Note 1:
Refer to MS5C06 for available signal cables of different
lengths, to connect from the shelf backplane rectifier
position to the remote sensing point.
Note 2:
Use a printed circuit or wire-wrap board to interface all
the 26-pin connector ribbons from all the shelves. All
RC- signal connections (pin 11, 6, 1) must be joined
together. All the RC+ connections (pin 20) must also be
joined together. For forced share current mode
applications, the force share signal (pin 16) must also be
interconnected between the shelves.
Note 3:
Use #20 AWG (105°C) wire.
Note 4:
Use 1.6A fuse A0384386 with ferrule type fuse
holder A0384387.
