Cables are used for inter-cabinet connections (1500, 3000 and 6000 A systems) or connections to the overhead busbars (6000 A system) for ease of expansion on live systems. In a 1500, 3000 or 4000 A systems, the power system battery return (BR) busbar is mounted externally from the cab- inet to facilitate the connections of the battery return cables. In a 6000 A system, a separate BR busbar dedicated to the battery returns for the loads is mounted externally from the overhead busbar duct to facilitate the connections of the load battery return cables.

The Helios DC System 4000/48 provides a variety of monitoring and alarm features, such as high/ low float and high/low voltage alarm, high voltage shutdown, fuse and breaker alarm and rectifier failure alarms.

The Helios DC System 4000/48 uses Helios Rectifiers 200I/48, Helios Rectifiers 200E/48 or Helios Rectifiers 100/48 connected in parallel as building blocks to reach the maximum capacities. The Helios Rectifiers 200I/48 operate from a 380 V to 415 V three phase, 50 or 60 Hz AC source. The Helios Rectifiers 200I/48 operate from a 480 V three phase, 50 or 60 Hz AC source. The Helios Rectifiers 100/operate from a 208 V to 240 V single phase, 50 or 60 Hz AC source.

The 1200 A rectifier cabinet accepts up to six Helios Rectifiers 200I/48 or 200E/48, while the 1000 A rectifier cabinet accepts up to 10 Helios Rectifiers 100/48.

The control and distribution cabinet and the auxiliary distribution cabinets are available with distribution busbar risers of 2000 A or 3000 A capacity.

The cabinets are seismic qualified to zone 4 (Bellcore) when anchored to a concrete floor whose compressive strength is at least 2.11 kg/mm2 (3000 psi) and when equipped with a seismic kit. The cabinets are seismic qualified to zone 2 without the seismic kit.

The cabinets are equipped with a ventilated, lockable door, a ventilated top cover and two rear ventilated panels.

In many applications, such as with DMS, a consistent single-point ground (SPG) topology must be maintained for all associated equipment. The Helios DC System 4000/48 complies with this requirements for single-point grounding (the isolation kit is required).

2.2Applications

The Helios DC System 4000/48 is designed to operate with DMS systems or any other telecommu- nication systems whose input is nominal -48 V DC and whose current requirements do not exceed 6000 A capacity.
