● EMC Conformity Standards
EN 301 489-1, EN 301 489-17, EN 61326-1 Class A, Table 2 (For use in industrial locations),
EN 55011 Class A, Group 1, EN 61000-6-2
CAUTION
This instrument is a Class A product, and it is designed for use in the industrial environment.
Please use this instrument in the industrial environment only.
● Safety Conformity Standards
Applicable standard: EN 61010-1, EN 62311
(1) Pollution Degree 2
“Pollution degree” describes the degree to which a solid, liquid, or gas which deteriorates
dielectric strength or surface resistivity is adhering. “2” applies to normal indoor atmosphere.
Normally, only non-conductive pollution occurs. Occasionally, however, temporary conduc-
tivity caused by condensation must be expected.
(2) Installation Category I
“Overvoltage category (Installation category)” describes a number which denes a transient
overvoltage condition. It implies the regulation for impulse withstand voltage.
“I” applies to electrical equipment which is supplied from the circuit when appropriate tran-
sient overvoltage control means (interface) are provided.
● Spectrum Conformity Standard
EN 300 328
l FCC compliance
This device complies with Part 15 pf FCC Riles. Operation is subject to the following two condi-
tions: (1) this device may not cause interference, and (2) this device must accept any interfer-
ence, including interference that may cause undesired operation of this device.
Co-located:
This transmitter must not be co-located or operated in conjunction with any other antenna or
transmitter.
FCC WARNING:
Changes or modications not expressly approved by the party responsible for compliance could
void the use’s authority to operate the equipment.

NOTE
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may cause harmful interferences to radio com-
munications. Operation of this equipment in a residential area is likely to cause harmful interfer-
ence in which case the user will be required to correct the interference at his own expense.
l Industry Canada (IC) compliance
This Class A digital apparatus complies with Canadian ICES-003.
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is sub-
ject to the following two conditions: (1) this device may not cause interference, and (2) this device
must accept any interference, including interference that may cause undesired operation of the
device.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of
a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce
potential radio interference to other users, the antenna type and its gain should be so chosen that
the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful
communication.
This radio transmitter IC Number 8999A-WIC001 has been approved by Industry Canada to
operate with the antenna types listed below with the maximum permissible gain and required an-
tenna impedance for each antenna type indicated. Antenna types not included in this list, having
a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with
this device.
Antenna type: Gain:
COLLINEAR 9dBi, 50Ω
Sleeve 2.14dBi, 50Ω
French:
Cet appareil numérique de la classe A est conforme à la norme NMB-003 du Canada.
Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio
exempts de licence. L’exploitation est autorisée aux deux conditions suivantes : (1) l’appareil ne
doit pas produire de brouillage, et (2) l’utilisateur de l’appareil doit accepter tout brouillage radioé-
lectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement.
Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut fonction-
ner avec une antenne d’un type et d’un gain maximal (ou inférieur) approuvé pour l’émetteur par
Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l’intention
des autres utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la puissance
isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l’intensité nécessaire à l’établissement
d’une communication satisfaisante.
Le présent émetteur radio IC Number 8999A-WIC001 a été approuvé par Industrie Canada pour
fonctionner avec les types d’antenne énumérés ci-dessous et ayant un gain admissible maxi-
mal et l’impédance requise pour chaque type d’antenne. Les types d’antenne non inclus dans
cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour
l’exploitation de l’émetteur.

• Electrostatic charge may cause an explosion hazard. Avoid any actions that cause the gen-
eration of electrostatic charge, such as rubbing with a dry cloth on coating face of product
and the antenna.
• Take care not to generate mechanical sparking when access to the instrument and periph-
eral devices in hazardous area.

(3) Installation
WARNING
• The installation of the devices should be carried out by the engineers or other professional
personnel of the related expertise. The installation should not be carried out by operators or
other unprofessional personnel.
• The installation should be in accordance with IEC 60079-14 and local electrical code.
• YFGW710 should be installed in upright position.
• The equipment shall be installed in accordance with the user’s manual.
• The instrument modication or parts replacement by other than authorized representative of
Yokogawa Electric Corporation is prohibited and will void IECEx certicate.
• The thread type of the cable entries shall be conrmed according to the user’s manual.
• Screws of power supply terminals shall be tightened with specied torque values: 1.2N•m to
1.4N•m.
• Cable glands, adapters and/or blanking elements shall be of Ex “n”, Ex “e” or Ex “d” and
shall be installed so as to maintain the specied degree of protection (IP Code) of the equip-
ment.
• Keep the cap attached to the antenna connector (N type) until the installation of the antenna
or antenna cables to protect the inside of the connector from exposure of light. In case the
antenna or antenna cables are removed from the connector, the inside of the antenna con-
nector should be protected from exposure of light.
• The antenna and the surge arrester shall be a simple apparatus in accordance with IEC
60079-11. Li and Ci of the simple apparatus shall be negligible. Temperature class of them
shall be determined from Po = 20 mW.
• Cable parameters for the connection of the antenna and/or the surge arrester are:
Cc = 4 nF; Lc = 20 μH
• The equipment shall be earthed in accordance with IEC 60079-14, in order to maintain in-
trinsic safety. A cable lug or a similar device shall be used to maintain the secureness of the
connection to the equipment. Care should be taken to avoid multi-point earthing since the
equipment is not galvanically isolated from the power supply.
• YFGW710 does not have a power switch inside. Prepare an dedicated breaker for the exter-
nal power line to turn ON/OFF the device.
• Make sure that the breakers are installed in the power supply circuits located in non-hazard-
ous areas so that the power can be shutoff when abnormality occurs.
• Note a warning label worded
“DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE MAY BE PRESENT.”
“POTENTIAL ELECTROSTATIC CHARGING HAZARD – SEE INSTRUCTIONS.”
• Electrostatic charge may cause an explosion hazard. Avoid any actions that cause the gen-
eration of electrostatic charge, such as rubbing with a dry cloth on coating face of product
and antenna.
• Take care not to generate mechanical sparking when access to the instrument and periph-
eral devices in hazardous locations.
