Meter M40-D
Panel meter 96x48mm size for VDC and ADC
Panel meter for DC voltages and DC currents. Measure
category in CAT-III up to 300Vdc and CAT-II up to 600Vdc.
Currents up to 5Adc. Scalable reading.
Instrument with 96x48mm standard DIN size. Resolution 4
digits plus negative sign (“-9999”) or 5 digits with negative
sign with last digit xed to zero (“99990”, with menu function
“Right Zero”).
Management for up to 4 alarms with 1 or 2 setpoints each,
with hysteresis and delays. Provides memory for maximum
and minimum, left zeros, display on selectable steps, xed
digits, recursive display lter, password, brightness control,
“measure” function (visualizes input signal without scaling),
offset and signal high autocorrection (assigns the actual
signal to the low or high reading), “peak&hold” function and
password.
Power options with universal AC and DC ranges, and space
for three additional control and/or signal retransmission
modules.
For measurements in CAT-III (depends on the range selected) and for environments with pollution degree 1 and 2
without condensation. Standard IP54 front protection, with
optional upgrade to IP65 protection.
Connections via plug-in screw terminals and conguration
via three front push-buttons. For application on industrial
environments.
This instrument has been designed and veried according to the 61010-1
CE security regulation, and is designed for applications on industrial environments. See the “CE Declaration of Conformity” further in this document for
information on the category of measure and the degree of pollution levels
that apply.
Installation of this instrument must be performed by qualied personnel
only. This manual contains the appropriate information for the installation.
Using the instrument in ways not specied by the manufacturer may lead
to a reduction on the specied protection level. Disconnect the instrument
from power before starting any maintenance and / or installation action.
Risk of electrical shock. Instrument terminals can be connected
to dangerous voltage.
Instrument protected with double isolation. No earth connection
required.
The instrument does not have a general switch and will start operation as
soon as power is connected. The instrument does not have protection fuse,
the fuse must be added during installation.
The instrument is designed to be panel mounted. An appropriate ventilation
of the instrument must be assured. Do not expose the instrument to excess
of humidity. Maintain clean by using a humid rag and do NOT use abrasive
products such as alcohols, solvents, etc.
General recommendations for electrical installations apply, and for proper
functionality we recommend : if possible, install the instrument far from
electrical noise or magnetic eld generators such as power relays, electrical motors, speed variators, ... If possible, do not install along the same
conduits power cables (power, motor controllers, electrovalves, ...) together
with signal and/or control cables.
Before proceeding to the power connection, verify that the voltage level
available matches the power levels indicated in the label on the instrument.
In case of re, disconnect the instrument from the power line, re alarm
according to local rules, disconnect the air conditioning, attack re with
carbonic snow, never with water.
Instrument is in conformity with CE rules and regulations. See
“CE Declaration of Conformity” further in this document.

Earth connection - Although a terminal is offered for earth connection, the
connection is optional. The instrument does not need this connection for
correct functioning nor for compliance with the security regulations.
Fuse - To comply with security regulation 61010-1, add to the power line
a protection fuse acting as disconnection element, easily accessible to the
operator and identied as a protection device.
Power “H” fuse 250mA time-lag
Power “L” fuse 400mA time-lag
