2.4.2 Electrical Connections
NOTE:
This procedure assumes the use of a ABB model ACS800 Motor Drive but it can be applicable
for other makes and models. Only basic instructions are provided with references to the manufacturers
installation guide for specific details or information. If a manual was not included with the AC Motor
assembly, check the manufacturers website for a download version or contact SuperFlow Customer
Service with the make and model number of the motor drive.
1. Mount the primary Motor Drive unit to a suitable wall or other support
structure according to the instructions in the manufacturers installation
guide.
• The drive unit should be no further than 25 feet [7.5 meters] from the
SuperFlow sensor box for the control cables to reach. Custom length
cables can be obtained from SuperFlow if necessary.
• Maintain free space around the unit to enable cooling air flow and
service access. Follow the manufacturers recommendations or allow a
minimum of 12 inches [300 mm] on all sides.
• When installed in a closed cabinet, ensure adequate cooling through
the enclosure.

IMPORTANT:
The installation of high voltage electrical equipment must always be made
according to applicable local laws and regulations. All electrical work must only be performed by a
qualified electrician. Always follow standard safety precautions. SuperFlow Technologies Group or
it’s affiliates do not assume any liability whatsoever for any installation which breaches local laws
and/or regulations, or for any work done by un-qualified personnel. Furthermore, if the
recommendations provided in this procedure or in the manufacturers installation guidelines are not
followed, the drive may experience problems that the warranty does not cover.
2. Install a hand-operated disconnecting device (switch) between the AC power source and the
motor drive. The disconnecting device must conform to the applicable safety regulations and
be of a type that can be locked to the open position for installation and maintenance work.
3. Follow the procedures and precautions for installing the motor drive as outlined in the
manufacturers guidelines or manual. With any installation, always consider the following
recommendations.
• Ensure the electrical power source has thermal overload and short-circuit protection. Follow
the manufacturers guidelines or use a suitable 200 Amp breaker in the power circuit.
• Select the cable size according to local regulations based upon the rated drive load current.
600 VAC cable is normally accepted for up to 500 VAC.
• Ensure a common ground between the motor drive, motor, resistive load bank, and source
power.
• Shielded symmetrical motor cable is recommended. However, shielded cable is not
necessary when continuous conduit is used.
• It is recommended that the power cable, motor cables, and load bank cables be installed in
separate conduits or cable trays. High voltage cables should never be run alongside control
cables or low-voltage wiring.
