The feeder terminal includes two serial commu-
nication ports, one on the front panel and the
other on the rear panel.
The 9-pole RS 232 connection on the front
panel is intended for the connection of a PC to
be used for setting the CB/disconnector con-
For its operation the feeder terminal requires a
secured auxiliary voltage supply. The feeder
terminal's internal power supply module SPGU
240A1 or SPGU 48B2 forms the voltages re-
quired by the measuring relay modules, the
control module and the input / output modules.
The power supply module is a transformer con-
nected, i.e. galvanically isolated primary and
secondary side, flyback-type DC/DC converter.
The feeder terminal SPAC 536 C is designed for
flush mounting in a 19" instrument frame. The
unit is fastened with four screws. The mounting
depth can be reduced by using a 40 mm raising
frame type SPA-ZX 19.

The 9-pole RS 485 connection on the rear panel
is used to connect the feeder terminal to the SPA
bus via an interface module type SPA-ZC17_ or
SPA-ZC21_.
The primary side of the power supply module is
protected with a fuse, F1, located on the PCB of
the module. The fuse size is 1 A (slow).

There are two versions of power supply modules
available. The secondary sides of the modules are
identical, but the input voltage range is different.
The input voltage range is marked on the front
panel of the control module.
When the feeder terminal is door-mounted, the
door structure should be reinforced.
