SINUS Penta
Keypad Remoting Kit for RS485
GENERAL FEATURES
The keypad remoting kit is used to connect a standard SINUS PENTA keypad to one or multiple inverters
manufactured by Elettronica Santerno via an RS485 link using protocol MODBUS RTU. The keypad can then
communicate with one device at a time and will become the network master, thus avoiding communicating
with any other master devices (e.g. PLCs).
The keypad automatically detects which device it is connected to. If multiple devices are connected, you can
select the device to be used from a selection list.
The devices connected to the same network must have different addresses,
NOTE
otherwise no communication is possible.

Inverter-side connection: use 9-pole, male D connector. To gain access to the D connector, just remove the
cover on top of the inverter (size S05..S15), or remove the cover from the inverter bottom, located next to the
control terminals (size ≥ S20). For more details on D connector, see Sunway T’s Installation Manual. If
multiple inverters are connected to the same network, use a connector having the same features as the
connector installed on the inverter.
The connector pins are detailed in the table below.

3 CONNECTION
Remove voltage from the inverter. Then proceed as follows:
Disconnect the keypad installed on the inverter (if any)
Please refer to the Installation Manual of the inverter being used.
Connect the cable to the interface converter and the keypad
Connect connector DB9 to the inverter or to network RS485. The inverter side with telephone connector RJ45
must be already connected to the keypad.
Check that communication is correct
Turn on one of the inverters connected to the network. The keypad shows POWER ON. To scan the inverters
connected to the network, set the device address on the keypad to 0 (please refer to the Programming Manual
of the inverter being used). The list of the connected devices appears on the keypad display. Select the device
to be used to start communicating with the keypad, using all functionalities offered by the connected device.
Please refer to the Users Manual of the device being used for the operation of the keypad connected to the
device.
