special configuration communication cable to
interface the SCC unit and personal computer
together. (See Requirements - on reverse side for
purchasing information.)
Instructions on how to accomplish configuration
change are included with SC Configuration Utility
and not covered here.

INSTALLATION AND SAFETY GUIDANCE NOTES
Environment - Dwyer Instruments, Inc. products are designed to operate reliably and
safely in their specified environment. However the following guidelines must be followed to
ensure Safety, Electromagnetic Compatibility and Performance.
• Products have been tested for the Industrial Environment (BS EN 50081-2 and 50082-
2) unless otherwise stated. Operation in any other environment is not guaranteed and
at the risk of the User.
• The User is required to suppress high energy transients, such as those caused by
lightning strikes, unless the product is specified for such purposes. Non-resistive loads
and contact arcing must be suppressed at source.
• Products are intended for installation inside an equipment cabinet or suitable enclosure
unless otherwise specified. This should be accessible only to qualified personnel during
commissioning and maintenance. Open chassis products for use above 50V should only
be accessible by the removal of a cover using a key or tool.
• Anti-static precautions and conventional Instrumentation best practice must always be
observed. Each active module should be protected by a suitably rated fuse or equivalent
protection device.
Product EMC Performance - The performance of Dwyer Instruments, Inc. products
that fall within the scope of the EMC directive will meet the requirements of the relevant
performance criteria as determined by the particular tests listed in the EMC standards.
Products may temporarily be affected by the application of some electromagnetic distur-
bances but will return to published specification thereafter. Individual product details on
request.
Directives - Dwyer Instruments, Inc. products are intended for installation by qualified
personnel into a larger piece of equipment or system and are not accessible by the operator
or that equipment or system under normal use. They do not contain any moving parts as
defined by the Machinery Directive and do not fall within the scope of either the Machinery
Directive or the Low Voltage Directive unless other stated. The responsibility for the final
equipment or system lies with the builder of that equipment or system. It is the duty of
the system designer or installation engineer to ensure that our products are used in
accordance with our instructions and that current safety, wiring and other relevant regula-
tions are followed.

Warning: This unit is protected against
abnormally high and low voltages. Marginally
low voltages, marginally high voltages and
power fluctuations for extended periods of time
can cause permanent damage.
Caution: When installing the unit’s wir-
ing do not over-tighten the wiring terminal set
screws. Turn set screw until wire’s resistance
is encountered and wire is securely captured.
Over tightening will cause damage to the unit.
Recommended torque: 1.0 in/lbs
