Safety Guidelines
WARNING
The following installation instructions are intended for qualified personnel only. To
reduce the risk of electrical shock and personal injury, do not perform additional tasks not
stated in this procedure unless you are qualified to do so.
Always adhere to the following safety guidelines:
•
Only qualified personnel or
licensed electricians
should handle the installation. Input voltages to
the DTS 307 can be hazardous.
•
Follow all applicable local and national electric codes.
•
Verify input voltage and current are within thresholds for the specific DTS 307 model. (See Product
Specification on page 5)
•
Only Current Transformers that are listed to UL 2808 for use in 250Vac or 600Vac line-
to-line circuits (as appropriate for the installation) may be used with this meter.
•
ONLY USE CURRENT TRANSFORMERS WITH OUTPUTS THAT ARE COMPATIBLE WITH THE
MODEL OF DTS 307 (SEE SECTION 1.3.1). THE USE OF ANY OTHER CURRENT
TRANSFORMER CAN RESULT IN PERMANENT DAMAGE TO THE DTS 307.
•
Avoid any electrostatic discharge prior to working on the DTS 307 by first touching a grounded
structure prior to handling the DTS 307.
•
Before applying power make sure that all current transformer and voltage connections are securely
connected to the input terminals of the DTS 307.
•
If the DTS 307 is installed incorrectly any built-in safety features may no longer be functional.
•
Before handling the DTS 307 ensure that all power running to the DTS 307 is removed.
•
The DTS 307 MUST be mounted in a NEC compliant enclosure suitable for the application
’
s
environmental conditions.
•
The DTS 307 may be used outdoors if housed in an outdoor rated enclosure that prevents water
ingress, such as a NEMA Type 3R / IP14 or higher that is suitably rated for the application.
•
The enclosure must be equipped with a
user supplied lock
or other means to prevent unauthorized
access.
