Specification Guide for

Siemens BT300 HVAC Variable Frequency Drives

Division 15/16

Part 1 - General

1.01 Description

This specification covers the complete Variable Frequency Drive (VFD) consisting of a pulse width modulated (PWM)

inverter designed for use on a standard Type Design B induction motor. The drive shall be manufactured by Siemens, be

designed specifically for variable torque applications, and shall be designated “BT300 Series” or approved equal.

The drive manufacturer shall supply the AC drives and all necessary controls as herein specified. The manufacturer shall

have been engaged in the production of this type of equipment for a minimum of fifteen years.

1.02 Quality Assurance

A. Referenced Standards:

1. Institute of Electrical and Electronic Engineers (IEEE)

a) Standard 519-1992, IEEE Guide for Harmonic Content and Control

2. Underwriters laboratories

a) UL508

b) UL508C

3. National Electrical Manufacturer’s Association (NEMA)

a) ICS 7.0 AC Adjustable Speed Drives

4. International Electro technical Commission (IEC)

a) EN/IEC 61800-3

5. National Electric Code (NEC)

a) NEC 430.120, Adjustable-Speed Drive Systems

B. Testing:

PAGE 2
All printed circuit boards shall be completely tested and burned-in before being assembled into the completed VFD. All testing and manufacturing procedures shall be ISO 9001 certified. Test reports for each drive supplied shall be available upon delivery. C. Qualifications: VFDs and options shall be UL508 and cUL listed as a complete assembly. The base VFD shall be UL listed for 100 kA SCCR.
PAGE 3
All VFDs shall have the following standard features: 1. All VFDs shall have the same customer interface, including digital display and keypad, regardless of horsepower rating. The keypad is to be used for local control, for setting all parameters and for stepping through the displays and menus. The keypad shall be removable, capable of remote mounting and have its own non-volatile memory. The keypad shall be capable of uploading and downloading of parameter settings as an aid for start-up of multiple VFDs.
PAGE 4
MWh meter Digital input status Digital output status 11. The VFD’s shall include a Quick Start-up wizard that leads the user through the typical HVAC required parameters. 12. The VFD shall have the ability to automatically restart after an overcurrent, overvoltage, undervoltage, or loss of input signal protective trip. The number of restart attempts, trial time, and time between reset attempts shall be programmable. 13.
PAGE 5
2. A custom PID preset for HVAC and fluid systems, allow a pressure or flow signal to be connected to the VFD, using the microprocessor in the VFD for the closed loop control. A sleep mode shall be included in the PID functions. This feature shall allow the motor to be stopped when at minimum speed for a user defined period, for additional energy savings. 3. Two (2) programmable analog inputs shall accept a current or voltage. 4.
PAGE 6
18. All VFDs shall include EMI/RFI filters. The filters shall allow the VFD assembly to be CE marked and meet product standard EN 61800-3 for the First Environment restricted level (Category C2). 19. The VFD shall have an optional integrated disconnect switch which will not add any additional enclosures to the drive and be the same footprint as a drive without an integral disconnect switch. 20. The VFD shall have the following protection circuits.
PAGE 7
(in amps), % torque, power (kW), relay outputs, digital inputs and diagnostic warning and fault information. Additionally, remote (LAN) VFD fault reset shall be possible. A minimum of 15 field parameters shall be capable of being monitored. Optional Features Optional features shall be furnished and mounted by the drive manufacturer. All optional features shall be UL Listed by the drive manufacturer as a complete assembly and carry a UL508 label.
PAGE 8
• User selectable essential service shall be provided that allows a contact closure to operate the motor at full speed, ignoring all calls to stop. • Contactors shall be interlocked to ensure that both the drive output and bypass contactors do not close simultaneously. • Two safety inputs shall be available for customer connecting. If either of these inputs opens, the electronic bypass will not operate the motor in bypass or drive mode.

Part 3 – Execution 3.01 Installation Installation shall be the responsibility of the mechanical contractor. The contractor shall install the drive in accordance with the recommendations of the VFD manufacturer as outlined in the installation manual. The electrical contractor shall complete power wiring. The contractor shall complete all wiring in accordance with the recommendations of the VFD manufacturer as outlined in the installation manual. 3.
