Technical data of product parameters
AB 1756-RM frequency converter module
• Cabinet dimensions: 800 mm (W) x 800 mm (D) x 2,000 mm (+100 mm) (*1) (H).
*1: 100 mm is the height of the channel base.
• Door fans must be mounted on both front- and rear-door panels. (Both fans’ air flow rate
should be equal or greater than 230 m3
/h.)
Temperature Condition
The ambient cabinet outside a cabinet must be below 40 degree Celsius.
The ambient temperature inside a cabinet where the Field Control Unit and the FIO Node Units
are installed must satisfy the conditions specified in GS (General Specification)documents of the
Field Control Unit and the FIO Node Units.
Installation Condition AB 1756-RM frequency converter module
• Maximum Number of Devices
Field Control Unit: One each can be installed in front part and rear part of a cabinet.
Node Unit: Four each can be installed in front part and rear part of a cabinet.
If Field Control Unit is not installed in the part of the cabinet, up to five FIO node units can be
installed.
• Any heat generating device other than Field Control Unit and FIO node unit (such as a
power supply) should not be installed in the cabinet.
• A three unit mounting space (one unit mounting space equals to 44.45 mm) should be kept
between the highest position of the mounting frame and the highest Field Control Unit or
FIO node unit in the cabinet.
• One unit mounting space (one unit mounting space equals to 44.45 mm) should be kept
between an Field Control Unit and an FIO node unit.
• Up to two FIO node units can be installed close to each other in the same cabinet.
If three FIO node units need to be installed close to each other, a circulation fan unit (with 300m3AB 1756-RM frequency converter module/h or more airflow capability) should be placed at the top of the three FIO node units.
