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. Section 2 Installation Installing the Mains Breaker Unit 3BSE036351-510 A 135 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. Figure 42.

Depending on the system configuration requirements, the two redundant power supplies may be connected to completely separate mains supplies or to the same mains supply, as shown in Figure 43 on page 137 for SS823, Figure 44 on page 138, and Figure 45 on page 139 for SS832. Use the following procedure to install the voting unit SS8xx: 1. Mount the voting unit SS8xx onto the DIN-rail, adjacent to the power supplies. 2. Connect the voting unit to the selected SD83x power supply units, in required configuration. See Figure 44 on page 138 and Figure 45 on page 139 for SS832.

Figure 46 on page 140 shows the connection to PM861/PM864/PM865 in redundant configuration. Figure 45.

Redundant Power Supply Powering Redundant CPUs From Mains Breaker Protective Ground Section 2 Installation Installing the SS823/SS832 Voting Unit 3BSE036351-510 A 141 Power Supply Supervision The status of power supplies in redundant configuration can be supervised via the SS8xx voting unit. The supervision signals SA and SB from the SS8xx are connected to the corresponding terminals of the CPU. + 24 V on the SA/SB indicates working power supplies. 0 V on SA/SB indicates an error in the corresponding power supply and lack of redundancy. SA/SB signal connection is shown in Figure 46 on page 140, Figure 47 on page 141 and Figure 48 on page 142. Figure 46 on page 140 show redundant power supplies powering AC 800M units. Here the SA/SB signals also indicate physical power supplies. Figure 48 on page 142 shows one redundant power supply powering the AC 800M units and one for powering field equipment. An SA/SB error indication can not indicate which physical power supply that has failed, only that there is a failure. Figure 47. Connection of SA/SB using Single Power Supply To avoid error indications from SA/SB when single power supply is used, it is recommended to connect the input terminals SA/SB on the CPU to +24 V, see Figure 47. +24 V 0 V Installing the SS823/SS832 Voting Unit Section 2 Installation 142 3BSE036351-510 A Figure 48.

Mount the SB821 external battery unit at a suitable position on the DIN-rail. 2. For connecting the SB821 external battery unit, use the 2 m (2.2 yd) cable TK821V020. Plug one end into the battery unit and the other into the external battery supply socket of the PM8xx processor unit (see Figure 2 on page 32). 3. In redundant CPU configuration containing two PM861/PM864/PM865 processor units, use also two SB821 battery units, one for each processor unit. 4. Due to the batteries being connected in parallel, it is necessary, when using the external battery, to remove the internal battery from the PM8xx in order to avoid reducing available memory back-up time. Do not connect the TK821V020 cable until the AC 800M Controller has been powered-up normally and the memory back-up function has been activated, that is, the B(attery) LED flashes. If no normal power supply is connected to the PM8xx processor unit, the CPU memory will immediately start to consume battery power when the cable is connected. Always install a fresh internal or external battery at the end of the installation phase. The original battery is heavily utilized due to frequent blackouts during system installation.
