Mounting
• The unit should be mounted at a location that is free of vibrations.
The permissible ambient temperature (recommended or
permissible operating temperature) must not be exceeded (see
Technical Data).
• Operation of the unit operates outside the permissible operating
temperature range may lead to measurement errors and to failure
of the signal converter.
• Plastic housing, overvoltage category III acc. to
DIN EN 61010 Part 1.
• The signal converter can be snapped onto a 35 mm
DIN EN 50022 rail.
• The units may only be operated in closed cubicles or cabinets.
Alternatively, they must be mounted in places that are accessible
to qualified personnel only.
Connection
• The electrical installation must be carried out in conformity with the
regulations for the erection of electrical power installations.
• The auxiliary power supply must be protected against short circuits
by a fused external disconnector. The selected fuse dimension
depends on the cross-section of the connecting wires. The external
disconnector must be identified appropriately.
• Only FO cable assemblies of the specified types may be used.
• For permissible types of FO cables, please refer to the Technical
Data.
• The permissible optical budget must be adhered to (chapter 1.3,
Technical Data).
• When wiring FO cables, the specified bending radius must be
observed.
• Conductor diameters for screw-type terminals:
Auxiliary power:
max. 2.5mm²
Fault signal output:
max. 2.5mm²
With stranded conductors, insulated end sleeves must be used
to prevent fraying of the conductor end.
Warning !
Recommended stripping length:
3-5 mm
All stipulations and execution statements of Accident Prevention Re-
gulation VBG 4.0 must be adhered to, in particular Section 8:
"Admissible deviations when working on live parts". The tools used
must be suited for working on electrical installations.
Warning !
OPERATION OF THE UNIT WITH THE HOUSING REMOVED IS
NOT PERMITTED.
