Page 6: Installation
• 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. -
Page 7: Product Dimensions
• 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. -
Page 8: General Mounting Requirements And Guidelines
• DTS 307 meters that have an “A” in the Service Type field of the model number (as shown in section 1.3.2) are powered through the 24Vac/dc auxiliary terminals. An external IEC 60950 compliant Class 2 isolated power supply and associated wiring methods must be used for this powering option only. - Page 9 A UL or ETL certified 600V circuit-breaker must be installed as a disconnecting device for the DTS 307 and must be positioned within easy reach of the DTS 307. The circuit-breaker employed for this disconnecting device shall meet the relevant requirements of IEC 60947-1 and IEC 60947-3, be suitable for the application, and MUST be clearly marked as being “the disconnecting device”...

Rogowski Coil CTs (with an external integrator) – Measurlogic DTS meters can accept Rogowski Coil CTs directly connected to the DTS 307 meter, so an external integrator module is NOT required. However, if the system already has an external integrator module installed, then the output of the integrator will be 333mV for the current specified on the integrator label. - Page 15 Medium or High Voltage Applications (with external PTs): The Voltage(L-L) Primary and Secondary settings MUST be set according to the primary and secondary ratings of the external PTs. 7268 S.
