Mechanical installation
ƒ Install the product according to the regulations of the corresponding
documentation. In particular observe the section "Operating conditions" in the
chapter "Technical data".
ƒ Provide for a careful handling and avoid mechanical overload. During handling
neither bend components, nor change the insulation distances.
ƒ The product contains electrostatic sensitive devices which can easily be damaged by
short circuit or static discharge (ESD). Thus, electronic components and contacts
must not be touched unless ESD measures are taken beforehand.
Electrical installation
ƒ Carry out the electrical installation according to the relevant regulations (e. g. cable
cross−sections, fusing, connection to the PE conductor). Additional notes are
included in the documentation.
ƒ When working on live products, observe the applicable national regulations for the
prevention of accidents (e.g. BGV 3).
ƒ The documentation contains information about EMC−compliant installation
(shielding, earthing, arrangement of filters and laying cables). The system or
machine manufacturer is responsible for compliance with the limit values required
by EMC legislation.
Warning: The controllers are products which can be used in category C2 drive systems
as per EN 61800−3. These products may cause radio interference in residential areas. If
this happens, the operator may need to take appropriate action.
ƒ For compliance with the limit values for radio interference emission at the site of
installation, the components − if specified in the technical data − have to be mounted
in housings (e. g. control cabinets). The housings have to enable an EMC−compliant
installation. In particular observe that for example control cabinet doors preferably
have a circumferential metallic connection to the housing. Reduce openings or
cutouts through the housing to a minimum.
ƒ Only plug in or remove pluggable terminals in the deenergised state!
Commissioning
ƒ If required, you have to equip the system with additional monitoring and protective
devices in accordance with the respective valid safety regulations (e. g. law on
technical equipment, regulations for the prevention of accidents).
Maintenance and servicing
ƒ The components are maintenance−free if the required operating conditions are
observed.
ƒ If the cooling air is polluted, the cooling surfaces may be contaminated or the air
vents may be blocked. Under these operating conditions, the cooling surfaces and air
vents must be cleaned at regular intervals. Never use sharp objects for this purpose!
ƒ After the system has been disconnected from the supply voltage, live components
and power connections must not be touched immediately because capacitors may
be charged. Please observe the corresponding notes on the device.
