All external conductors are connected to the
terminal blocks on the rear panel. Terminal
block X0 is a fix-mounted screw terminal block
fastened to the energizing input module. The
connectors X1...X3 are detachable-type multi-
pole connector strips equally with screw termi-
nals.
The male part of the multi-pole connector strips
are attached to the mother PC board. The
female parts of the detachable connector strips
are delivered as loos parts together with the
feeder terminal. The position of the female
connector strips can be secured by means of
fixing accessories and screws at the ends of the
connector.
The measuring signal inputs, auxiliary voltage
supply and OPEN and CLOSE contact outputs
are connected to the terminal block X0. Each
terminal is dimensioned for one 4 mm

The signalling contact outputs are connected to
the multi-pole connector X1. The inputs
CHANNEL1...3 and CHANNEL4...8 are
connected via connector X2. Input CHAN-
NEL9 is wired via connector X1 and the two mA
inputs via connector X3. One max. 1.5 mm
wire or two max. 0.75 mm
connected to one screw terminal.
The rear panel of the feeder terminal is provided
with a serial interface for the SPA bus (RS 485).
Two types of bus connection modules are avail-
able. The bus connection module type SPA-
ZC21 is fitted directly to the 9-pin D-type
subminiature connector. The bus connection
module SPA-ZC17 includes a connection cable
with a D-type connector. Thus the connection
module can be installed at a suitable place in the
switchgear cubicle within the reach of the con-
nection cable.
