Setting switch

DIP switches and a rotary switch are used for setting switches. DIP switches select communication
protocols, while a rotary switch sets a slave ID. When multiple units are connected, slave IDs are
used to identify the units. (A rotary switch is used only for functional slaves and CT extension slaves.
The slave for measurement master will have a fixed ID of 0. )

How to use setting switches

Be sure to use the switch when the power supply is turned OFF. The settings will be read
only when connected to a power supply and any change made during power distribution will
not be reflected. To make change, switch off the power first and change the settings. And
switch on the power again.
When selecting a switch, set it to the specified position securely by using a small flat-head
screwdriver.

to avoid duplicates.
