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.
