Safety Precautions

To reduce the chance of accident, please read the safety precautions very carefully before operation. The"Caution, Note, Warning, Danger" in this book and on the product 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 receive strict training and master the correct operations and all the safety points before operation.

When operating Emerson products, the operation personnel must observe the safety rules in the industry, the

general safety points and special safety instructions specified in this book.

If you purchase an outdoor power supply without SPD, you should install an SPD at the front-end of AC input,

otherwise, the power supply system will generate over-voltage.

Electrical Safety

I. Hazardous vo ltage

Danger

Some components of the outdoor cabinet 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 the power supply 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 and rings.

When you spot the cabinet with water or moisture, turn off the power immediately. In moist environment,precautions must be taken to keep moisture out of the power supply 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 compliancewith the local rules and regulations. Only those who are licensed to operate high voltage and AC power can perform high

voltage operations.

Danger

To avoid electric shock hazard for outdoor environment and outdoor equipment, the non-professionals are prohibited tooperate or maintain the outdoor power supply system.

II. Tools

Warning

In high voltage and AC operation, specialized tools must be used.


3/34

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

Note

The static electricity generated by the human body will damage the static sensitive elements on PCBs, such as large-scaleICs. 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 ci rcuit

Danger

During operation, never short the positive and negative poles of the DC distribution unit of the outdoor cabinet system, orthe non-earth pole of the outdoor cabinet system and the earth. The power supply system is a constant-voltage DC power

device, short circuit will result in equipment burning and endanger human safety.

VI. Reverse connection

Warning

Never reverse-connect the AC input live line and neutral line, or else the system will be damaged.

Check 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.

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.

4.2.3 Replacing Door Status Sensor

There is a door status sensor installed in the cabinet for detecting the close or open status of the cabinet door. The

alarm will be eliminated only when the cabinet door is closed.

The door status sensor requires no particular maintenance; just replace it when it is damaged. If the door is closed,

while the door status sensor alarm occurs, the sensor must have been damaged. The position of the sensor is shownin Figure 4-7.

Remove the sensor top cover and then the two screws. Replace the old sensor with a new one and finally fix the

sensor and the signal cables with the screws.

Step 2: Disconnect J15 terminal (shown in Figure 4-9), and then disconnect the rest connection terminals on the

ECCU.

Step 3: Loosen the fixing screws on the ECCU. Replace the ECCU with a new one.

Step 4: Reverse connection sequence in step 2 to connect terminals, so as to check that the LED_FAULT (shown in

Figure 4-9) indicator show correctly. Under normal instance, the LED_FAULT indicator is power-off.

Step 5: Place the DIP switch to the correct position according to Table 4-3and Table 4-4.

Step 6: Press the SW1 self-test button (shown in Figure 4-9) to ensure that the fan can start normally.

Step 7: Replace the cover of the ECCU.

4.3.2 Replacing Fans

The heat exchanger of the outdoor cabinet is mainly composed of four centrifugal fans and a heat-exchanging core.

If the fan is faulty, follow the following procedures to replace the fan.

Step 1: Make sure that the fan-control terminals (J1, J2, J3 and J4 are hot pluggable) on the ECCU are inserted firmly.

The fan-control terminals are shown in Figure 4-9.

Step 2: Place the DIP switch to the correct position according to Table 4-3and Table 4-4.

Step 3: Press the SW1 self-test button (shown in Figure 4-3). If the fans do not work, make sure that the fan cablesare perfect.

Step 4: Disconnect the fan power terminals on the right side of the cabinet. Use a multimeter to measure the voltage

between the positive power terminal and the negative power terminal. Check if the voltage is close to the DC output

voltage (54.0V).

If the fan power voltage is normal, the fans are damaged. Carry out the next step.

Step 5: Loosen the fixing screws to remove cover of heat exchanger (shown in Figure 4-11), and then you can see

the fans. Loosen the fixing screws of the fans to replace the fans.

Step 6: Reconnect the fan power terminals, and press SW101 self-test button (shown in Figure 4-9) to ensure that the

fan can startup normally.

Step 7: Replace the heat exchanger cover.
