RS-485 Connection to F7
Inverter
The F7 Inverter can also communicate over RS-485. The RS-485 connection
can be either one-to-one or one-to-N. Up to 15 F7 Inverter units can be con-
nected in a one-to-N system.
The figure below shows the connection between one PRT1-SCU11 and 1 to
15 F7 Inverter units. Refer to the F7 Inverter User Manuals for more informa-
tion on Wiring.

Initial Setup Procedure
After mounting the PRT1-SCU11, the following Initial Setup Procedure must
be applied to allow the Unit to start up properly and to be configured for oper-
ation.
• A unique PROFIBUS node address must be selected, before the unit’s
power supply is turned on, see section
2-4-1 Selecting a Node Address
.
• Select the required baud rate to be used on the RS-422A / RS-485 net-
work, using DIP-switches 1 and 2. Select the protocol to be used, i.e.
Memobus or one of the other protocols, using DIP-switch 3. Disable the
Auxiliary port, using DIP-switch 4.
• Select the required physical layer, either RS-422A or RS-485, using
switch number 1, directly over the RS-422A / RS-485 connector.
• Setup the PROFIBUS network, see section
2-5 Setting up a PROFIBUS
Network
, configure the PROFIBUS Master unit using the master configu-
ration tool on the Personal Computer, and download the configuration to
the master unit.
• Refer to the manuals of the connected devices, on how to set up the
devices.

1.
Make sure that the power supply is turned OFF before setting the node ad-
dress.
2.
Set the switch to the desired node address, using a small screwdriver, and
taking care not to damage the rotary switch. The default node address is
0. Make sure that the node address is unique on the PROFIBUS DP net-
work, i.e. there must be no other unit with the same node address.
3.
Turn ON the power supply of the Unit.
