5. ELECTRICAL CONNECTION
• Improper connection can cause injury or death. The electrical connection must be carried out by a certified electrician.
• Observe the national regulations for electrical installations! By handling products that are supplied by electrical
voltage, you must observe the valid IEC instructions, especially IEC 60364, IEC 61558, IEC 60335, IEC 60598-1
and IEC 60065.
• Before opening an instrument, pull off the main plug and make sure that the instrument is without power supply.
Parts, construction groups or instruments must only be set into operation if they are built into a housing and
protected against touching. During installation they must be without power. Only use tools at the instruments, parts
or construction groups the devices are disconnected from the supply voltage and the electric loads stored in the
construction groups inside the instrument are unloaded. Conducting cables or conductors that are connected to the
instrument, part or construction group must be checked continuously for isolation faults or sites of fractures. If a fault
is found in the supply line, the instrument must be switched off immediately until the defective line has been replaced.
• By using construction elements or groups please make sure that the features for electrical sizes are observed according
to the respective description. In case it is not possible to clarify clearly for a non-commercial end-user which electrical
variables are valid for a part or a construction group, how external wiring is to be undertaken, which external
components or additional devices can be connected and which connection values these external components may
have, always contact an expert for respective information.
• Before operation, generally check if the instrument or construction group is suitable for the field of application. If there
is any doubt, you must confer with a technical expert or the manufacturer of the used construction group.
• Compare specifications on the nameplate and check for the correct supply voltage on the nameplate.
• Feed the power supply cable and signal cables through the appropriate cable entries.
5.1. Terminal Compartment
RISK OF ELECTRIC SHOCK! SWITCH OFF POWER SUPPLY BEFORE OPENING THE DEVICE. DO NOT INSTALL OR WIRE THE
DEVICE WHILE IT IS CONNECTED TO THE POWER SUPPLY. DISREGARDING COMPLIANCE WITH THIS PRECAUTION MAY
RESULT IN IRREPARABLE DAMAGE TO THE ELECTRONICS.
MPORTANTI
• Protective grounding: Suitable measures for error protection must be carried out. The conductive system parts to be protected
must be connected to a suitable earthing conductor via the PE conductor, so that the system parts with a fault are switched off
by overcurrent protection devices
• Electronic Discharge: Electronic components can be destroyed by electrostatic discharge during in-stallation. Avoid high
electrostatic charges by using suitable grounding measures.
• Disconnecting device: The device must be connected and disconnected to the mains by means of a disconnecting device.
• Power / connection cable: Upon delivery, the transmitter power cable is already connected. If necessary, use a strain relief for
the connected cable to prevent accidental disconnection.
• The system has no on / off switch. It is therefore imperative to attach the system to an additional circuit breaker (at least 2A) to
disconnect the system from the power supply in the event of a fault or repair. The circuit breaker should be within easy reach.
• It is necessary to connect the system to an external overvoltage protection device (for example, a circuit breaker).
