2.4 Specifications

- The more important specifiĆ

cations for the FlexPak Plus controller are listed in Table

2.B. Refer also to Table 2.D where other ratings are indiĆ

cated in relation to dĆc motors of specific horsepower.
2.4.1 Line Frequency - The FlexPak Plus controller is

able to operate without modification from a threeĆphase

power source having a frequency range from 48 to 62

Hz.
2.4.2 Voltage Tolerance - The FlexPak Plus controller

delivers output current and voltage, as listed in Table

2.D. It will also operate within these regulation specificaĆ

tions even with incoming line voltage at +/Ć10% of nomiĆ

nal.
2.4.3 Line Impedance Requirements - The FlexPak

Plus controller must be connected to a plant power supĆ

ply with maximum permissible available symmetrical

RMS fault current no greater than 5000 amperes. (Refer

to Table 2.D.)

WARNING

DO NOT OPERATE THE FLEXPAK PLUS CONĆ

TROLLER ON POWER SUPPLIES WITH AVAILĆ

ABLE SHORTĆCIRCUIT CURRENTS IN EXCESS

OF 5000 AMPERES. DAMAGE TO EQUIPMENT

AND PERSONAL INJURY MAY OCCUR. EXTERĆ

NAL DISCONNECT MEANS MUST HAVE ABILĆ

ITY TO INTERRUPT A 5000 AMP RMS CURRENT

FAULT.

2.4.4 Relay Control Circuit - The regulator board is

set up for use with 24 VDC main contactors having a coil

resistance greater than or equal to 100 ohms, 14C300

only; 14C301 to 14C305 is 1000 ohms. The control logic

sequences the contractor and the control relay on the

regulator so that current flow thru the main contactor is

never broken in normal operation by the contracts. ReĆ

fer to Figures 5.1, and 5.2.
The standard controller includes an M contactor. HowĆ

ever, the Optional Basic Controller does not have an M

contactor. An M contactor is required to provide positive

power disconnect in all applications.
