5. Installation
5.1 Basic configuration
Before installing the FTC470XMB, an address must be assigned to it. The BMS bus and the
Modbus RTU must also be provided with an address.
1. At first, consult the person in charge of the electrical installation for the address assignment of
the protocol converter in the respective bus structures. Therefore, it is necessary to find out
whether the FTC470XMB can be operated as BMS Master (basic setting).
2. Set the appropriate BMS address (1 to 30; 1 = Master) by means of the DIP switch using binary
digits. Address 5 corresponds to the following switch positions, for example:
A4=0 A3=0 A2=1 A1=0 A0=1
Factory setting = 1
3. Set the appropriate Modbus RTU address (1 to 127) by means of the DIP switch ( to 7). For
details refer to the chapter 4.2.1 "DIP switch for Modbus RTU address assignment".
Information about addresses up to 30 can be found in the BMS binary table on page 17.
Factory setting = 3
4. Set the baud rate to (1200 to 57600 Bit/s). For details refer to chapter 4.2.2 "DIP for setting the
baud rate".
Factory setting = 9600 Bit/s
5. Set the parity bit (Parity) for data transmission (none/even/odd)
Factory setting = none
6. Set the termination switch R to the required position in order to activate or deactivate the
internal terminating resistor:
– If the FTC470XMB is located at the end of the
Modbus RTU
, set the switch R to "ON" posi-
tion (down position). The terminating resistor is activated.
– If the FTC470XMB is not located at the end of the
Modbus RTU
, set the switch R to up posi-
tion. the terminating resistor is deactivated.
5.2 Mounting and connection of the device
1. Mounting on support rail
Snap the clamping springs at the rear of the FTC470XMB into place in a way that a tight and
secure fit is ensured.
2. Connection to supply voltage U
S
:
Connect the terminals A1 and A2 to a supply voltage of U
S
= 85 to 275 V (AC/DC). Other supply
voltages are under consideration, please refer to the nameplate of the device. A 6 A fuse is rec-
ommended for the voltage supply. In case of connection to an IT system, all poles are to be
protected. In case of DC voltage supply, any connection polarity can be used.
Double assignment of addresses may lead to serious malfunctions in the BMS
or Modbus RTU networks concerned.
