be disconnected beforehand!
Never work on cables carrying a live current!
Never use cables or connectors that are visibly damaged or known to be defective! Faulty, defective, or
improperly connected shielding, connectors, or cables present a risk of injury or death due to electric
shock and may also constitute a fire hazard!
Before operating the device, check that all cables are in good order. Ensure in particular that the cables
are undamaged (for example, kinks), that they are not wound too tightly around corners, and that no
objects are placed on the cables.
Cables must be laid in such a way that they do not present a tripping hazard.
The power supply should be connected using a short, low-inductance cable. Avoid the use of power
strips or extension cables if possible. If the use of such a device is unavoidable, ensure that it is
expressly rated for the rated currents of all connected devices.
Never connect or disconnect power, data, or signal cables during a thunderstorm! Doing so presents
a risk of injury or death, as cables and connectors may conduct very high voltages in the event of a
lightning strike!
The device cables must be connected or disconnected in the order specified in the user documentation
for the device. Connect all cables only while the device is de-energized before you connect the power
supply.
Always pull cable connectors out at both ends before performing work on connectors! Improperly
connecting or disconnecting this Meinberg system may result in electric shock, possibly resulting in

5 Important Product Information
5.4 Maintenance and Modifications
Important!
Before performing any maintenance work on or authorized modification to your Meinberg system (such
as installing or removing a power module), we recommend making a backup of any stored configuration
data (e.g., to a USB flash drive from the Web Interface).
5.4.1 Replacing the Battery
Your device’s receiver module is fitted with a lithium battery (type CR2032) that is responsible for the local
storage of almanac data and for the ongoing operation of the real-time clock (RTC) in the reference clock.
This battery has a life of at least ten years. However, if the device develops the following unexpected be-
haviors, the voltage of the battery may have dropped below 3 V, and the battery needs to be replaced as a
result:
•The reference clock has the wrong date or wrong date when the system is started.
•The reference clock repeatedly starts in Cold Boot mode (i.e., it keeps needing to find the satellites in
view from scratch, resulting in the synchronization process taking a very long time)
•Some configuration options relating to the reference clock are lost every time the system is restarted.
In this case you should not replace the battery on your own. Please contact the Meinberg Technical Support
team, you will provide you with precise guidance on how to perform the replacement.
LANTIME Date: February 1, 2023 13

5.5 Prevention of ESD Damage
An ESDS device (electrostatic discharge-sensitive device) is any device at risk of dam-
age or malfunction due to electrostatic discharge (ESD) and thus requires special mea-
sures to prevent such damage or malfunction. Systems and modules with ESDS devices
usually bear this symbol.
Precautionary measures should be taken to protect ESDS components from damage and malfunction.
•Before removing or installing ESDS components, ground your body first (for example, by touching a
grounded object) before touching ESDS modules.
•Ensure that you wear a grounding strap on your wrist when handling such ESDS components. These
straps must in turn be attached to an uncoated, non-conductive metal part of the system.
•Use only tools and equipment that are free of static electricity.
•Only touch or hold ESDS components by the edges. Never touch any pins or conductors on the ESDS
components.
•When removing or installing ESDS components, avoid coming into contact with persons who are not
grounded. Such contact may compromise your connection with the grounding conductor and thus also
compromise the ESDS component’s protection from any static charges you may be carrying.
•Always store ESDS components in ESD-proof ("antistatic") bags. These bags must not be damaged in
any way. ESD-proof bags that are crumpled or have holes cannot provide effective protection against
electrostatic discharges. ESD-proof bags must have a sufficient electrical resistance and must not be
made of conductive metals if the ESDS components has a lithium battery fitted on it.
