1 Installation
The NetSure HVT F02 CK1 power system (power system for short) is designed by Vertiv Tech Co., Ltd. It is a new generation of
power system with high reliability and performance. It is mainly used in IDC equipment room of the large data center to provide
400V DC input power for the new generation of servers.
This chapter introduces installation and connection of the power system. Before installation, please read through safety
regulations, and then follow this instruction to carry out the installation and connection step and step.
1.1 Installation Preparation
1.1.1 Tools Preparation
See 4.1.2 Maintenance Tools and Equipment for the specifications of the tools. The tools must be well insulated and antistatic
handled prior to use.
1.1.2 Cables and Materials Preparation
Preparing cables
The cable design should meet relevant industry standards.
It is recommended to use the RVVZ cables as AC cables, and voltage level is 450/750V or higher. The cable should reach at least
+70°C temperature durability. With cable length shorter than 30 meters, the Cross-Sectional Area (CSA) calculation should be
based on the current density of 2.5A/mm
2
.
The sectional area of the DC load cables and battery cables should be computed with the following formula:
A=
Σ
I × L/K
△
U
In this formula: A is the sectional area of the lead (mm
2
),
Σ
I is the total current (A) passing through the lead, L is the length (m) of
the lead loop,
△
U is the permitted voltage drop in the lead, while K is the conductivity factor. K
copper
=57. For the sake of
distribution safety, the voltage drop on the cables should be compliant with corresponding rules.
NOTE! AC cables of rectifier cabinet have been configured into the cabinet delivery accessories. If AC distribution
cabinet is far from the rectifier cabinet at site, and the accessory cables cannot meet the requirements, then select the
appropriate cables according to actual situation.
The AC cable CSA of rectifier cabinet is listed in Table 1.1.

. The suggested CSA value is not less
than 70mm
