Description

PMA44P-10100-00 motor power supply voltage

PMA44P-10100-00 motor power supply voltage

The following requirements must be met to ensure compliance with the Low Voltage Directive:

• Never connect or disconnect any drive connectors or terminals while the power is switched on.

• The climatic conditions shall be in accordance with EN 50178 climatic class: Type B, temperature and relative humidity: Class 3K3.

• This drive is to be installed inside a motor/control cabinet accessible by qualified personnel only.

• Electronic drives contain electrostatic sensitive devices which can be damaged when handled improperly. Qualified personnel must follow ESD protection measures. For example: wear grounded heel and wrist straps when contacting drive.

• The discharge time for the bus capacitors may be as long as 5 minutes. After disconnecting the drive from the ac mains be sure to wait 5 minutes before removing the drive’s cover and exposing live parts.

• Follow IEC 536-2 and IEC 1140 for installation protection against electric shock.

• Installation shall be performed in accordance with local electric codes, local accident prevention rules, EN 50178 and EN 61800-3.

• Due to high leakage current this drive is to be permanently installed, i.e. hard wired. The PE connection shall be made by two separate conductors between the earth ground and the two PE terminals on the device.

• Consult the factory before using this product on a circuit protected by a residual-current-operated protective device (RCD).

• External, supply line, fusing is required. PC833: Bussman, MDA-20, PC834: Littlefuse, FLM 30.

• Motor cable shield must be connected to protective earth.

• All covers shall be closed during operation.

• During periods of extreme regeneration or excessively high input voltage the temperature of the regen resistor may exceed 70 °C.

• When using an external regen resistor, if regen cabling is accessible during normal machine operation, regen resistor cable should be rated at 450 VDC and shielded with shield connected to PE.

DCS control system has a wide range of applications in the power industry, and is the most critical and important system for automation control in thermal power plants. As the neural center of the production system in thermal power plants, the safe and stable operation of the DCS system plays a decisive role in the safety production of thermal power plants.

The DCS system is based on microcomputers and integrates technologies such as computer, communication, display, and control. It consists of a process control level and a process monitoring level, and its main characteristics are centralized management and decentralized control. Specifically, the DCS system consists of controllers, I/O modules, communication networks, operation stations, engineer stations, historical stations, graphics and programming software, among which the communication network is the link and backbone of the DCS system. The DCS control system adopts the basic design concept of decentralized control, centralized operation and management, and adopts a multi-layer hierarchical, cooperative and autonomous structural form.

Since its inception in 1975, DCS systems have been rapidly promoted and developed, and currently have reached a high level of stability in core hardware. A DCS system controller and I/O components can usually operate stably for 16 to 20 years, and only the operating station is frequently updated due to the presence of active components (such as hard drives, keyboards, CRTs, external interfaces, etc.) and software. Therefore, the unsafe factors of the DCS system in thermal power plants are mainly concentrated in communication networks and operation stations.
