Chapter 2 Installation Instruction
This chapter introduces installation and cable connection. Before installation, please read through safety regulations,
and then follow this instruction to carry out the installation step by step.
2.1 Safety Regulations
Certain components in this power system carry hazardous voltage and current. Always follow the instructions below:
1. Only the adequately trained personnel with satisfactory knowledge of the power system can carry out the
installation. The most recent revision of these safety rules and local safety rules in force shall be adhered to during
the installation.
2. All external circuits that are below 48V and connected to the power system must comply with the requirements of
SELV as defined in IEC 60950.
3. Make sure that the power (mains and battery) to the system is cut off before any operations can be carried out
within the system cabinet.
4. The power cabinets shall be kept locked and placed in a locked room. The key keeper should be the one
responsible for the power system.
5. The wiring of the power distribution cables should be arranged carefully so that the cables are kept away from the
maintenance personnel.
2.2 Preparation
Unpacking inspection
The equipment should be unpacked and inspected after it arrives at the installation site. The inspection shall be done
by representatives of both the user and Vertiv Tech Co., Ltd.
To inspect the equipment, you should open the packing case, take out the packing list and check against the packing
list that the equipment is correct and complete. Make sure that the equipment is delivered intact.
Cables
The cable should be selected in accordance with relevant industry standards.
It is recommended to use the RVVZ cables as AC cables. The cable should reach at least +70°C temperature
durability. Select the AC cable CSA according to Table 2-1.
Table 2-1 AC cable CSA selection
Connector Specifications AC cable CSA
AC input MCB 1 × 63A/4P, four H-tube cable terminals 10mm 2 ~ 35mm 2
AC input MCB 1 × 32A/4P, four H-tube cable terminals
6mm
2
~ 16mm
2
AC input MCB 1 × 100A/4P or 1 × 100A/2P, one or two H-tube cable terminals 16mm
2
~ 35mm
2
AC output terminals UK35/2P, two H-tube cable terminals 25mm 2 ~ 35mm 2
Note:
With cable length shorter than 30m, the CSA calculation should be based on the current density of 2.5A/mm 2 . The suggested
CSA value is not smaller than 15mm
2
The CSA of DC cable depends on the current flowing through the cable, the allowable voltage drop and load peak
current. The recommended load peak current is 1/2 to 2/3 of MCB or fuse capacity.
