CI840 and CI801 (PROFIBUS DP interface for S800 I/O) which also powers all S800 I/O units connected to its electrical ModuleBus. • PROFIBUS DP adapters for other I/O systems (depending on the supply arrangement for the I/O units, it may be necessary to connect power to each I/O unit). • Communication modems located in the cabinet. The main configuration rule for this power supply is to retain the 24 V cables within the cabinet. Powering Field Equipment outside the Cabinet This is intended for supplying power to process signals and equipment located outside the cabinet. Interference Powering field equipment from a power supply located in the AC 800M Controller cabinet often requires the use of long 24 V DC cables that can easily pick up local interference and direct it straight back to the power supply units. When installing the cables, follow the instructions for Field Cables, given under Cables on page 62. Short-Circuit at Power Supply Output The SD83X series power supply has no extra energy reservoir at its outputs. In the event of a short circuit the power supply output voltage will fall rapidly. Short circuits (even with fuses installed in the 24 V DC distribution system) or large load changes can produce unwanted voltage dips in supply
To avoid the AC 800M Controller being influenced by field equipment, it is strongly recommended that separate power supplies be installed (see Figure 50 on page 147 and Figure 51 on page 148). Sectioning Field Equipment If field equipment connected to an AC 800M Controller is to be sectioned into groups – thus avoiding a power failure in one group from influencing the power to other groups – then it is recommended to use separate power supplies for each field equipment group. The use of fuses in the 24 V DC distribution system is not a fail-safe measure. If a short circuit occurs in one group, then voltage will most likely drop before a fuse blows; consequently all groups will experience a drop in voltage. Cable Protection 24 V DC distribution system cables must be fuse-protected. In order to allow for overload/short circuit situations, the power supply output current is limited. Allow the power supply an extra capacity of at least 3-4 times the rated current value of the largest connected fuse and remember to include long cable resistance in the calculation.
