            Step 6: Remove the PEV

4.4.1.2 Removing the Cabinet Base Baffle

Use a Phillips screwdriver to remove the four screws that secure the base baffles on the front and back of the cabinet , and put the screws and baffles aside for temporary storage

4.4.1.3 Removing the Cabinet Pallet

Use a Phillips screwdriver to remove the four screws that secure the base baffles on the front and back of the cabinet , and put the screws and baffles aside for temporary storage

4.4.1.4 Remove the Protective Plate

Please open all cabinet doors first, use an M4 cross screwdriver, remove the screws, hold the protection plate handle to remove all cable protection plates, and then put the screws and protection plates aside for temporary storage .

4.4.1.5 Remove the Cabinet Base Cable Guard

Loosen the eight hand screws at the bottom of the cabinet but do not remove them. Push the cable guard to the outside of the cabinet until it is blocked by the screws and cannot be pushed forward.

4.4.1.6 Cutting Grommet

Use a utility knife, needle-nosed pliers or other tools to cut the wire guard ring at the bottom of the cabinet along the wire guard ring pattern.

4.4.2 Cabinet Installation

4.4.2.1 Use a Forklift Or Crane To Place The Cabinet On The Cement Platform.

Forklift installation requirements:

• Choose a forklift that can meet the cabinet installation requirements based on the cabinet's basic parameters;
• Before installation, choose the appropriate installation position according to the pallet prompts to avoid the cabinet tipping over during installation;
• Before installation, the forklift route should be cleared and the forklift should be stable when moving to avoid excessive shaking that may cause the cabinet to topple over;
• Align the mounting holes at the bottom of the cabinet with the reserved mounting bolts on the base and lower it smoothly.

Crane installation requirements:

• Select a crane that can meet the cabinet hoisting requirements based on the cabinet's basic parameters and the actual space on site;
• Before lifting, check whether the lifting ring on the top of the cabinet is installed tightly;
• The crane sling or bandage should be tied firmly and not fall off, and the lifting angle of the sling or bandage should be ≤60°;
• When tying the slings or bandages, the center of gravity of the cabinet should be considered to ensure that the cabinet is stable after being lifted;
• Before hoisting, the path of the lifting arm should be cleared, and the hoisting should be stable to avoid excessive shaking that may cause the cabinet to topple over;
• Align the mounting holes at the bottom of the cabinet with the reserved mounting bolts on the base and lower it smoothly. Requirements for vertically installing the cabinet on a cement base:
• Push the cable guard plate close to the outside of the cabinet until it is blocked by the screws and cannot be moved;
• After the cables are stripped, the positive and negative cables are inserted vertically into the cabinet from the opening at the bottom of the cabinet in the front-to-back direction;
• After connecting the cables, push the cover plate from the front and back sides of the cabinet close to the cables, and then tighten the thumb screws .
• Cables need to be divided before entering the cabinet, and the length needs to be reserved according to the base size and the wiring position in the cabinet. When hoisting or plugging in, try to keep the cables vertical to ensure that the cables can enter the cabinet smoothly when the cabinet is slowly lowered.

4.4.2.2 Cabinet Fixing

Use a forklift to lift the cabinet 100mm above the base and slowly lower it. After at least two people in front and behind the cabinet confirm that the cabinet base fixing holes are aligned with the base-embedded bolts, the forklift completely lowers the cabinet. At the same time, check the placement of the cabinet around it. If there is no abnormality, place the four M12 nuts and washers of the fixing bolts in sequence, use a socket wrench to fix the nuts, and then reset the base baffle.

                                    1 Cabinet | 2 Embedded bolts | 3 Base

4.4.3 Cabinet Grounding

After the cabinet is fixed, use M8 screws to fix the grounding flat steel to the grounding base at the right rear of the cabinet.

4.4.4.1 Terminal Power Supply And Communication Wiring

The host provides system AC power (AC230V), CAN communication, and Ethernet for the terminal. The wiring locations are shown in the figure below:

4.5 Power up

———————————————————————————————————————

Danger :

Please use special protective equipment and special insulating tools to avoid electric shock or short-circuit.

———————————————————————————————————————

Notice :

• The equipment commissioning process involves a lot of technical content, and the commissioning personnel must receive corresponding technical training. Follow the commissioning instructions.
• The commissioning process involves live work. When operating, please stand on dry insulating materials and do not wear metal objects such as watches and necklaces. Use insulated tools during commissioning.
• During operation, avoid human body contact with two charged objects with different electrical potentials.
• During the commissioning process, before any “closing operation”, be sure to check whether the status of the relevant units or components meets the requirements. The voltage at the front end of the circuit breaker needs to be measured to ensure that the input voltage is within the rated range.
• During the operation, if other people are not allowed to operate, a prohibition sign should be hung on the power distribution equipment: "Do not close the switch, someone is operating."
• During the commissioning process, you should observe while commissioning. If you find any abnormal phenomenon, shut down the machine immediately and continue after finding the cause.

4.5.1 Power-on

 ———————————————————————————————————————

 Notice :

This part can be carried out only after all the check results in the pre-power-on checklist are "satisfied", and the power-on operation is carried out according to the following steps.

———————————————————————————————————————

Step 1 After confirming that all system cables ( including terminals ) are correctly connected, reinstall the DC side baffle.

Step 2 Ensure that the AC input circuit breaker and the circuit breaker in the AC distribution cabinet are both turned OFF.

Step 3: Close the front circuit breaker and remove the baffle under the AC compartment; measure the line voltage between the AC input copper bars U, V, and W, which should be between 360 VAC and 440 VAC; reinstall the baffle.

Step 4: Ensure that the upper baffle is in place and turn on the two AC input circuit breakers Q1 and Q2.

Step 5: Remove the upper baffle and measure the line voltage between U, V, and W at the rear end of the AC input circuit breaker. It should be between 360 VAC and 440 VAC. Reinstall the baffle.

Step 6: Measure the input voltage on the upper side of the AC distribution circuit breaker. It should be between 207 VAC and 253 VAC.

Step 7 : Turn on all the circuit breakers Q5, Q6, Q7, Q8, and Q9 of the AC power distribution in sequence, and measure the output voltage at the bottom of the circuit breaker, which should be between 207 VAC and 253 VAC.
