Drive Comparisons Chapter 1

Blower Starters

(4)

14BN One NEMA size 1 full-voltage, non-reversing (FVNR) starter assembly with 30 A fuse blocks

mounted within the drive unit

14B2N Two NEMA size 1 FVNR starter assemblies with 30 A fuse blocks mounted within the drive unit

14B2NX Two NEMA size 2 FVNR starter assemblies with 60 A fuse blocks mounted within the drive unit

14BI One IEC, 24 A starter assembly mounted with 30 A fuse blocks within the drive unit

14B2I Two IEC, 24 A starter assemblies mounted with 30 A fuse blocks within the drive unit

14B2IX Two IEC, 30 A starter assemblies mounted with 60 A fuse blocks within the drive unit

Protection 14LSP Line RC suppressor module

14AFL Air flow loss switches

Input Option

(7)

14HBC AC power input is wired from the horizontal thru-bus to the circuit breaker

Field Supply Upgrade

(8)

14FX Field supply upgrade for fields requiring 43…90 A

Field Voltage Step-down Options for Units with 575 or 660V AC Input

(9)

14SD28 Field transformer for field currents up to 28 A

14SD40 Field transformer for field currents up to 40 A

14SD90 Field transformer for field currents up to 90 A

Miscellaneous 14WLBL Brady Datab wire labels

(1) Devices are 800T-type.

(2) Maximum number of cards allowed is one for Port A, and one for Port B.

(3) If your motor has a DC tachometer, select the appropriate scaling board.

(4) You may select one option from this group.

(5) You must select one option from this group.

(6) For 1250…3000 A modules, you may select option “14DB.” This option includes a dynamic braking contactor mounted in a separate 20 in. MCC section.

(7) This option is only valid for 1250 A and 1650 A DC drives. You must specify an AC thru-bus option with a current capacity larger than the continuous input current rating of the drive unit.

(8) Units come standard with a field supply module rated to supply field currents up to 43 A. This field supply option allows you to supply up to 90 A to the motor field. If you are selecting a 575V or 660V AC

input and this field supply option, you must select field voltage step-down option “14SD90”.

(9) Units configured for 575V or 660V AC input require field transformers. The field supply modules require an input voltage of 460V AC and the field transformer is utilized to step-down 575V or 660V AC

input to 460V AC. The base unit price of a 575V or 660V AC input drive includes a field transformer (and fusing) that provides up to 18 A to the field supply module. Select a field transformer upgrade

option when you need to supply more current to the field supply module. All field transformers come standard in a NEMA/UL Type 1 enclosure. Nominal field currents based on 85% efficiency, unit control

power usage, and a 300V field supply.

(10) If selected, you must also select option “1B.”

(11) The line RC suppressor is recommended for installations where the primary of the distribution transformer is 2300V AC or greater.

(12) Units come standard with cloth wire labels. Datab labels offer the added protection of a clear plastic cover on top of the labels.

(13) Customer supplies 115V AC control power and wiring to the duplex receptacle.
