Safety Precautions

To reduce the chance of accident, please read the safety precautions very carefully before operation. The
"Caution, Notice, Warning, Danger" in this book do not represent all the safety points to be observed, and are
only supplement to various safety points. Therefore, the installation and operation personnel must be strictly
trained and master the correct operations and all the safety points before actual operation.

When operating Vertiv products, the safety rules in the industry, the general safety points and special safety
instructions specified in this book must be strictly observed.

Electrical Safety

I. Hazardous voltage

Danger

Some components of the power system carry hazardous voltage in operation. Direct contact or indirect contact through
moist objects with these components will result in fatal injury.

Safety rules in the industry must be observed when installing the power system. The installation personnel must
be licensed to operate high voltage and AC power.

In operation, the installation personnel are not allowed to wear conductive objects such as watches, bracelets,
bangles, rings.

When water or moisture is found on the Subrack, turn off the power immediately. In moist environment,
precautions must be taken to keep moisture out of the power system.

"Prohibit" warning label must be attached to the switches and buttons that are not permitted to operate during
installation.

Danger

High voltage operation may cause fire and electric shock. The connection and wiring of AC cables must be in compliance
with the local rules and regulations. Only those who are licensed to operate high voltage and AC power can perform high
voltage operations.

II. Tools

Warning

In high voltage and AC operation, special tools must be used. No common or self-carried tools should be used.

III. Thunderstorm

Danger

Never operate on high voltage, AC, iron tower or mast in the thunderstorm.

In thunderstorms, a strong electromagnetic field will be generated in the air. Therefore the equipment should be
well earthed in time to avoid damage by lightning strikes.

IV. ESD

Notice

The static electricity generated by the human body will damage the static sensitive elements on PCBs, such as large-scale
ICs. Before touching any plug-in board, PCB or IC chip, ESD wrist strap must be worn to prevent body static from
damaging the sensitive components. The other end of the ESD wrist strap must be well earthed.

V. Short circuit

Danger

During operation, never short the positive and negative poles of the DC distribution unit of the system or the non-grounding
pole and the earth. The power system is a constant voltage DC power equipment, short circuit will result in equipment
burning and endanger human safety.

Check carefully the polarity of the cable and connection terminal when performing DC live operations.
As the operation space in the DC distribution unit is very tight, please carefully select the operation space.
Never wear a watch, bracelet, bangle, ring, or other conductive objects during operation.
Insulated tools must be used.
In live operation, keep the arm muscle tense, so that when tool connection is loosened, the free movement of

the human body and tool is reduced to a minimum.

VI. Dangerous energy

Warning

More than 240VA system capacity, keep away from hazardous energy and avoid bridge connection.

Battery

Danger

Before any operation on battery, read carefully the safety precautions for battery transportation and the correct battery
connection method.

Non-standard operation on the battery will cause danger. In operation, precautions should be taken to prevent
battery short circuit and overflow of electrolyte. The overflow of electrolyte will erode the metal objects and PCBs,
thus causing equipment damage and short circuit of PCBs.

Before any operation on battery, pay attention to the following points:
Remove the watch, bracelet, bangle, ring, and other metal objects on the wrist.
Use special insulated tools.
Use eye protection device, and take preventive measures.
Wear rubber gloves and apron to guard against electrolyte overflow.
In battery transportation, the electrode of the battery should always be kept facing upward. Never put the battery

upside down or slanted.

Battery installation requires reliable grounding. And battery is connected before accessing the battery protection
device.

Others

I. Sharp object

Warning

When moving equipment by hand, protective gloves should be worn to avoid injury by sharp object.

II. Cable connection

Notice

Please verify the compliance of the cable and cable label with the actual installation prior to cable connection.

III. Binding the signal lines

Notice

The signal lines should be bound separately from heavy current and high voltage lines, with binding interval of at least
150mm.

Chapter 2 Installation Instruction

2.1 Safety Regulation

Certain components in this power system carry hazardous voltage and current. Always following 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. With cable length shorter than 30 meters, the Cross-Sectional Area (CSA) calculation should be based on
the current density of 3.5A/mm2. The suggested CSA value is no less than the Table 2-1.

The CSA of DC cable depends on the current flowing through the cable and the allowable voltage drop. To select the
battery cable CSA, see Table 2-2,select the DC load cable CSA according to the 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.

Note: The specs are applicable at ambient temperature of 25°C. If the temperature is higher than this, the CSA of the cable should
be increased.

To prevent the air switching capacity is too large, the load doesn't work when overload. Recommended the capacity
of the air switching is up to 1.5~2 times of the load peak.

The CSA of the system grounding cables should be consistent with the largest power distribution cables. The CSA
value is no less than 25mm2.
