When VA of the main input is closed, the green LED of the main contact
group position of the main input -ON is on.
When the VA of the standby input is closed, the green LED of the position of
the main contact group of the standby input - ON is on.
In AVR-2 LITE, there is no logic of LED signaling in case of overcurrent
tripping.
Troubleshooting and remedies are shown in table 5.
The overall and mounting dimensions of the AVR are shown in figure 8 and in
the table 5.
The overall and mounting dimensions of the AVR are shown in figure 8 and
in the table 5.
Circuit diagram of primary, reserve and control circuits of AVR are shown
in figures 9 and 10.
ATTENTION
For correct operation of AVR-1 STANDARD, the connection diagram
should correspond to the diagram shown in figure 9.
Completeness of set
Delivery set of AVR is listed in table 6.
Safety measures
Mounting and commissioning of the AVR should be carried out only by
qualified electrical personnel.
The operation of the automatic transfer switch should be carried out in
accordance with the current requirements of the rules for electrical safety, as well
as other reference documentation regulating the operation, adjustment and
repair of electrical equipment.
Installation and operation rules
AVR is installed on a metal panel with a thickness of at least 1,5 mm or on an
insulating panel with a thickness of at least 6 mm and fixed with screws
AVR mounting is carried out with flexible, rigid copper or aluminum
conductors with a cross-section according to the connecting capacity of the
terminals specified in tables 1 and 3.
It is recommended to check the AVR performance at least once every three
months.
