This Quick Start Guide is designed to familiarize the user with the connection and configuration of the DTS 310 DIN rail
mounted single / 3 phase power & energy meter with kWh pulse output.
1. Supplied Items
Check that the meter and equipment matches your order specifications and has not been damaged during shipping. The following component(s)
are included in the package:
•The DTS 310 power meter.Check input ranges, output configuration and auxiliary power supply (if applicable) on the label of the unit.
For a more detailed explanation of the part number please download the latest version of the DTS 310 datasheet from:
https://www.measurlogic.com/product/dts-310/
•The necessary green connector plugs are fitted to the DTS meter.
2. Connecting the DTS 310
Wiring Voltage and Current Inputs
The DTS 310 accepts voltage inputs directly up to 480V or 600V 3 phase L-L (model dependent) or through PTs (potential transformers) for higher
voltages. Three phase currents are measured via “safe” 333mV or Flewxible Rogowski CTs (current transformers). Connection of any other CT than
these outputs could cause damage to the instrument. If there are any questions please call Measurlogic before powering up the unit.
Please refer to Application/Connection Examples for information on wiring conventions.
Input wiring terminals are clearly indicated and located on the upper side of the DTS 310 label. The Current and Voltage terminal strips are
pluggable to allow easy replacement of the DTS 310, if required. Removing the terminal strips should only be done once power has been removed
from the DTS 310. Input wiring terminals accept 2.5 mm2(12 awg) wire. The wires are connected by means of screw terminals that clamp down
onto the input wires. The voltage/PT inputs require fuses, not included, (see diagrams below) and should be rated at 1A 600Vac. Measurlogic can
provide an in-line fuse kit as an option if required.
Wiring Optional Auxiliary Power Input (AUX)
The DTS 310 operates normally when power is applied to Phase A, Phase B and/or Neutral depending on model number so no additional auxiliary
power supply is needed. To provide added flexibility to the DTS 310 meter it can be powered from a DC auxiliary supply (model dependant) in the
following ranges. (Fuses not included with meter but are offered as an option). See the rating label of the unit for more information.
•12 Vdc OR 24 Vdc OR 48 Vdc
Note: It is important to pay attention to the polarity when using a DC power supply. See label above for a reference to the polarity. Incorrect
connection will damage the DTS 310.
The following connection diagrams depict some examples of typical applications.
Other connection configurations are possible. (Consult Measurlogic)

Wiring the Digital Pulse Output
When ordered as an kWh energy pulse meter, the DTS 310 has a single digital output that functions as a pulse corresponding to measured kWh.
Digital Inputs (Marked 1, 2)
•Unused –do not connect.
Digital Output (Marked 3)
•The digital output is a potential-free N.O. (Normally Open) solid state relay output.
•The maximum switching voltage is 50Vdc and the maximum switching current is 100mA.
•The relay closure pulse width is 100ms. This minimum time between any two pulses is 100ms.
•The pulse rate is fixed at 1 pulse per kWh.
Switch Settings for the Current Sensor Type and Rating
The DTS 310 energy pulse meter has an 8-way DIP switch situated next to the pluggable 6-way I/O terminal that allows the user to configure
current sensor type, sensitivity and the primary rating.
ATTENTION
•The DTS 310 will be shipped with all the switches in the “OFF”position.
•The DTS 310 switches MUST be setup by the user to match the attached CTs.
The DTS 310-xx-NN-P-x meter is compatible with the following current sensors:
•333mV Output CTs –This type of current sensors is internally burdened so that the voltage output is 333mV for the current rating that
is specified on the CT itself. The current rating of the CT must be specified when ordering and cannot be changed in the field. The
switches [SW.1..SW.3] on the DTS meter must be set for “333mV CT” and the current switches [SW.4 .. SW.8] must correspond with the
Rated Current of the CT.
•Rogowski Coil CTs –This is a flexible CT. The sensitivity of this type of current sensor is specified in milli-volts (mV) per 1000A at
60Hz. Different models of Rogowski Coils have different sensitivities, which must be selected from the tables and the switches
[SW.1..SW.3] set accordingly. The CR Rating that is set on the switches does not affect the current measurement values. We
recommend that you set the CT Rating swiches [SW.4 .. SW.8] be set to the panel rating or the expected nominal current being
measured.
ATTENTION
If multiple CTs per phase are required, please consult our document
“Using Multiple CT Sets with DTS Meters” in the “Technical” section of the DTS 310 webpage
at https://www.measurlogic.com/product/dts-310/
“1” & “2” are
