SAFETY INSTRUCTIONS
1.
For North America, input voltage (nominal 48Vdc, tolerance 36-60Vdc) must be applied by an isolated DC source complying with the
earthed SELV or TNV requirements of the UL1950, Third edition.
For other countries, input voltage (nominal 48Vdc, tolerance 36-72Vdc) must be supplied by an isolated DC source complying with the
earthed SELV or TNV requirements of the latest version of EN60950.
2.
DC input must be protected by a UL Listed fuse rated maximum T2A, 250V (slow-blow 2A , 250V fuse).
3.
When applicable, protection from excessive voltage on the output should be tested in end-use equipment.
4.
For output voltage exceeding 80Vrms, compliance with the ringing signal requirements should be tested in end-use equipment. When
the output voltage is set to less than 80Vrms, the ringing signal complies with M.2 requirements of IEC950.
