 Solder Eyelets (Ref. Fig. 006)

 (a) Connect the wire to the eyelet:
 -Engage the wire in the solder eyelet
 -Touch the solder eyelet with the hot tip of the soldering iron
 -Apply the solder on the solder eyelet
 -Let the solder melt
 -Remove the soldering iron and do not let the eyelet assembly move until it is cool
 (b) Examine the solder connection
 (Ref. Fig. 004)

 Hook Terminals (Ref. Fig. 007)

 (a) Connect the wire to the hook terminal:
 -Engage the hook terminal on the wire
 -Apply the solder on the hook terminal
 -Let the solder melt
 -Remove the soldering iron and do not let the hook terminal assembly move until it is cool.
 (b) Examine the solder connection.

 _________________________________________________STACKING OF TERMINALS - DESCRIPTION AND OPERATION
R  _______1. General 
R  This chapter describes the method to be applied to stack the terminals: 
R  - on the terminal block studs, 
R  - on the circuit breakers, 
R  - at the grounding points.
R  __________2. Main Rules 
R  - Avoid contact of the wires and/or the terminals with the environment 
R  (structure, insulators, etc...). 
R  - In general cases, maximum stacking of four terminals is authorized for 
R  each pole. In some specific cases, stacking of five terminals is accepted. 
R  - When terminals of different dimensions must be stacked, start by placing 
R  the larger one, then install the others in decreasing size. 
R
R  ____________________3. Terminal Orientation 
R  (Ref. Fig. 001) 
R  The wires must be installed depending on the adjacent environment and 
R  direction of the wiring: 
R  - When the wires come from opposite directions, the terminals must point in 
R  opposite directions. 
R  - When the wires come from the same direction, the terminals must point in 
R  the same direction. 
R  The terminals must be installed two-by-two and back-to-back. 
R  - At grounding points, the wires come from several directions and must be 
R  installed in a fan formation around the screw.
R  _____________________4. Stacking of Terminals 
R  Terminals must be stacked in different orders depending on the type and the 
R  number of terminals. 
R  - Two-terminal installation 
R  Case of two copper terminals 
R  (Ref. Fig. 002) 
R  Case of one copper + one aluminum terminal: 
R  (Ref. Fig. 002) 
R  - install aluminum terminal, 
R  - install copper terminal, 
R  - Three-terminal installation 
R  Case of one copper + two aluminum terminals: 
R  (Ref. Fig. 002) 
R  - install aluminum terminal, 
R  - install copper terminal, 
R  - install aluminum terminal. 
R  Case of one aluminum + two copper terminals: 
R  (Ref. Fig. 002)
