Product Damage
Inserting or removing modules with power applied may result in damage to module
components.
Before installing or removing additional devices or modules, read the documentation that
came with the product.
Cabling and Connectors
Product Damage
RJ-45 connectors on modules are either twisted-pair Ethernet (TPE) or E1/T1/J1 network
interfaces. Connecting an E1/T1/J1 line to an Ethernet connector may damage your
system.
Make sure that TPE connectors near your working area are clearly marked as

network connectors.
Verify that the length of an electric cable connected to a TPE bushing does not

exceed 100 meters.
Make sure the TPE bushing of the system is connected only to safety extra low

voltage circuits (SELV circuits).
If in doubt, ask your system administrator.
Battery
Board/System Damage
Incorrect exchange of lithium batteries can result in a hazardous explosion.
When exchanging the on-board lithium battery, make sure that the new and the old battery
are exactly the same battery models.
If the respective battery model is not available, contact your local SMART EC sales
representative for the availability of alternative, officially approved battery models.
Data Loss
Exchanging the battery can result in loss of time settings. Backup power prevents the loss
of data during exchange.
Quickly replacing the battery may save time settings.
