Rules for Standard Assembling in Cabinets
The standard way of assembling in RM500 cabinets is shown below as a set of assembling rules
and a series of cabinet configurations. A standardized placing order will be used for the physical
location of items (such as power supplies, modems, subrack etc.) in the cabinets.
Below follow some general assembling rules applying to Advant Controller 450 with S100 I/O:
• Place the cabinets side by side (close to each other with no plates between the cabinets).
• The delivery will be in a combination of single and double cabinets.
• An I/O subrack is not filled with more than 18 boards (17 boards if redundant S100 I/O bus
extension is used), two empty slots will be spare for future expansion.
• The number of boards in an I/O subrack is limited either by the 18 (17) boards in the
subrack or by the available space for connection units.
• In each double (single) cabinet space for 1 mounting bar (for connection units) is left for
future expansion.
Advant Controller 450 with S100 I/O in RM500V1 Cabinets
• The delivery is assembled in up to six cabinets, for the controller subrack and the five
possible I/O subracks that can be connected to the same electrical S100 I/O bus extension.
• An extra cabinet, in the configuration figures below showed as the cabinet no 7, can be
added to the right of a given configuration, if necessary, to house connection units. For
connections units in the extra cabinet, cables with extended length have to be used from
the I/O subracks.
• With the cabinet housing the controller subrack to the left, the expansion direction is to the
right.
• Cabinet no 1, 4 and 6 contain no hinged frame.
• I/O subracks can not be placed in cabinet no 6 or 7 as the S100 I/O bus extension cable
exceeds 12 meters (39 ft.).
• Modems are always placed in cabinet no 1 in a modem subrack. For maximum four
modems, mounting plates to the left of the controller subrack is used instead.
• All cabinets that share the same S100 I/O bus extension (max 12 m) are connected to the
same power switch placed in the cabinet housing the controller subrack.
• Cabinet no. 1, 3 and 5 have their own power supplies (power switch in no 1).
• One set of power supplies for field equipment, if ordered, is placed in cabinet no 2.
• Connection units are placed only within the same single or double cabinet that houses the
corresponding I/O subrack or in the next cabinet to the right.
• The boards are placed in the I/O subracks in order AI, AO, DO, DI starting in subrack 1.
