IM 11M12D01-01E 3-10
3.3.1 Installation Location
Follow the guidelines below when selecting a location for the averaging converter.
(1) The touch screen display should be clearly visible and easily accessible for key
operation: the display at eye level is recommended.
(2) A wall or construction should be strong enough to support the weight of the
converter.
(3) The converter should be easily accessible for inspections and maintenance.
(4) The ambient temperature should be in the range of -5 to 50
ЊC and the temperature
variation should be small: the daily temperature range within 15
ЊC is recommended.
(5) The humidity should be in the range of 10 to 85%RH and no condensation may
occur.
(6) No corrosive gases are present.
(7) No dust exists.
(8) There is minimal vibration.
(9) The converter should be near the detectors: the two-way resistance between detector
and converter should not exceed 10
⍀.
DANGER
• The averaging converter is heavy. Take extra care not to accidentally drop it.
Installation work should be done by an adequate number of people.
CAUTION
The averaging converter is heavy (100/115 VAC version: approx. 13 kg, 230 VAC
version: approx. 25 kg) so needs to be installed on a wall or construction strong
enough to support.
3.3.2 Installation in an Instrument Panel
When installing the averaging converter in an instrument panel, operability,
maintainability, and environmental resistance should be considered.
(1) Installation Space and Relationship to Peripheral Devices
Follow the instructions below to determine the positions of the averaging converter and
peripheral devices.
• Do not place heat-generating devices in close proximity of the averaging converter:
specially, avoid a place under the averaging converter.
• Do not place power related devices such as transformers or electromagnetic switches
in close proximity of the averaging converter.
• Segregate wiring ducts for signal lines and those for power lines and do not place in
close proximity.
Figure 3.8 shows the requirements for the mounting holes for the averaging converter.
See Section 2.4 for the dimensions of the averaging converter and maintenance
clearance.
