Installation of control panel in boiler mounting
plate.
The maximum length of the
transmission wire should be 5m,
with a cross-section of 0,5mm
2
.
Control panel mounting requirements. 1 – control
panel, 2 – vent holes to provide air circulation
(Note: the holes may not cause downgrading of
required IP panel rating.)
12.4 Assembly of module
Working module has to be built-into the
master equipment. Assembly should assure
IP rating appropriate to the environment
conditions, in which the regulator will
operate. Moreover, access of the user to live
parts
under hazardous voltage (e.g.
terminals) should be prevented. Standard
installation housing as shown in below figure
may be used. In such case the user will have
access to front surface of working module.
Housing may be also formed by boiler
elements surrounding the whole module.
Space required for mounting a working
module is shown in below figures. Module
housing does not guarantee dust- or-
waterproofness. To provide the required
protection, appropriate module cover should
be provided.
The working module is designed to be
mounted on a standard DIN TS35 rail. Fasten
the rail firmly to a rigid surface. Prior to
placing the module on the rail, lift up the
catch. Now, place the module on the rail and
press the catch to bring it to the original
position. Make sure the device is firmly
fastened and cannot be easily removed from
the rail without use of tools.
Methods of module installation: a) – in modular
housing with access to front surface, b) – in the
cover without access to front surface, 1- working
module, 2 – DIN TS35 rail, 3 – catch.
For safety reasons, assure the safe distance
between live parts of working module
terminals and conductive (metallic) elements
of housing (min. 10mm) is kept.
Protect connecting wires from tearing,
loosening and tensioning or built them in in
such a way that no load is exerted on them.
