9.5.5 Connecting optional components
Installing cable strain relief
Secure the cables with a strain relief clamp. Clearance to controller: 200 mm.
Connecting function ground
Connect ground to positive battery terminal '1+' Bat+ Fig. 1 (observe section 9.2.7).
Installing lightning protection
Install suitable lightning protection.
Connecting relay outputs 1 and 2
1. Connect external components to the relay outputs ‘AUX 1‘ und ‘AUX 2‘.
2. Configure the relay outputs as per section 14.
Connecting the external temperature sensor Steca PA TS-S
1. Install the temperature sensor Steca PA TS-S near to the battery.
2. Connect the sensor cable to contacts 7 (‘EXT.’) and 8 (‘GND’) (any polarity).
3. Set the temperature sensor under ‘Main menu’
‘Battery settings’ ‘Temperature sensor’
to ‘external’.
StecaLink bus: connecting master and slave devices
1. Set the addresses of suitable slave devices (observe section 9.2.1).
2. Connect the slave devices to the StecaLink bus.
3. Connect the StecaLink bus to the ‘MASTER’ RJ45 socket.
4. Connect the slave bus to the ‘SLAVE IN’ and ‘SLAVE OUT’ RJ45 sockets.
5. Terminate the last slave device according to the manufacturer's instructions.
Controller: plug optionally available termination plug into the open socket 'SLAVE IN' / 'SLAVE
OUT' on the last controller.
Connecting the open UART interface
Connect external devices to the open UART interface (observe in section 9.2.6).
CAUTION!
Danger of destruction of the relays. Observe the technical data of the relays (section 18)!
