This product provides span powering voltage (negative only with respect to ground, –190 VDC
nominal, GFI protection < 5 mA) and meets all requirements of Bellcore GR-1089-CORE (Class A2),
and ANSI T1.418-2002. This product is NRTL Listed to the applicable UL standards.
The H4TU-C provides –190 VDC span powering voltage and will provide powering to the H4Rs
and the H4TU-R. The –190 VDC span powering voltage is provided on Loop 2.
