2.2 Safety Guidelines
WARNING
The following installation instructions are intended for qualified personnel only. To avoid
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 310 can be hazardous.
Follow all applicable local and national electric codes.
Verify input voltage and current are within thresholds for the specific DTS 310 model. (See Product
Specification on page 4)
Use only UL or ETL listed current transformers.
ONLY USE CURRENT TRANSFORMERS WITH OUTPUTS THAT ARE COMPATIBLE WITH THE
MODEL OF DTS 310 (SEE SECTION 1.3.1). THE USE OF ANY OTHER CURRENT
TRANSFORMER CAN RESULT IN PERMANENT DAMAGE TO THE DTS 310.
Avoid any electrostatic discharge prior to working on the DTS 310 by first touching a grounded
structure prior to handling the DTS 310.
Before applying power make sure that all current transformer and voltage connections are securely
connected to the input terminals of the DTS 310.
If the DTS 310 is installed incorrectly any built in safety features may no longer be functional.
Before handling the DTS 310 ensure that all power running to the DTS 310 is removed.
The DTS 310 is for indoor use only, and MUST be mounted in a NEC compliant enclosure suitable for
the environmental conditions and locked with a user supplied lock.

2.3 Product Dimensions
2.4 Mounting Requirements and Guidelines
ATTENTION
Make sure to follow the following mounting requirements
and guidelines when mounting the DTS 310.
When mounting the DTS 310 make sure to follow these guidelines:
Mount the DTS 310 as close as possible to the electrical panel being monitored.
Make sure that there is at least 4” of clearance above and below the DTS 310 for wiring and
connector clearance and ¼” of clearance on both sides for cooling.
Position the DTS 310 such that the labeling can be read from the upright position.
Only UL or ETL rated conduits and glands should be used.
It is recommended that two separate conduits be run for voltage and current connections.
User Supplied UL or ETL certified 2A fast-blow fuses need to be installed between the Voltage
inputs of the DTS 310 and panel being monitored. Recommended Littelfuse BLS002 or equivalent.
14 to 12 AWG wire should be used for the voltage and ground with 300V or 600V insulation
depending on installation type and according to the table below.
A UL or ETL certified 600V circuit-breaker or fused disconnect must be installed within easy reach of
the DTS 310. The circuit-breaker or fused disconnect must be clearly marked as being “the
disconnecting device” for the DTS 310. See table below for the breaker and wire gauge to use.

3.2 Connecting Multiple Loads
The DTS 310 allows for ease and flexibility when monitoring multiple branches. The DTS 310 allows multiple CT
sensors to be connected in parallel via the green pluggable screw terminal.
When using parallel CT sensors, the following guidelines must be followed to ensure accurat e measuring.
All CT sensors must have a 333mV output.
All CT sensors must be of the same manufacturer/model number and current rating.
A full set of CT sensors must be used for each load.
The pair of wires from the CT sensor to the green pluggable scre w terminal must be twisted.
All CT sensors must be terminated at the green pluggable screw terminal .
A maximum of 3 loads can be monitored at once (Contact Measurlogic if more than 3 loads must be
monitored).
The measured phase current will be the total current across all the loads on that phase.
The CT primary rating for the DTS 310 must be set to the CT rating * Number of CT sets.
The example below shows how to calculate the service current for figure 3.2.1.

3.3 DC Auxiliary Power
The most common way to power the DTS 310 meter is through the voltage connections. If this situation is not
ideal the DTS 310 meter can be powered through a user supplied DC source.
ATTENTION
Check the DTS 310 model number for the correct DC
voltage to power the DTS 310 through the auxiliary.
WARNING
Make sure that all power is removed from the DTS 310 prior to wiring the DC auxiliary
