POINTS OF CAUTION
■
NONINCENDIVE APPROVAL OPTION
• This equipment is suitable for use in Class I, Div. 2, Groups
A, B, C and D or Non-Hazardous Locations only.
• WARNING! Before You Remove the Unit from Its Base
Socket or Mount It, Turn Off the Power Supply and Input
Signal for Safety.
• WARNING! – Explosion Hazard –
Substitution of Components May Impair Suitability for
Class I, Div. 2.
• WARNING! – Explosion Hazard –
Do Not Disconnect Equipment Unless Power Has Been
Switched Off or The Area is Known To Be Non-Hazardous.
• The equipment was evaluated for use in the ambient tem-
perature and relative humidity as mentioned in ‘ENVI-
RONMENT’ section.
• The input and output wiring must be in accordance with
Class I, Div. 2 wiring methods and in accordance with the
authority having jurisdiction for use in these hazardous
locations.
■
CONFORMITY WITH EC DIRECTIVES OR UL
• This equipment is suitable for use in a Pollution Degree
2 environment and in Installation Category II, with the
maximum operating voltage of 300V.
Basic insulation is maintained between signal input and
output. Prior to installation, check that the insulation
class of this unit satisfies the system requirements.
• Altitude up to 2000 meters
• The equipment must be mounted inside a panel.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE/UL requirements. Failure to observe these re-
quirements may invalidate the CE/UL conformance.

POWER INPUT RATING & OPERATIONAL RANGE
Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V and 85 – 264V AC rating: 85 – 264V
(90 – 264V for UL), 47 – 66 Hz, approx. 4 – 6VA
24V DC rating: 24V ±10%, approx. 3W
11 – 27V DC rating: 11 – 27V, approx. 3W
110V DC rating: 85 – 150V (110V ±10% for UL), approx. 3W
■
GENERAL PRECAUTIONS
Before you remove the unit from its base socket or mount it,
turn off the power supply and input signal for safety.
■
ENVIRONMENT
• Indoor use
• When heavy dust or metal particles are present in the air,
install the unit inside proper housing with sufficient ven-
tilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
• Be sure that the ventilation slits are not covered with ca-
bles, etc.
■
WIRING
• Do not install cables (power supply, input and output)
close to noise sources (relay drive cable, high frequency
line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
■
AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.
• With voltage output, do not leave the output terminals
shortcircuited for a long time. The unit is designed to en-
dure it without breakdown, however, it may shorten ap-
propriate life duration.
• The M2VF2’s temperature coefficient equals 0.02%/°C
(0.01%/°F) except it may be off the standard when the unit
is subjected to strong air current (e.g. close to ventilation
device).
The output variation is proportionally wide to the output
span. It varies more with output ranges such as ±10V.
