PROJECT PLANNING INFORMATION
Evaluation unit
• See 3.3.6 “Installation
preparation for the
evaluation unit”, page
30
Determine the fitting
location
▸ Install the evaluation unit at an easily accessible location,
preferably at the measuring point. If necessary, install it at a
distance from the measuring point, whereby the total length
of all CAN bus connections in the GM35 measuring system
must not exceed 1000 m.
▸ Ambient temperature between –20 °C and +55 °C.
▸ During continuous operation –40 °C.
Options for CAN bus
wiring
▸ Is the 4 m CAN bus cable sufficient for the connection
between EvU and SR-unit at the selected installation
location?
If not, select a suitable cable (see page 13):
If the distance is less than 19 m: Plan a 15 m prefabricated CAN
bus cable with plug-in connectors.
For larger distances: Use a CAN bus terminal box and the cable
provided by the customer (see page 43).
Assembly platform
Specify the assembly
platform
▸ Provide a suitable working platform for installation on the
outside of a duct/stack.
▸ The fitting location of the GM35 SR-unit should be about 1.3
to 1.5 m above the platform.
▸ The platform must be large enough, secured and positioned
so that all device parts can be accessed without danger. This
is especially important when fitting and removing the SR-unit.
Accident prevention ▸ Applicable (national) regulations on accident prevention must be observed.
▸ Always observe and follow the relevant safety information provided for the
corresponding texts in these Instructions.
