6.2.2 Commissioning the EMP
Refer to the section Contextual help>>>Environment>>>Commissioning/Status .
6.2.3 Enabling temperature compensated battery charging in the UPS
To enable the temperature compensated battery charging, refer to the UPS user manual.
Address must be defined before EMP power-up; otherwise, the changes will not be applied.
Do not set Modbus address to 0; otherwise, the EMP will not be detected.
Define a unique address for all the EMPs in the daisy-chain.
Set the RS485 termination (TER) to 1 on the last EMP of the daisy chain. On other EMPs this should be set to 0.
The temperature compensated battery charging feature needs to be enabled in the UPS.
