4.11 Backplanes – connections
Safe-area circuit connections are made to the backplane in one of
two ways – either by multiway connectors (BPMH16) or by screw
clamp terminals (BPSH16 & BPSH16-32). The following sections
explain the methods for connecting these two types.
Power supply and data connections are also made to the backplanes.
See section 4.5.3 for power connections and 4.5.4 for data
connections.
4.11.1 BPMH16 – multiway connector
The BPMH16 backplane is provided with a 38-way Elco male
connector for the 16 safe-area circuits. The mating female connector
can be obtained as an accessory (MTL part number ELC38).
The ELC38 consists of the following Elco parts:
Connector part no.: 58-8016-038-000-059
Crimps (39 pieces) part no.: 60-8017-0513-00-339
The connection procedure is:-
Check pin assignment for the MTL4041A/B/P as per figure 4.17.
Check pin assignments for the MTL4046/C/P as per figure 4.18.
Using the crimps provided, make the appropriate connections to
the mating half of the multiway Elco connector according to the pin
assignments detailed in Table 4.1 and Figure 4.16.
Complete connector tag label and attach to the backplane
(optional).
Plug multiway connector onto the backplane and secure with its
locking screw.
Please note: Module pins 9 and 12 are linked on the backplane.
