PROTECT IN PORT

(A2A5J1)

1

SD_A

Anode of LED optocoupler which is part of protection circuit for parallel
or series combination. Cathode of LED is connected to PARALLEL/
SERIAL PROTECT OUT PORT (A2A5J2) pin 1 (see Table 2-9). When
activated, the optocoupler shuts down the unit. LEDs from all units of the
parallel or series combination are connected in series.

2

PGOUT_C

Collector of optocoupler transistor which is part of protection circuit for
parallel or series combination. Transistor emitter is connected to PAR-
ALLEL/SERIAL PROTECT OUT PORT (A2A5J2) pin 2 (see Table 2-9).
When unit is operating normally, transistor is saturated. Transistors from
all units of the parallel or series combination are connected in series.

3

SD_RETURN

Completes return connection for the protection circuit which receives
energy from the master unit.

6

No connection

7

GND

Local power ground.

8

ALLOW EXT_ERR Provides energy for the protection circuit (master unit only). Disabled at

power up to prevent shutdown during power up.
