COMPLIANCE
This product is intended for installation in restricted access locations only and in
equipment with a Type “B” or “E” enclosure.
WARNING: Up to -200 VDC might be present on telecommunications wiring. Ensure
chassis ground is properly connected.
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), ANSI T1.418-2002. This product is NRTL Listed to the
applicable UL standards.
