4.4 Wiring the Voltage
WARNING
High voltages are present on voltage input connections screw terminals.
Risk of serious injury and/or electrical shock exists. Prior to performing
any wiring operations, review all contents of the user manual and de-
energize the MAINS power switch. Only qualified personnel should
perform installation wiring. Installation wiring must comply with all local
and national electrical codes.
1. The four position terminal block located at the bottom left corner of the main
power board, is labeled V1, V2, V3, VN (neutral). Connect the NEUTRAL wire to
the appropriate terminal block position.
Fig. 12. Meter MAINS Voltage Input Terminal.
NOTE: For 3-wire delta-type applications, DO NOT connect the NEUTRAL wire.
Remove the terminal block screw for this position.
a. To ensure a safe installation, the Din-Mon™ meter requires an external
switch mechanism, such as a circuit breaker or in-line fuse, be installed on
the Din-Mon™ meter MAINS input wiring. The switch mechanism must be
installed in close proximity to the meter and easily reachable for the operator.
This device must also be marked as the disconnecting device for the Din-
Mon™ meter. Install 1/2 Amp fast activation in-line fuses with the suitable
voltage rating for each conductor phase at the MAINS input to the meter. The
fuses must be labeled to indicate voltage and current rating as well as ele-
ment characteristics. The fuse element must be a fast activating type, such
as the Littelfuse part number OKLK.500T (not included).
b. Connect the three AC main power wires (Phases A, B and C) to their respec-
tive positions on the 4-position terminal block and torque to 7 in-lb. Wiring
should be a minimum of #14 AWG, stranded, with 600V insulation rating.
After all conductors are connected to each of their respective terminal block
positions and tightened down, verify that each terminal block screw is
securely fastened by gently tugging on each conductor.
Verify that no conductor wires are frayed or shorting to adjacent terminal
block positions.

4.4.1 Phasing of Line Voltage
The 3-phase AC power input must be in proper phase sequence. If the sequence is
incorrect or a phase is missing, there will be a message on the meter’s display: “PH
Seq Err” or “PH Loss x” where ‘x’ is the missing phase. (Refer to the section on Line
Voltage Diagnostics if this message is present.) When the line voltage is connected
correctly, the error message will not be present.
Wait for the meter display to scroll to the voltage display. Verify that the meter reads
correct voltages on all phases.
Once the meter displays the correct line voltages and there are no error messages,
you are ready to connect the current sensors to the meter. Before continuing with the
installation, verify that the six screens display as follows:
Screen 1 (kWh): Should read 0.0 kWh.
Screen 2 (kW Peak Demand): kW peak should read 0.0 kW. There will not be a
date/time stamp yet.
Screen 3 (Load/Date and Time): Should read 0.0 kW load.
Screen 4 (Amps per Phase): There should be 0.0 on all three phases.
Screen 5 (AC Volts, L-N):
Screen 6 (AC Volts, L-L):
Screen 7 (Power Factor): There should be 0.0 PF on all three phases.
NOTE: The meter kWh and/or kW peak demand readings can be reset later.

The Din-MonTM meter is available for use with voltage (0.333V) output type of sensors
or with current (100mA) output type of sensors.
NOTE: The sensor output type is indicated in the part number (OS) as “V3” for
0.333V and “C1” for 100mA type.
Each output type is available in two forms:
1. Split-core current sensor. This sensor opens so that it can be attached around
the circuit being monitored without disconnecting the conductors.
2. Solid-core current sensor. This sensor does not open and requires the monitored
conductor to be removed from the circuit to install the current sensor.
NOTE: UL Current Sensors rated for Measurement Category III providing dou-
ble insulation for 600V installations.
