2 Important Safety Information AC Power Supply DC Power Supply The device is a device of protection Outside the assembly group the device must be • • class 1 and may only be connected to a disconnectable from power supply grounded outlet (TN system).
2.4 Protective Conductor- / Ground-Terminal ATTENTION! In order to ensure safe operation and to meet the requirements of IEC 62368-1, the device must be correctly connected to the protective earth conductor via the protective earth connection terminal. If an external earth connection is provided on the housing, it must be connected to the equipotential bonding rail (grounding rail).
2 Important Safety Information 2.5 Fuse Replacement WARNING! This equipment is operated at a hazardous voltage. Danger to life due to electrical shock! Disconnect the device from the mains! To do this, press the disconnector (switch). Then, loosen the locking screws of the supply plug (if present) and pull it off.
2.6 Safety during Operation WARNING! Avoiding Short-Circuits Make sure not to get any objects or liquids inside the unit. Electric shock or short circuit could result. Ventilation Slots Make sure that the ventilation slots are not covered or dusty, as there is a danger of overheating during operation.
2 Important Safety Information 2.7 Safety during Maintenance WARNING! When you are expanding the device, use only device parts that are approved for the system. Non-observance may result in injury to the EMC or safety standards and cause malfunction of the device. If device parts, which are released for the system, are extended or removed there may be a risk of injury in the area of the hands, due to the pull-out forces (approx.
2.9 Cleaning and Care ATTENTION! Do not wet clean the appliance! Penetrating water can cause considerable dangers to the user (e.g., electric shock). Liquid can destroy the electronics of the device! Liquid penetrates into the housing of the device and can cause a short circuit of the electronics. Only clean with a soft, dry cloth.
Return and Collection Systems For returning your old equipment, please use the country-specific return and collection systems available to you or contact Meinberg. The withdrawal may be refused in the case of waste equipment which presents a risk to human health or safety due to contamination during use.
3 Global Information LANTIME M400/GPS LANTIME stands for Local Area Network Timeserver. The LANTIME provides an absolute and highly precise time reference in a TCP/IP network (stratum 1 server). The time is made available to all NTP clients by NTP protocol (Network Time Protocol) and allows a simple integration of an absolute time reference into an existing network.
