( see note 1 )

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.
