Mounting and service work
The device may only be installed and operated by qualified persons (in accordance with EN 62368-1) or by persons who have
been instructed by experts in accordance with the rules of technology. Maintenance work may only be carried out by qualified
service personnel. Before starting the service work, switch off the operating voltage and secure it against being switched on
again. In the event of service or danger, the mains plug serves as a disconnect device from the mains voltage and must
therefore be accessible and usable at all times. In order to guarantee interference immunity, all device covers must be
screwed tight again after opening.
Fuses are only to be changed by authorised specialists. Only fuses of the same type may be used.
Repairs
Repairs may only be carried out by the manufacturer. Improper repairs can pose significant risks to the user. In the event of
malfunctions, the device must be disconnected from the mains and authorised specialist personnel must be consulted. If
necessary, the device must be sent to the manufacturer.
Thunderstorm
According to EN 60728 part 1 safety requirements, due to increased risk of lightning, maintenance and / or installation work
should not be carried out during thunderstorms on the device or the system.
High overvoltages (lightning strikes, overvoltages in the power grid) can damage insulation that serves to protect against
mains voltage.
Ambient temperature
The permissible ambient temperatures specified in the technical data must be observed for operation and storage, even if the
climatic conditions change due to external influences (solar radiation etc.). Overheating the device can damage the insulation
that serves to isolate the mains voltage.
Termination
Unused coaxial connections should be terminated with 75 Ohm terminating resistors. For DC-supplied connections, DC
voltage decoupling must be used or use 75 Ohm terminating resistors with integrated DC decoupling.
Attention
This module contains ESD components! (ESD = Electrostatic Sensitive Device).
An electrostatic discharge is an electrical current pulse, which can flow through an electrically insulated material, when
triggered by a large voltage difference. To ensure the reliability of ESD components, it is necessary to consider their most
important handling rules:
» Pay attention permanently to potential equalisation (equipotential bonding)!
» Use wrist straps and approved footwear for personnel grounding!
» Avoid electrostatically chargeable materials such as normal PE, PVC, polystyrene!
» Avoid electrostatic fields >100 V/cm!
» Use only labeled and defined packing and transportation materials!
Damage caused by faulty connections and/or improper handling are excluded from any liability.
Recycling
All of our packaging materials (packaging, identification sheets, plastic foil and bags) are fully recyclable. The devices are to
be disposed of properly according to the current disposal regulations of your district/country/state as electronic scrap.
