The ModuleBus for PM891 has a fiber optical interface. The interface is designed
for a maximum of seven clusters, of twelve non-redundant or six redundant modules
(that is, 7x12 = 84 modules). Redundant and non-redundant modules can be mixed.
The fiber-optical interface is intended for local distribution of I/O clusters. .
Figure 41 on page 132 provides details of the fiber optic connectors, together with
the PM891 optical ModuleBus ports.

3BSE036351-510 A 133
Installing the SD83x Power Supply
The SD83x power supply units (SD831 / SD832 / SD833 / SD834) should be
mounted horizontally at a DIN rail. The units have to be used in non-hazardous
locations only.
The four PSUs have data as follows:
– SD831 = Input a.c. 100-240 V or d.c. 110-300 V.
Output d.c. 24 Volts regulated @ 3 A.
– SD832 = Input a.c. 100-120 or 200-240 V.
Output d.c. 24 Volts regulated @ 5 A
– SD833 = Input a.c. 100-120 or 200-240 V.
Output d.c. 24 Volts regulated @ 10 A
– SD834 = Input a.c. 100-240 V or d.c. 110-300 V.
Output d.c. 24 Volts regulated @ 20 A
Internal primary main fuses are arranged to meet the requirements of electrical
safety publications for connection to the Phase - Neutral terminals of primary main
network; TN network, 1 (one) fuse. When SD831 and SD834 are used with d.c.
input, connect + terminal to L and - terminal to N.

Installing the Mains Breaker Unit Section 2 Installation
134 3BSE036351-510 A
Installing the Mains Breaker Unit
The mains breaker unit is supplied in separate components that must be mounted
onto a DIN-rail in order to form a complete assembly. Different distribution options
are available, see Figure 61 on page 177 and Figure 62 on page 178. For the sake of
simplicity, the installation described covers the redundant power
supplies/independent power supplies option.
Use the following procedure to correctly install the mains breaker unit:
1. Mount the mains breaker unit components onto the DIN-rail, from left to right,
close to the incoming power supply, in the order given below (see Figure 42 on
page 135).
a. A DIN-rail end-stop (1).
b. The terminal for the incoming protective ground (2).
c. The two terminals for the incoming Live and Neutral mains power (3).
These terminals are equipped with built-in jumpers which, if necessary,
can be opened to provide complete mains input power isolation.
d. The miniature mains breaker unit (4).
e. The protective ground distribution terminal (5).
f. The mains distribution terminal block (6), depending on the required
configuration.
g. A DIN-rail end-stop (1).
2. Connect the incoming mains, the protective ground terminals, the mains
breaker and the distribution terminals as shown in Figure 42 on page 135.
3. Install the two required links (7), fuse holders (8) and jumpers (9) onto
the distribution terminals. Fit the required fuses into the fuse holders, (glass
tube type, 5 x 20 mm (0.2 x 0.8 in)).
The protective ground terminal (2) is fitted with a knife-like device to provide
automatic grounding to the DIN-rail.
