Low-power system I/O modules including the EN311 should be mounted at the left side
of the unit, and high-power system I/O modules should be mounted at the right side of
the unit. In cabling as well, low-power system cables and high-power system cables
should be separated. section 9.4, "Network Wiring", describes network cable wiring.
The EN311 draws 0.7 amperes from the S controller power supply (5 VDC). For details
on determining the power supply capacity, see the section about the power supply
capacity in the S3 User's Manual - Hardware.
Caution
• The EN311 is designed specially for the V Series model 3000 and should only be mounted
and used in a V Series model 3000 base unit. Do not use this module independently or
mounted in any other equipment. Such usage could result in electric shocks, personal injury,
or damage to the EN311 and other equipment.
• The EN311 itself should only be mounted or removed when all power is turned off. Similarly,
connections to the terminal block should only be made or removed when all power is turned
off. Not observing this precaution could result in electric shocks, malfunctions, or damage to
the EN311 or other equipment.
• Do not allow foreign objects such as wire shreds to get into the EN311. This could result in
fire, breakdown, or malfunction.
• Verify that connectors, cables, and the mounting of the EN311 itself in the base unit are all
secured with screws or stoppers and that there is no dropout or loose screws in any of these
parts.
If any of these parts is inadequately secured, breakdown or malfunction could
occur as the result of vibration.
