BT300 HVAC Drives Conventional

Bypass (C-Bypass) Options

Siemens Industry, Inc.

Description

The BT300 Conventional Bypass (C-Bypass) is a

companion package for the family of BT300 HVAC

Drives.

For information on the family of BT300 HVAC Drives,

see the BT300 HVAC Drives Submittal Sheet

(154-126) and BT300 HVAC Drives Technical

Specification Sheet (149-711).

BT300 C-Bypass Features

• Bypass Start-up Wizard

• Diagnostic board with test points

• Control logic short circuit protection

• 100,000 AIC short circuit rating

• Country of Origin (COO) USA

• IBC 2012 Seismic Certified

• OSHPD Certified

• Compact design

C-Bypass Power Features

2-Contactor: Output and Bypass

• Overload protection in bypass mode

• Electrically and mechanically interlocked

Drive Isolation

• Drive Service Switch allows the drive to be

disconnected from power during troubleshooting

without disrupting bypass operation.

• Optional 3-Contactor (Drive Input)

− Contactors electrically interlocked.

− Drive test function

− Complete electrical isolation of drive

Input Device

• Disconnect with fuses.

• (Optional) Circuit breaker.

• All doors are interlocked and can be

secured with a padlock.

5% Input Impedance

• Internal reactors lower harmonics that the drive

produces.

• BT300 C-Bypass requires no additional input reactors

Reactor Options

• Line reactor (in NEMA 1 enclosure) supplied separately.

• Load reactor (in NEMA 1 enclosure) supplied separately.

C-Bypass Control Features

• Enable Input

Generally used for safety tie-ins; the motor will not

operate the drive or bypass when open.

• Common Remote Start/Stop

Common remote start/stop can be used in both drive and

bypass mode.

• Essential Services Mode

− Typically used for smoke purge; the motor goes to

bypass regardless of the selected mode.

− No call to stop will have an effect, including open

safety or stop commands.

− Only turning the power off or opening this contact

will stop the motor.

• Drive-Off-Bypass selector

• Bypass pilot light

• Drive Test on/off selector (with third Contactor)
