceed the maximum values according to the
rear panel labeling or the data sheet.
Notice that the external DC power supply units of R&S ZVA-Z500 converters support
higher output powers. Always use the DC power supply delivered with your frequency
converter.
