Notes
• When controlling an electronic lock with the N-8050DS/8540DS unit, use
"Torx" screws to attach the unit at installation so that it cannot be detached
easily.
• For the N-8050DS installation, be sure to ground the electrical box.
For the N-8540DS installation, be sure to ground the electrical box or the
frame ground terminal on the unit's rear (
p. 3-30 ).
• When installing the N-8050DS/8540DS at outdoor or locations where it gets
wet with water, tightly seal the panel edges. Besides, provide a weep hole at
the underside of the mounting box to permit water to drain off.
• 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.
