Safety Notice
Figures 28 and 29 identify connectors for Safety Extra-Low Voltage (SELV)
and Telecommunications Network Voltage (TNV) circuits on the control unit's
main PCB. These terms are used in accordance with the definitions in Safety
Standard EN60 950.
The Installer must ensure that TNV terminals are connected only to other
circuits designated as TNV circuits (for example, the PTSN) and that SELV
terminals are connected only to other circuits designated as SELV circuits.
Strict adherence to the installation instructions will ensure that the equipment
continues to comply with the safety regulations to which it was approved.
