Measurlogic DTS DC Quick Start Manual

This Quick Start Guide is designed to familiarize the user with the connection and configuration of the DTS DC DIN
rail mounted DC power & energy meter with RS-485 or TCP communications. These instructions are given using
the Windows OS.

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:
Quick Start Guide (DTS DC Application / Connection Examples in section 2)

DTS DC power monitor. 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 DC datasheet from

2. Connecting the DTS DC

Wiring Voltage and Current Inputs

The DTS DC is connected as a 3 wire configuration reducing the possibility of in-correct connections resulting in damage to the instrument. It
accepts a DC voltage input directly up to 800Vdc (model dependant). The current can be from a 50-100mV shunt or up to 10A direct
connection (model dependant). 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 DC label. The Current and Voltage terminal strip is
pluggable to allow easy replacement of the DTS DC, if required. Removing the terminal strip should only be done once power has been
removed from the DTS DC. Input wiring terminals accept 2.5 mm
clamp down onto the input wires. The voltage input requires fusing, not included, (see diagrams below) and should be rated at ≤ 1A. Please
check with local code requirements to ensure correct installation.

Wiring Auxiliary Power Input (AUX)

The DTS DC meter is powered from a DC auxiliary supply 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

Auxiliary power will not be needed for "self-powered" models

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 DC.
