Chapter 3 INSTALLATION & WIRING
Notes
• When controlling an electronic lock with the
N-8050DS/8540DS/8640DS unit, use "Torx" screws to
attach the unit at installation so that it cannot be detached
easily.
• For the N-8640DS installation, be sure to ground the rear-
mounted frame ground terminal ( p. 3-80 ).
• When installing the unit outdoors or at locations where
it gets wet with water, tightly seal the edges of the panel
and those of the box's rear surface in contact with the wall
surface. Besides, make a weep hole (to allow water to
exit) in the YS-13A's bottom.
• When installing the N-8050DS/8540DS under difficult
environmental conditions such as in coastal areas or at
humid locations, cover the inside of the N-8050DS/8540DS
with coating. For the coating method, consult your TOA
dealer.
• Treat unused cables so as not to short-circuit. (N-8640DS
only)
