Powering in Retrofit Installations
WMT700 is designed to operate with the same supply voltages as
WS425 and no connection changes are necessary. The power
consumption depends on the selected heating options. WMT700
with heated transducers can be used to replace similar WS425
models. When upgrading from WS425 to WMT700 with heated
transducers and arms, more capacity is required from the power
supply unit.
For information on power supply requirements of each WMT700
product type, see Table 27 on page 87.
NOTE
When WMT700 is in operation, the power consumption is higher than
with WS425. This can affect system performance in power-critical
applications such as solar-powered or battery-powered systems.
Use solar-power or battery backup only to secure operating voltage.
Ensure that the solar-powered system has a sufficient power reserve
available.
