2.4 .3 Line Impedance Requirements - The FlexPak Plus
controller must be connected to a short-circuit protec tion
syste m design ed to operat e on plant power supplies with
maximum permissible available symmetrical RMS fault
curren ts of 5000 amperes. (Refer to Table 2.D.)
The Basic Contro lle r does not have an M contactor. An M
contactor is requ ired to provide positive power disconnect.
WARNING
THE USER MUST INSTALL AN M CONTACTOR
THAT HAS A 24
voe COIL WITH A MAXIMUM
CURRENT DRAW OF 150 MILLIAMPS . FOR TIM-
ING, A 200 MICROFARAD CAPACITOR MUST BE
INSTALLED WITH CORRECT POLARITY ACROSS
THE RELAY COIL. THE CONTACTOR ADAPTER
KIT MUST BE INSTALLED WITH THE USER'S M
CONTACTOR . (REFER TO TABLE 5 .A AND
PARAGRAPH 5. 14 .) PERSONAL INJURY MAY
OCCUR IF THIS IS NOT INSTALLED.
WARNING
DO NOT OPERATE
THE FLEXPAK PLUS CON-
TROLLER ON POWER SUPPLIES WITH AVAIL-
ABLE SHORT -CIRCUIT CURRENTS IN EXCESS
OF 5000 AMPERES . DAMAGE TO EQUIPMENT
AND PERSONAL INJURY MAY OCCUR.
2.4 .4 Relay Control Circuit -
The regulator board is set
up for use w ith main cont actors having a coil resistance
greater tha n or equal to 100 ohms . The control logic
sequences the contacto r and the control relay on the regu-
lator so that current fl ow thru the main contactor is never
broken in normal operation by the contacts. Refer to Fig-
ures 6. 1, 6.2 and 6.3.
2.4 . 5 A-C Line Fuse Requirements - A-c line protection
is provided when the A uxi liary Panel is specified. The Basic
FlexPak Controller , however , does not include a-c line pro-
tection . Fused a-c line protection mu st be used . Refer to
Table 2.C for proper fuse sizi ng.
