2.2 Prevention of ESD Damage
ATTENTION!
The designation ESD (Electrostatic Sensitive Devices) refers to measures which are used
to protect electrostatically endangered components from electrostatic discharge and thus
to prevent destruction. Systems and assemblies with electrostatically endangered components
usually have the following characteristics:
Indicator for assemblies with electrostatic endangered components
The following measures protect electrostatically endangered components from destruction:
Prepare removal and installation of assemblies
Unload yourself (for example, by touching a grounded object) before touching assemblies.
Ensure that you wear a grounding strap on the wrist when working with such assemblies, which
you attach to an unpainted, non-conductive metal part of the system.
Use only tools and devices that are free from static electricity.
Transporting Assemblies
Assemblies may only be touched at the edge. Do not touch any pins or conductors on assemblies.
Installing and Removing Assemblies
Do not touch persons who are not grounded while removing or installing components. This could
result in a loss of grounding protection from your electrostatic discharge.
Storing Assemblies
Always keep assemblies in ESD protective covers. These protective covers must be undamaged.
ESD protective covers, which are extremely wrinkled or even have holes, no longer protect against
electrostatic discharge.
ESD protective covers must not be low-resistance and metallically conductive if a lithium battery
is installed on the assembly.

2 Important Safety Hints
2.3 Supply Voltage
WARNING!
The IMS system in which the module is used operates at a dangerous voltage. The specific safety instruc-
tions can be found in the manual of the respective IMS System.
If the module is a hot-pluggable power supply unit, disconnect its power cable before removing it from the
IMS System.
Never open a power supply unit cause dangerous voltages can even exist after it has been disconnected from
the electrical supply. If a power supply is not working anymore, e.g. due to a defect, please send it back to
Meinberg for necessary repairs.
Non-observance of these safety instructions can cause serious personal injury and material damage. Installation,
initial start-up and operation of the IMS System may only be performed by qualified technical experts.
2.4 Cabling
WARNING!
DANGER TO LIFE BY ELECTRICAL SHOCK! NO LIVE WORKING!
Wiring or any other work done the connectors particularly when connectors are opened may never be carried out
when the installation is energized. All connectors must be covered to prevent from accidental contact to life parts.
ALWAYS ENSURE A PROPER INSTALLATION!

3 Replacement or Installation of a Hot-pluggable
IMS Module
If the system is supplied with an antenna and antenna cable, it is advisable to first mount the antenna in a
suitable location (see chapter Antenna Mounting) and lay the antenna cable.
Please use a Torx screwdriver (T8 x 60) for removal and installation of the module.
1. Follow the safety instructions at the beginning
of this manual!
2. Remove the two marked Torx screws from the
module holder plate or the cover plate of
the empty slot.
3. Note when removing!
Pull the module carefully out of the guide
rail. Note that the module is firmly anchored
in the connector block of the housing. You need
a certain amount of force to release the module
from this link. Once the connection to the
connector block of the system’s backplane is
loosened, the module can be easily pulled out.
4. Note during installation!
Please ensure that the module is correctly inserted into the
two guide rails of the system housing as otherwise damage to the module and the housing could be caused.
Make sure that the module is securely locked into the connector block before you fasten the two screws.
5. Now you can put the installed module into operation.

3 Replacement or Installation of a Hot-pluggable IMS Module
3.1 Important Hints for hot-pluggable IMS Modules
The following points should be strictly observed when replacing IMS modules during operation. Not all IMS
modules are fully hot-pluggable. Of course, it is not possible to replace a power supply unit of a non-redundant
system without first having installed a second power source in operational mode.
The following applies to the individual IMS slots:
PWR: "hot swappable" If you operate your system with only one
power supply, a second power supply must
be installed before removing/replacing it
to keep your system functioning.
I/O, ESI and MRI Slots: "hot swappable".
CLK1, CLK2: "hot swappable" Afer the exchange or the installation of a
clock module a rescan of the reference clocks
(Rescan Refclocks) must be executed in the web
interface menu "System".
CPU: "hot swappable" The NTP service and access to the web interface
are interrupted while the CPU is disconnected.
Also the management and monitoring functions are
no longer available.
RSC/SPT: "hot swappable" The switching function or the distribution of
generated signals is interrupted while the RSC/SPT
is disconnected.

4 FDM - Frequency Deviation Monitoring
The module FDM180 was designed to calculate and
monitor the frequency and its deviation in 50/60Hz
power line networks.
A preconnected reference is necessary that provides a
serial time string and a PPS (pulse per second). The
accuracy of the measurements is derived from these
signals. The module calculates the frequency as well
as the time, based on the mains frequency. The time
deviation (TD) is the difference of this calculated time
(PLT) to the reference time (REF). This time deviation
as well as the frequency itself is sent out via serial
interface or is beeing converted to an analog voltage
output provided by a DAC.

Automatic Monitoring of Powerline Frequency
It is possible to define an upper and lower limit for the powerline frequency and receive alarm messages (email,
syslog, SNMP traps) when a LANTIME device detects that the frequency measurement value is outside the
acceptable range.
With the FDM configuration menu the following parameters can be set:
Line Frequency: configure frequency of the observed power line
Min Frequency: an error occurs if the frequency reaches the min constraint
Max Frequency: an error occurs if the frequency reaches the max constraint
Max Negative Time Deviation: an error occurs if the frequency reaches the max negative constraint
Max Positive Time Deviation: an error occurs if the frequency reaches the max positive constraint
Timezone: used local timezone for reference time and powerline time
Activate Logging: activate logging for FDM in XtraStats
Reset FDM to restart the device

4 FDM - Frequency Deviation Monitoring
Analog Outputs
Depending on the features of your system, the FDM180 provides two analog outputs (A1/A2). These out-
puts have a voltage range of -2.5V ... + 2.5V, divided into 65,536 steps (16-bit resolution).
Either the frequency deviation or the difference time of each analog output can be selected as display-value.
Mode:
Time Deviation: Depends on the defined constraints for Min Time Deviation and Max Time Deviation
Example: min:-100s and max:+100s if the time deviaton reach -100s the analog output
is at -2.5 V and if +100s then at +2.5 V with a resolution of 16bit DAC
Frequency Deviation: Depends on the defined constraints for Min Frequency Deviation and
Max Frequency Deviation
Example: min: 45Hz and max: 55Hz @ 50Hz line frequency if the frequency deviation
reach 45Hz the analog output is at -2.5 V and if 55Hz then at +2.5V with a resolution
of 16bit DAC
IMS-FDM Setup Guide Date: 4th November 2020 13

Submenu Set TDEV
Time Deviation set a value to preconfigure the time deviation 0 for reset
(example: if you already had one FDM an get another one and want that both FDM
have the same time deviation value).
