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 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.
2.6 Safety during Maintenance WARNING! The device must not be opened. Repairs to the device may only be carried out by the manufacturer or by authorized personnel. Improper repairs can result in considerable danger to the user (electric shock, fire hazard). Unauthorized opening of the device or of individual parts of the device can also lead to considerable risks for the user and result in a loss of warranty as well as an exclusion of liability.
2 Important Safety Information 2.8 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.

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 M300/GPS 3 Global Information LANTIME M300/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.
