WARNING
Explosion risk!
During installation work, sparks can form and
surfaces may become excessively hot.
▶
Before installation, make sure that there is
not a potentially explosive atmosphere!
▶
For applications in explosive risk zones,
observe the installation and construction
requirements of EN 60079-15 and/or
country-specific regulations.
WARNING
Dangerous contact voltage!
▶
Carry out installation and wiring work on
the maxGUARD station only when the
power supply is disconnected.
▶
Make sure that the place of installation
(panel etc.) has been disconnected from
the power supply!
This section describes the installation and wiring
of a fully configured maxGUARD station in ac
-
cordance with installation drawings and wiring
diagrams.
For planning-related tasks, see the notes in chap-
8.1 Preparations for installation
The u-remote station is designed for installation in control
cabinets, terminals or switch boxes. When fully assembled,
a maxGUARD station meets the requirements of protection
class IP20.
Environmental conditions
Make sure that the permitted environmental conditions for
installation and operation are observed (see general techni-
cal data in section 3.7).
Terminal rail
The maxGUARD station is designed for installation on a ter-
minal rail made from steel or galvanised steel in accordance
with EN 60715 (TH 35-7.5, e.g. Weidmüller TS 35X7.5). The
terminal rail must be fitted before the maxGUARD station is
installed.
The terminal rail must be attached to the substrate at inter-
vals of at least 20 cm to protect it from vibration and impact.
If the terminal rail is mounted on earthed mounting plates, it
does not have to be separately earthed.
Stripping lengths
The required stripping length for every Weidmüller product
is specified in mm (6 mm ± 0.5 mm, ≥ 10 mm ± 1 mm). The
specified value must be complied with. If wire-end ferrules
are used, the stripping length for the respective wire-end
ferrule applies. The outside dimensions of crimped wire-end
ferrules must conform with IEC-60947-1, table 7. For further
information, see the general technical data in section 3.7.
Unpacking the delivery
▶
Please check the delivery for completeness and transport
damage.
▶
Please report any transport damage immediately to the
respective transport company.
ATTENTION
The product can be destroyed by elec-
trostatic discharge!
The components in the maxGUARD series
can be destroyed by electrostatic discharge.
▶
Please make sure that persons and work
equipment are sufficiently earthed!
▶
Unpack all parts and sort the modules into the installation
sequence as per the instructions.
▶
Dispose of all packaging in accordance with the local dis-
posal guidelines. The cardboard packaging from the
maxGUARD components can be sent for paper recycling.
