I.S. values Power supply-eld device:
Po ≤ Pi, Uo ≤ Ui, Io ≤ Ii
Calculation of max. allowed cable length:
Ccable ≤ Co - ∑ci - ∑ci (Terminator)
Lcable ≤ Lo - ∑Li
Number of Devices
The number of devices (max. 32) possible on a
eldbus link depends on factors such as the power
consumption of each device, the type of cable used,
use of repeaters, etc.
B) ATEX Flameproof Type
Caution for ATEX ameproof type.

Note 3. Installation Instructions
• The cable glands and blanking elements
shall be certied in type of protection
ameproof enclosure “d” suitable for the
conditions of use and correctly installed.
• With the use of conduit entries a sealing
device shall be provided either in the
ameproof enclosure or immediately on the
entrance thereto.
• To maintain the degree of ingress protection
IP65 according to EN 60529 special care
must be taken to avoid water entering the
breathing and draining device when the valve
positioner is mounted with the feedback shaft
in the upright position.
Note 4. Operation
• Keep strictly the WARNING on the label on
the positioner.
AFTER DE-ENERGIZING, DELAY 5

USE HEAT-RESISTING CABLE & CABLE
GLAND ≥ 90°C.
Note 5. Maintenance and Repair
• The instrument modication or parts
replacement by other than authorized
representative of Yokogawa Electric
Corporation is prohibited and will void KEMA
Flameproof Certication.

Note 3. For the installation of this positioner, once
a particular declared type of protection
is selected, the other type of protection
cannot be used. The installation must be in
accordance with the description about type
of protection in this instruction manual.
Note 4. In order to avoid confusion, unnecessary
marking is crossed out on the label other
than the selected type of protection when
positioner is installed.

according to IEC 60529, special care must
be taken to avoid water.
Note 6. Maintenance and Repair
• The instrument modication or parts
replacement by other than authorized
representative of Yokogawa Electric
Corporation is prohibited and will void ATEX
