3.4.2.1 REMOTE SHUTDOWN
A standalone unit can be shut down using a remote signal applied to the PROTECTION EXT.
PORT as shown in Figure 3-15 or 3-16 or by a remote control applied at PAR/SER PROTECT
PORT IN as shown in Figure 3-17. A multiple unit configuration (parallel, series or series-paral-
lel) can be disabled by applying a remote signal to the master PROTECTION EXT PORT as
shown in Figure 3-15 or by applying a remote control to PAR/SER PROTECT PORT IN as
shown in Figure 3-17. The method shown in Figure 3-17 must first be enabled as described in
PAR. 2.7.3 Once enabled, there must be continuity between pins 6 and 7 of PAR/SER PRO-
TECT PORT IN in order for the unit to function. This feature can also be used as a fail-safe to
shut down the unit in case of inadvertent disconnection of the PAR/SER PROTECT PORT IN
cable. When the signal is momentarily active (minimum 100

S
), power transfer between input
and output is stopped (both input and output internal modules are shut off). This condition is
latched and requires the unit to be turned off, then on again to restore normal operation.
