Precautions for the use of Rittal electrical cabinets

1. Disconnect the power supply, check whether the rack of the control cabinet has reliable grounding, and make the grounding resistance not greater than 4Ω. 2. There are voltages of different properties on the control cabinet (DC 110V; Communication single-phase 220V; Three-phase communication), the circuit must be distinguished during maintenance to avoid short-circuit accidents.

1. The Rittal air conditioner does not start when it is turned on, and the A17 is faulty. Check that the power supply voltage is 220V, normal; Detect that the battery voltage of the remote control is 3V, which is normal; Measure the fuse resistance value of the air conditioner compressor with a multimeter as infinity, which is normal. 2. The Rittal air conditioner does not start when it is turned on, and the display is not started.

In the high-voltage cabinet with the spring energy storage operating mechanism, the energy storage must be stored in advance before closing. The energy storage mechanism is driven by an electric motor and the gear mechanism lengthens the spring. There are two types of operation methods: electric and manual. Manual failure to store energy should be due to a mechanical failure of the mechanism. Manual energy storage ...

1. The elevation or verticality of the distribution box (panel) exceeds the allowable deviation: it is caused by inaccurate measurement and positioning or uneven ground, and should be corrected in time. 2. The iron frame of the distribution box is not square: the iron frame is not straightened and aligned before the installation of the iron frame, or the position of the fixed point is deviated during installation.

First, the construction process Equipment unpacking inspection→ equipment handling, → cabinet (plate), basic installation, → above the cabinet (plate), bus preparation, → cabinet (plate), secondary circuit wiring, → cabinet (plate) test adjustment, → power transmission operation acceptance Second, the construction process 1. Equipment unpacking inspection, installation ...

What is a busbar? Answer: In the voltage distribution devices at all levels of power plants and substations, the wires connecting engines, transformers and various electrical appliances are called busbars. What is the classification of busbars? Answer: soft bus (mostly used in outdoor power distribution room with high voltage) and hard bus (low ...

An introduction to Rittal switchgear The switch cabinet is a kind of electrical equipment, the outer line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. Such as instrumentation, automatic control, motor magnetic switch, all kinds of AC contactors, etc., ...

1. Deliver the cold air to the network cabinet: Because the equipment in the cabinet needs the air conditioning the most. 2. Deliver the cold air to the front of the network cabinet: because the cold air can only enter the module server chassis from the front of the server to play a role in heat exchange. 3. Precisely adjust the ...

1. Buried laying The laying method of laying the cable immediately underground is called buried laying. The buried cable must be armored cable and anti-corrosion coating protection cable, and the bare cable cannot be buried. Generally, the depth of the cable trench shall not exceed 0.9m, and the buried laying shall be paved ...

1. Avoid light The server is required to operate in a constant temperature environment, and direct sunlight will increase the temperature in the computer room, which will damage the display and shorten its service life. When operating in IDC and ISP data centers, it is impossible to see a ray of sunshine. So, in ...

Smart ships are a key area clearly supported by national policies. Driven by policy guidance and innovation, China has achieved phased results in the research and construction of smart ships. As the world's leading provider of enclosure systems, Rittal has a wide range of applications in the marine and port sectors.

(1) The cause of moisture in the cabinet 1) Environment shutdown. The ring main unit or the opening and closing station itself is a closed environment, because of the poor ventilation conditions, it is easy to gather moisture and generate condensation, and there are many large buildings today in order to reduce the occupied area, the opening and closing station, the power distribution room is built in the basement. Cause...

The quality and brand awareness of Rittal are good, and the application market is also large, but due to various reasons such as price, delivery time, service, etc., many customer groups do not want to use Rittal products, but choose to go to the manufacturer to order imitation Rittal products. ...

1. It is not displayed at that time. Solution: Check whether the sample signal cable is not connected. 2. Whether the fuse core of the controller in the cabinet is burned out. Solution: Remove the burned out fuse core and replace it with a new one. 3. The voltage of the distribution cabinet is too high, and the overvoltage alarm. Workaround: Re...

Server cabinets have requirements in terms of depth, height, and load-bearing capacity. There are three heights of 2.0 meters, 1.8 meters and 1.6 meters; The width is 800mm, 700mm or 600mm; There are three depths: 700mm, 800mm and 900mm. Can be configured: special fixed pallet, special ...

(1) Classified according to the requirements of the power supply system 1) The first-level power distribution equipment is collectively referred to as the power distribution center. They are centrally installed in the substations of the enterprise, and the electrical energy is distributed to the subordinate distribution equipment in different locations. This level of equipment is close to the step-down transformer, so the electrical parameters are high.

1. The first is to measure how long the line is. According to the decision is to put the location of the distribution frame, and then combine the distance of the cable from the outside into the cabinet and so on to calculate how long the network cable needs to be put on the distribution frame and install the cabinet, so as to facilitate the overall cable management behind.

1. Selection of wire and cable models When selecting wires and cables, it is necessary to consider the use, laying conditions and safety; For example, depending on the application, power cables, overhead insulated cables, control cables, etc. can be selected According to the different laying conditions, the general plastic insulated cable can be selected ...
