Subracks
2-2 Hardware - SIMADYN D
Edition 04.2011
2.1 Subracks SR6, SR6V
The subracks accommodate SIMADYN D modules with the format (Hï‚´D)
233.4  220 mm².
An integrated power supply provides the necessary voltages for the modules
via the backplane bus (L bus) and permits data transfer between them.
SR6/SR6V: 6
The slots are identified by a labeling strip.
2.1.1 Power supply
The power supply (type SP7, 6DD1683-0BB0) plugs into the SIMADYN D
ES 902 C subrack system in the righthand subrack slot.
It is secured using a screw locking so that it cannot slide out and guarantees
natural air cooling (SR6) or unrestricted forced ventilation with mounted fan
(SR6V) of the subrack.
The current demand of the modules may not exceed the available output
currents of the 5 V and +/-15 V supplies (refer to the Chapter „Technical
data“). Otherwise, a larger subrack must be used, e. g. SR12.x.
ï‚· green LED green: Error-free operation
ï‚· red LED: Fault condition
ï‚· reset button to restart modules
ï‚· connection for the supply voltage (screw/plug-in terminal X1)
ï‚· connection for an external back-up battery (screw/plug-in terminal X2)
ï‚· test sockets to check the 3 output voltages 5 V, +/-15 V
(short-circuit protection is provided via protective resistors)
The 230 V supply voltage is fed-in via the 4-pole screw/plug-in terminal X1.
The connection assignment is printed on the front panel:
