Relay 2 has just one N.O. contact. The relay can be used to forward messages to external units. This
relay can also be used to implement alarm (warning) and fault alarm functions. Other functions will
follow in the future and you may send us suggestions or requests for such functions. The contact
rating is 230V AC or 30V DC, max. 5 A.
The connector pin assignments are as follows: (Pin 1 is on the left)
X5, pin 4 Relay 2, two-way contact COM
X5, pin 5 Relay 2, N.O. contact

Contacts illustrated deenergised
Possible settings for parameters 46 and 47:
Value = 0 Relay 1 or 2 always deenergised. The COM and N.O. contacts are always open. The
COM and N.C. contacts are always closed.
Value = 1 Relay 1 or 2 is energised as long as the inverter is suffering from a fault and is not
operating. In this case, the COM and N.O. contacts are closed and the COM and N.C.
contacts open.
Value = 2 Relay 1 or 2 is energised as long as the inverter is not suffering from a fault and is
operating. In this case, the COM and N.O. contacts are closed and the COM and N.C.
contacts open.
Value = 3 Relay 1 or 2 is energised as long as the inverter displays an alarm. In this case, the
COM and N.O. contacts are closed and the COM and N.C. contacts open.
Value = 4 Relay 1 or 2 is energised as long as the inverter is not displaying an alarm. In this
case, the COM and N.O. contacts are closed and the COM and N.C. contacts open.
Value = 5 Relay 1 or 2 is energised as long as the inverter displays an alarm or a fault. In this
case, the COM and N.O. contacts are closed and the COM and N.C. contacts open.
Value = 6 Relay 1 or 2 is energised as long as the inverter is not displaying an alarm or a fault.
In this case, the COM and N.O. contacts are closed and the COM and N.C. contacts
open.
Value = 7 Relay 1 or 2 is energised if the inverter temperature (parameter 16) is higher than
50°C. If the inverter temperature falls below 48°C, the relay in question is
deenergised.
Value = 8 Relay 1 or 2 is energised if the inverter temperature (parameter 16) is higher than
55°C. If the inverter temperature falls below 53°C, the relay in question is deenergised.
Value = 9 Relay 1 or 2 is energised if the inverter temperature (parameter 16) is higher than
60°C. If the inverter temperature falls below 58°C, the relay in question is deenergised.
