The devices to be connected to the output must comply with the following requirements:
Direct current: Maximum Reverse Voltage: 10 V, Maximum Current: 8 mA.
Auxiliary +5 V output a07
Included on connector a07 is an auxiliary 5 V output. The maximum allowed absorption by this
auxiliary supply voltage is 100 mA.
Configurable relay a05
The inverter has a multi-function relay a05, whose switching can be congured, for example, to
activate a visual and/or audible alarm or be utilized by another control such as a building control
system. The relay can be wired by the user as either normally open contact – N/O – or normally
closed contact – N/C.
The devices to be connected to the relay can be of different types (light, sound, etc.) but must
comply with the following requirements:
Alternating current: Maximum Voltage: 240 Vac, OV Category II
Maximum Current: 1 A
Direct current: Maximum Voltage: 30 Vdc, Maximum Current: 0.8 A
Cable requirements: Conductor size: from 24 AWG - 16 AWG
This contact can be used in four different operating modes which are
set via the programming menu of the inverter display in Operations,
section 4, of this manual. The four operating modes and switch
congurations are described below.
Production - the relay switches whenever a connection to the grid
occurs.
If the N/O (or N/C) contact is chosen, the contact will stay open (or
closed) until the inverter is connected to the grid. Once the inverter
connects to the grid and starts to export power, the relay switches
state and closes (or opens).
When the inverter disconnects from the grid, the relay contact
returns to its position of rest, namely open (or closed).
Alarm - the relay switches whenever there is an alarm (Error) on
the inverter.
No switching occurs when there is a Warning.
If the N/O (or N/C) contact is chosen, the contact will stay open (or
closed) until the inverter reports an error; once the inverter reports
an error, the relay switches state and closes (or opens).
The contact remains switched from its rest condition until normal operation is restored.
