EM-TRF-USV Extension module for 230 V AC uninterruptible power supply (UPS)
Note:
This is the order code for retrofitting the expansion module into a VAV terminal unit with EASYLAB or TROX UNIVERSAL control component or a TROX adapter module TAM. When retrofitting, the EM-TRF-USV emergency power accumulator must be ordered in addition to the EM-TRF-USV-AKKU transformer module with emergency power function.
As a rule, the expansion module is ordered for the first time when the VAV terminal unit is ordered via the order code of the basic unit under the section Expansion modules with the order code U set. In this case, the emergency power accumulator is included in the scope of delivery
Important note
If the EM-TRF-USV extension module is installed, the TCU3 controller board must not be supplied with 24V.
Commissioning with factory preparation
When ordering the EASYLAB or TROX UNIVERSAL controller with EM-TRF-USV extension module, the module is installed at the factory, the battery is connected and ready for operation. The UPS performance in the event of a power failure (default = maintain regular operation) can be adjusted with the EasyConnect configuration software. An initial charge of approx. 24 h is required for full emergency power functionality.
