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)).

Removing the fuse holders or the jumper connections provides visual indication if the power supply has been disconnected. The fuse holders have built-in red LEDs to indicate a ruptured (defective) fuse.
