Purpose
The SZR-277 single-phase controller of backup switching is used to
control the voltage of the single-phase power supply network and
to switch the receiving line to the power supply from the generator
in case of incorrect parameters of the main power supply line.
Functioning
If the mains voltage is within the specified range, the contact
between terminals 2-7 is closed and the mains power is
transferred to the receiving line. If the permissible voltage
parameters are exceeded, the contact 2-7 is opened and the
supply line is disconnected from reception. When the main line is
disconnected, the generator starts up and then, by closing the 3-9
contact, the power supply from the generator is transferred to the
receiving line.If the power supply on the main line is restored and is
within the specified range for 10 seconds,
the contact 3-9

Keep the product in a warm room for at least 2 hours
before connecting it to the mains power supply (for
storage or transport at low temperatures) to prevent
damage caused by condensation.
