R (2) Connection arrangements (Ref. Fig. 009, 010)
 _______
CAUTION : BE CAREFUL WHEN YOU REMOVE RELAYS THAT HAVE THE WORD "SUPPRESSED" WRITTEN IN BLUE ON THE TOP OF THE HOUSING. YOU MUST REPLACE THEM WITH RELAYS OF THE SAME TYPE (THEY MUST ALSO HAVE THE WORD "SUPPRESSED" IN BLUE ON THE HOUSING). THERE IS A RISK OF DAMAGE TO EQUIPMENT IF YOU INSTALL A DIFFERENT TYPE OF RELAY.
R ____
NOTE : The word SUPPRESSED written in blue on the top of the relay R housing means that a suppressor is installed in the coil R circuitry.

4. Connection Procedure
 For correct connection between relays and relay bases, two mechanical systems of polarization are usually used:
 A. By polarization keys:
