6 Installation and Dimensions

6.1Installation Information

SIMOREG Base Drive Panels are designed as chassis units intended to be mounted inside a protective enclosure or inside a control room. The units are to be mounted vertically in cubicles usually with the power connections at the top and the control connections at the bottom. A minimum 100-mm (4-inch) clearance must be kept above and below the converter in order to ensure unrestricted cooling airflow. The minimum enclosure size to be used is 23.6 by 23.6 by 86.6 inch high. The open chassis units are designed to operate in a 45°C ambient. When enclosed in a cubicle the ambient temperature outside the cubicle should not exceed 40°C, which then allows for a 5°C-temperature rise inside the cubicle. Care must be taken in the selection of the cubicle so that the internal temperature rise does not exceed 5°C. Refer to section 5 for approximate power loss data.

Note, Important: This equipment is designed and package-protected to handle the normal shock and vibration typically encountered in shipment. Do not install these Base Drive Panels on equipment subject to shock or vibration. Select a reasonably clean location for installation, free from corrosive or conductive materials or fumes.

CAUTION

Failure to lift the Base Drive Panel in the correct manner can result in bodily injury and/or property damage.

The Base Drive Panel must be lifted using suitable equipment and under the instruction of appropriately qualified personnel.

The user is responsible for installing the Base Drive Panel, motor, transformer as well as other equipment according to safety regulations (e.g. NEC), as well as all other relevant national or local regulations regarding cable sizing and protection, grounding, disconnects, overcurrent protection, etc.

The Base Drive Panels must be installed in accordance with the relevant safety regulations (e.g. NEC), as well as all other relevant national and local regulations. It must be ensured that the grounding, cable sizing and appropriate short-circuit protection have been implemented to guarantee operational safety and reliability.

Note, Important: Base Drive Panels have high-speed semiconductor fuses installed for protection of the thyristors in the event high fault currents are encountered. These fuses are “special purpose” fuses, and do not meet the requirements of the NEC for short-circuit protection in motor branch circuits. It is necessary to provide other devices for short-circuit protection. Typically molded case circuit breakers or NEC style fuses are used for this purpose. Refer to applicable sections of the NEC for additional information.

NOTE

The fundamental principles of EMC in Section 6.1 of SIMOREG 6RA70 DC Master operating instructions (Order # 6RX1700-0AD76) must be adhered to when installing any unit.
