CAUTION
DATA LOSS
If the microSD memory card is being written to and a voltage drop
occurs or the card is removed, data may be lost or the microSD
memory card may be ruined.
Insert the microSD card only when the easyE4 is de-energized.
Do not write to microSD cards constantly:
l
microSD cards have a limited number of write cycles.
l
If there is a voltage drop while a write operation is in progress,
data loss is highly likely to occur.
Remove the microSD card only when the easyE4 is de-energized.
Before switching off the device, make sure that there are no pro-
grams writing to the microSD card.
CAUTION
SHORT-CIRCUIT HAZARD
If the device is or has been exposed to environmental fluctuations
(ambient temperature, air humidity), condensation may form on or
inside it. As long as this condensation is present, there will be a short-
circuit hazard.
Do not switch on the device when it has condensation in or on it.
If the device has condensation in or on it, or if the panel has been
exposed to environmental fluctuations, let the panel settle into the
existing ambient temperature before switching it on. Do not expose the
device to direct thermal radiation from heating appliances.
CAUTION
UV LIGHT
Plastics will become brittle when exposed to UV light. This artificial
aging will reduce the easyE4 unit's lifespan. Protect the device from
direct sunlight and other sources of UV radiation.
