Warning
The successful and safe operation of this device is dependent on proper handling and installation
by qualified personnel under observance of all warnings and hints contained in this manual.
In particular the general erection and safety regulations (e.g. IEC, DIN, VDE, or national standards)
regarding the correct use of hoisting gear must be observed. Non-observance can result in death,
personal injury or substantial property damage.
5.1
Unpacking and repacking
When dispatched from the factory, the equipment is
packed in accordance with the guidelines laid down
in IEC 60255---21, which specifies the impact resis-
tance of packaging.
This packing shall be removed with care, without
force and without the use of inappropriate tools. The
equipment should be visually checked to ensure
that there are no external traces of damage.
The transport packing can be re-used for further
transport when applied in the same way. The stor-
age packing of the individual relays is not suited to
transport. If alternative packing is used, this must
also provide the same degree of protection against
mechanical shock, as laid down in IEC 60255---
21---1 class 2 and IEC 60255---21---2 class 1.
Before initial energization with supply voltage, the
relay shall be situated in the operating area for at
least two hours in order to ensure temperature
equalization and to avoid humidity influences and
condensation.
5.2
Preparations
The operating conditions must accord with VDE
0100/5.73 and VDE 0105 part 1/7.83, or correspond-
ing national standards for electrical power installa-
tions.
The modules of digital relays contain
CMOS circuits. These shall not be with-
drawn or inserted under live conditions!
The modules must be so handled that any
possibility of damage due to static electri-
cal charges is excluded. During any neces-
sary handling of individual modules the re-
commendations relating to the handling of
e
lectrostatically
e
ndangered
c
omponents
(EEC) must be observed.
!
Caution!
In installed conditions, the modules are in no dan-
ger.
