NetSure 211 C23 Embedded Power Supply System User Manual

Chapter 2 Installation Instruction

This chapter introduces installation and cable connection. Before installation, please read through safety regulations,

and then follow the instructions provided in this chapter to carry out the installation and cable connection.

2.1 Safety Regulations

Certain components in this 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 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 Emerson Network Power 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 Cross-Sectional Area (CSA) according to Table 2-1.

~ 4mm

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.

Select the battery cable CSA according to Table 2-2. Select the load cable CSA according to Table 2-3.

Note:

1. The specs are applicable at ambient temperature of 25°C.

2. The battery cable should reach at least +90°C heat durability. It is recommended to use double-insulated copper-core

flame-retardant cable as battery cable
