3 Introduction
3 Introduction
This Setup Guide is a systematically structured guideline to assist you with the set-up of your Meinberg product.
The IMS-GPS182 is a 12-channel satellite clock module with GPS technology that has been developed from
the ground up specifically for time and frequency synchronization purposes. The IMS-GPS182 provides a high-
precision, high-accuracy time and frequency reference for your Meinberg IMS system and is designed to receive
signals from the U.S. Global Positioning System (GPS), allowing your Meinberg system to be used anywhere
in the world.
Features
Once the IMS-GPS182 is successfully initialized and synchronized, it distributes a 1PPS (pulse per sec-
ond) reference clock signal and a 10 MHz reference frequency, both of which are critical in determining the
precision and accuracy of the output signals.
The IMS-GPS182 module provides the basis for which the IMS output modules generate a wide variety of
specific output signals used in a diverse range of applications.
Use of Two IMS-GPS182 Modules
In systems equipped with two IMS-GPS182 modules, an RSC switchover module is used to switch between the
two reference sources. The RSC serves to switch over the pulse and frequency outputs and serial interfaces of
the connected reference clocks.
Please refer to the LANTIME Firmware Manual for a more detailed description of all of the status moni-
toring configuration options and features available for your Meinberg product.

4 Important Safety Information
Please ensure that IMS modules designed for "hot-plugging" (modules that are removable and insertable while
a system is in operation) are always handled with the utmost care.
Before performing any maintenance work on the system, Meinberg recommends:
•backing up stored configurations (e.g., via USB flash drive or the Web Interface)
•taking note of the chapter "Prevention of ESD Damage".
•taking note of the chapter "Power Supply".
4.1 Product Documentation
Detailed product documentation is provided on a USB flash drive delivered with the Meinberg system. The
manuals can also be downloaded from the Meinberg website at https://www.meinbergglobal.com, where you can
enter your system name into the search box at the top of the page to find the relevant manual. Alternatively,
contact Meinberg Support for further assistance.
The "Docs & Support" menu on the Web Interface also provides user manuals for time server administrators.
This manual contains important safety instructions for the installation and operation of the
device. Please read this manual thoroughly before using the device.
This device may only be used for the purpose described in this manual. In particular, the
specified operating limits of the device must be heeded. The person setting up the device is
responsible for safety matters in relation to any larger system in which the device is
installed!
Failure to observe these instructions may have an adverse impact on device safety!
Please keep this manual in a safe place.
Target Readership
This manual is only intended to be used by qualified electricians, or by persons who have been appropri-
ately instructed by a qualified electrician and who are familiar with applicable national standards and with
safety rules & regulations. This device may only be installed, set up, and operated by qualified personnel.

4 Important Safety Information
4.2 Prevention of ESD Damage
ATTENTION!
An ESDS device (electrostatic discharge-sensitive device) is any device at risk of damage or
malfunction due to electrostatic discharges (ESD) and thus requires special measures to prevent
such damage or malfunction. Systems and modules with ESDS devices usually bear the following
symbol:
Symbol Indicating Devices with ESDS Components
The following measures will help to protect ESDS components from damage and malfunction.
When preparing to dismantle or install devices:
Ground your body (for example, by touching a grounded object) before touching sensitive devices.
Ensure that you wear a grounding strap on your wrist when handling such devices. These straps must
in turn be attached to an uncoated, non-conductive metal part of the system.
Use only tools and devices that are free of static electricity.
When transporting devices:
Devices must only be touched or held by the edges. Never touch any pins or conductors on the device.
When dismantling or installing devices:
Avoid coming into contact with persons who are not grounded. Such contact may compromise your
connection with the earth conductor and thus also compromise the device’s protection from any
static charges you may be carrying.
When storing devices:
Always store devices 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 device has a lithium battery fitted on it.

4.3 Power Supply
WARNING!
The IMS system in which the module is used is operated at a dangerous voltage. Please refer to your IMS
Manual for more information about safety.
When removing a hot-pluggable power supply unit, always disconnect its power cable before removing it from
the IMS system.
Never open a power supply unit—there may still be hazardous residual voltages present even after disconnec-
tion from the mains supply. In the event that a power supply unit is no longer working (e.g. defective), please
return it to Meinberg for repair.
Failure to observe these safety instructions may result in serious injury and/or property damage. The IMS
system must only be installed, set up, and operated by qualified personnel.
4.4 Handling of Batteries
WARNING!
The lithium battery on the receiver modules has a life of at least ten years. Should it be necessary to replace
it, please note the following:
Improper handling of the battery can lead to an explosion or to a leakage of flammable liquids or gases.
•Never short-circuit the battery.
•Never attempt to recharge the battery.
•Never throw the battery into a fire.
•The battery must only be exposed to the barometric pressure range specified by the battery manufacturer.
•The battery must only ever be replaced with one of the same type or a comparable type recommended by
the manufacturer. The battery must only be replaced by the manufacturer or an authorized technician.
•Never dispose of the battery in a mechanical crusher or shredder, or in an open fire or furnace.
•Please consult your local waste disposal regulations for information on how to dispose of hazardous waste.
ATTENTION!
The battery is used to power components such as the RAM and the reserve real-time backup clock for the
reference clock.
If the battery voltage drops below 3 V DC, Meinberg recommends having the battery replaced. If the battery
voltage drops below the specified minimum, the following behavior may be observed in the reference clock:
•The reference clock may have the wrong date or wrong date upon power-up

4 Important Safety Information
•The reference clock repeatedly starts in Cold Boot mode
•Some of the configurations saved for the reference clock may be lost
4.5 Cabling
WARNING!
Danger of death from electric shock! Never work on cables while the power is live! Always disconnect the
cables from the devices at both ends before working on the plugs and terminals of connected cables!
