Environmental ratings Power Electronics recommends following the instructions in this manual carefully to ensure a correct operation of the drive. The installer is responsible for performing a proper installation in order to comply with the ambient conditions of the VFD. In addition, the installer is solely responsible for complying with the local regulations.
This section contains assembly instructions for optimum operation of the drive and precautions to avoid personal injury and property damage. SD750FR drives are designed to be placed over a technical floor, vertically. The floor must guarantee a non-flammable, solid, plain and levelled surface to the drive, a minimum clearance around it and a smoothly cable access.
POWER ELECTRONICS SD750FR Clearances Keep always the minimum passage width between the opened door of the SD750FR and the next fixed obstacle. The minimum passage width must comply with national standards. The recommended minimum passage width is 500 mm. The cabinets can be installed against a wall or back-to-back with another unit in their rear and side parts.
The heat sources inside the equipment correspond with the inverter and rectifier bridge (IGBTs), input filter and the output dV/dt filter. SD750FR series present an overall efficiency higher than 97% at rated power, so the heat dissipation approximately corresponds to 3% of the input power.

POWER ELECTRONICS Reference cable section The following tables show the reference cable section for each SD750FR frame, based on the internal drive sections. The installer must consider the cable cross-section, cable type, wiring method and ambient conditions to select the appropriate cable to be installed between the drive and the motor.
SD750FR POWER ELECTRONICS Ground connection Before connecting the power conductors, make sure that the chassis of the drive and the adjoining cabinets are connected to ground through the dedicated (PE) terminals. These are situated at both sides of the bottom metal walls of the drive and they are labeled with the earth symbol. Check section “Power Terminals”.
POWER ELECTRONICS SD750FR EMC installation requirements Introduction The EMC European Directive defines electromagnetic compatibility as the capability of an apparatus, an industrial plant, or a system to work satisfactorily in the electromagnetic environment without at the same time causing electromagnetic disturbances in the apparatus, industrial plant or systems present in the same environment.
Environment) by employing optional RFI filters that permit to achieve the C2 category. The SD750FR is not a retail unit. It is neither a plug in device nor a movable device and it is intended to be installed and commissioned by qualified personnel. Therefore, C1 category will not be required.
Protections Short circuit The SD750FR includes from frame 5 to 8 ultra-fast input protection fuses as standard. Frame 5 includes one fuse per phase with a rated current that depends on the drive’s nominal current. From frame 6 upwards, the fuses per phase depend on the number of modules (frame 5) interconnected. The main characteristics of these fuses are shown in the following table.
The SD750FR drives are suitable to operate with RCD components Type B, if it is required. The EMC / EMC filters and motor cable lengths increase the earth leakage currents, so the protection range is set according to the installation conditions.
VFD’s, can demand a high current causing high voltages and current transients. SD750FR drives are by default in compliance with IEC/EN 61800-3 product standard “Adjustable speed electrical power drive systems - Part 3: EMC requirements and specific test methods”. Dip test levels are defined in IEC 61000-4-34 “Voltage dips, short interruptions and voltage variations immunity tests...
SD750FR POWER ELECTRONICS Other protections Apart from the protections mentioned above, the drive implements additional protections such as temporary loss of power, automatic re-start, high and low input and output voltage, overload or underload of the pump, etc. For further information, consult the Software and Programming Manual.
