Operating voltage range
Minimum operating voltage
Vibration Severity level
The acceleration, speed and displacement of the E-
ECU mount must conform to the requirements
shown to the right in an overall range of 5 - 1000 Hz.
Waterproofness (of connector)
Precautions:
• IInstall the E-ECU in a location that is not subject to steam or high-pressure water for cleaning.
• Install the E-ECU in a location that is well ventilated and not subject to direct sunlight.
• Install the E-ECU so that the connector faces downward. Failure to do so may trap water in the connector,
resulting in corrosion of connector pins.
• Do not plug or unplug the connector for at least 6 seconds after the E-ECU is turned on or off.
• Do not touch connector pins with bare hands. Doing so may corrode or statically charge connector pins,
resulting in damage to electronic components in the E-ECU.
• Do not force a measuring or testing probe into the female coupler of the connector. Doing so may cause
contact failure of connector pins, resulting in malfunction of the E-ECU.
• Ensure no water is trapped inside the coupler when plugging or unplugging the connector. Water inside
the coupler may corrode connector pins, resulting in malfunction of the E-ECU.
• Avoid plugging/unplugging the connector more than ten times. Repeated plugging/unplugging may
cause contact failure of connector pins, resulting in malfunction of the E-ECU.
• Do not use the E-ECU that has suffered drop impact.
• When the machine is used in areas where a cryoprotectant/salt is distributed or near the seashore, the
aluminum case of the E-ECU may corrode, resulting in malfunction of the E-ECU. Use a cover to protect
the E-ECU against salt intrusion.
