The default mode of 700P relay contacts as shipped in this package is
normally open (N.O.). You must convert the contacts to the normally
closed (N.C.) mode. To do this, remove each of the relay cartridges
and flip the screw terminals to the N.C. position as follows:
1. Remove the coverplate by unscrewing the two captive screws.
2. Remove the red crossbar by unscrewing its captive screw.
3. Remove each relay cartridge from the housing by inserting a
screwdriver blade under a screw-terminal pressure plate and
prying out the cartridge.
4. On the relay cartridge, locate the screw terminals and corresponding
contact–mode symbols –| |– for N.O. and –|/|– for N.C.
5. To convert the contacts from N.O. to N.C. mode:
A. Unscrew the screw terminals 2 turns.
B. Flip each of the screw terminals from the –| |– (N.O.) position
to the –|/|– (N.C.) position.
6. Insert the relay cartridges into the case so the screw terminals
(now in the N.C. position) face front and are accessible.
7. Reassemble the red crossbar and coverplate, and securely tighten
the captive screws.
For additional information, refer to the Instruction Sheet that
accompanied the 700P relay.
