Overview
The MiniPowermonitor (1405-M610) measures and displays voltage
and current parameters of low voltage AC power systems:
• Line-to-neutral and line-to-line voltages
• Instantaneous currents
• 15-minute averaged currents
• Peak currents

The MiniPowermonitor is a compact unit, with a 96 x 96 mm (3.78 x
3.78 in) front panel and a depth of only 65 mm (2.56 in).
The module’s display is arranged in 3 lines, each with 4 digits. The red
14 mm (0.55 in) high LED characters are easily readable from a
distance, in high ambient light conditions, and from acute viewing
angles. The measurement mode is indicated by 5 LED lamps that
show which parameter is displayed at that time.
Phase voltage and current measurements are made by sequential
scanning at 2 samples per second, so that 3 phase measurements are
made in 1.5 seconds. The updated average current value is displayed
approximately every 60 seconds, interjected into the cyclical sequence
of displayed parameters. Parameter values can be read out of
sequence, using the function (F) key on the front panel.

Installation
Only qualified personnel should install and wire this equipment. Refer
to the following safety guidelines prior to installation.
ATTENTION
ATTENTION
Only qualified personnel, following accepted safety
procedures, should install and wire the
MiniPowermonitor. Before beginning any work,
disconnect all sources of power and verify that they
are de-energized and locked out. Failure to follow
these instructions may result in personal injury or
death, property damage or economic loss.
Never open a current transformer (CT) secondary
circuit with primary current applied. Wiring between
the CTs and the MiniPowermonitor should include a
shorting terminal block in the CT secondary circuit.
Shorting the secondary with primary current present
allows other connections to be removed if needed.
An open CT secondary with primary current applied
produces a hazardous voltage, which can lead to
personal injury, death, property damage or economic
loss.
1. Install your MiniPowermonitor within a suitable enclosure. Make
sure the enclosure provides adequate clearance for ventilation
and wiring of the module.

2. Determine your wiring mode and install wiring between the
MiniPowermonitor and your power system.

3. Configure the current transformer (CT) ratios to match those
used in your power system connections.

Grounding
MiniPowermonitors do not need to be grounded because of the
isolated enclosures. Follow all local requirements for grounding of PT
and CT secondaries.

The module uses industry-standard current transformers with a 5A
secondary for line current measurement.
• Internal shunt resistance for 5A current transformers: 0.01 ohm.
Aux Supply: With this option, instrument power is supplied by a
separate 120V or 240V line, independent of the measured power lines.
A second connector block (2-pin, spring-clamp terminals type) is
added at the rear with this option.
TIP
Terminals 2 and 4 (counting from left to right) are
not used. No connections should be made to these
terminals.
A unit with the 120V supply option is not designed to operate on
240V or any other voltage. Likewise, a unit with the 240V supply
option is not designed to operate on 120V or any other voltage. Units
designed for 400V and 480V operation do not have an auxiliary
supply connection and receive power from the measurement line.
Ensure that each unit is properly supplied with a power source that
matches the voltage designation of your unit.

When the desired value is reached, the module is switched off without
pressing the function key any further. The ratio is now set and
protected against power interruptions. Now whenever the module is
switched on, this pre-set value is used for measuring line currents.
The ratio setting in existence when the power is switched off is the
same value that is valid when the power is switched on again, without
pressing the function key.
