tighten the screws (using a Phillips #2 screwdriver) to secure the controller
against the panel.
7. If there is difficulty with any of the mounting requirements, apply a bead of
caulk or silicone sealant behind the panel around the perimeter of the case
WIRING
535-PROF controllers are thoroughly tested, calibrated and “burned in” at the
factory, so the controller is ready to install. Before beginning, read this chapter
thoroughly and take great care in planning a system. A properly designed system
can help prevent problems such as electrical noise disturbances and dangerous
extreme conditions.
1. For improved electrical noise immunity, install the 535-PROF as far away
as possible from motors, relays and other similar noise generators.
2. Do not run low power (sensor input) lines in the same bundle as AC power
lines. Grouping these lines in the same bundle can create electrical noise
interference.
3. All wiring and fusing should conform to the National Electric Code and to
any locally applicable codes.
4. An excellent resource about good wiring practices is the IEEE Standard No.
518-1982 and is available from IEEE, Inc., 345 East 47th Street, New York,
NY 10017, (212) 705-7900.
Diagrams on the next three pages serve as guides for wiring different types of
process inputs. The shaded areas on the diagrams show which rear terminals
are used for that type of wiring.
CAUTION
!
The enclosure into which the 535-
PROF Controller is mounted must be
grounded.
WARNING
!
Terminal 9 must be grounded to avoid
potential shock hazard, and improved
noise immunity to your system.
WARNING
!
Avoid electrical shock. Do not connect
AC power wiring at the source
distribution panel until all wiring
connections are complete.
WARNING!
ELECTRIC SHOCK HAZARD!
Terminals 1 and 2 carry live power. DO
NOT touch these terminals when
power is on.
