Hipulse - Single Phase ‘1+N’ UPS System

130 kVA - 110V

CHAPTER 3

Installation (Electrical)

The UPS requires both “Power” and “Control” cabling once it has been mechanically installed. All Control cables, whether screened or not, should be run separate from the Power cables in metal conduits or metal ducts which are electrically bonded to the metalwork of the cabinets to which they are connected.

3.1Power Cabling

WARNING

Before cabling-up the UPS, ensure that you are aware of the location and operation of the external isolators that connect the UPS input/ bypass supply to the mains distribution panel.

Check that these supplies are electrically isolated, and post any necessary warning signs to prevent their inadvertent operation.

For cable entry, refer to section 2.3.5

3.1.1System Configuration

The power cables of the system must be size with respect to the following description:

Module input cables

The module input cables must be sized for the maximum input current, including the maximum battery recharge current, given in the table 3-1, with respect to the module rating and the input a.c. voltage.

Module Bypass and Output cables

The Bypass and Output cables must be sized for the nominal output current, given in the table 3.1, with respect to the module rating and the output a.c. voltage.

Battery cables

Each UPS module has its own battery, which is connected using two cables, one positive and one negative. The battery cables must be sized for the battery discharge current at the end-of-discharge voltage, as given in the table 3-1, with respect to the module rating.
