Safety Precautions
To reduce the chance of accident, please read the safety precautions 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 operation.
When operating Vertiv products, you must strictly observe the safety rules in the industry, the general safety
points and special safety instructions specified in this book.
Electrical Safety
I. Hazardous voltage
Danger
Danger
Some components of the outdoor power system carry hazardous voltage in operation. Direct contact or indirect contact
through moist objects with these components will result in fatal injury.
Observe safety rules in the industry when installing theAC 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 in the cabinet, just turn off the power immediately. In moist environment,
precautions must be taken to keep moisture out of the power system.
Attach ‘Prohibit’warning label to the switches and buttons that are not permitted to operate during installation.
Danger
Danger
High voltage operation may cause a fire or 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.
Danger
Danger
To avoid electric shock hazard of outdoor environment and outdoor equipment, the non-professionals are prohibited to
operate or maintain the outdoor power system.
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
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
Note
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, wear ESD wrist strap 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
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 constant voltage DC power equipment, and short circuit will result in equipment
burning and endanger human safety.
VI. Reverse connection
Warning
Never connect reversely live line and neutral line of the AC input cables, or else the system will be damaged.
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 tight, please carefully select the operation space.
Never wear a watch, bracelet, bangle, ring, or other conductive objects during operation.
Use insulated tools.
In live operation, keep the arm, wrist and hand tense, so that when the tool in operation slips, the movement of
the human body and tool is reduced to a minimum.
Others
I. Sharp object
Warning
When moving equipment by hand, wear protective gloves to avoid injury by sharp object.

II. Cable connection
Warning
Notice
Note
Please verify the compliance of the cable and cable label with the actual installation prior to cable connection.
III. Binding the signal lines
Warning
Notice
Note
The signal lines should be bound separately from heavy current and high voltage lines, with binding interval of at least
150mm.

The FSU acquires power monitoring information through RS485 port, and uploads information of components such
as heat exchanger and air conditioner through internal RS485 port. The FSU universally processes and transmits the
information to user monitoring system through Ethernet remote communication port. The appearance and port
position of the FSU are shown in Figure 1-15.

Sensor Introduction
Micro switch
Each cabinet door can be configured with a micro switch. When the door is open, the system will generate a door
open alarm. The appearance of the micro switch is shown in Figure 1-16.

Temperature & humidity sensor
A temperature & humidity sensor can be configured to each cabinet for detecting the temperature and humidity of
internal cabinet, and providing temperature basis for the system running control. The appearance of the temperature
& humidity sensor is shown in Figure 1-17.
Figure 1-17 Appearance of temperature & humidity sensor
Smoke sensor
A smoke sensor can be selected for each cabinet. When an unexpected failure occurred in the system cabinet and
producing smoke whose concentration reaches the sensor setting, the system will generate a smoke alarm. The
appearance of the smoke sensor is shown in Figure 1-18.
Figure 1-18 Appearance of smoke sensor
Water-logging sensor
The system provides a water-logging sensor as an option, which can only be configured in the main cabinet. When
the cabinet water level reaches the submerged position of that sensor, an water-logging alarm will be generated. The
appearance of the water-logging sensor is shown in Figure 1-19.

Infrared sensor
The system provides an infrared sensor as an option, which can only be configured in the battery cabinet. The
appearance of the infrared sensor is shown in Figure 1-20.

1.2.5 Heating Unit (Optional)
The power system can be configured with a heating unit; its appearance is shown in Figure 1-21.
Figure 1-21 Appearance of heating unit
The heating unit consists of the Positive Temperature Coefficient (PTC) heater, fan, temperature relay, fuse and
installation cover. It uses a built-in fan to release the heat produced by the heater to the cabinet, while the heater
starts or stops automatically according to the cabinet temperature.
