Safety instructions

Intended use
The RM4220 amplifier is to be used exclusively for measurement tasks and dir­
ectly related control tasks within the application limits detailed in the specifica­
tions. Use for any purpose other than the above is deemed to be non‐desig­
nated use.
The RM4220 amplifier is designed for installation in EMC‐proof housings (e.g.
control cabinet).
In the interests of safety, the device should only be operated by qualified per­
sonnel as described in the Operating Manual and taking into account the spe­
cifications. It is also essential to comply with the legal and safety requirements
for the application concerned during use. The same applies to the use of
accessories.
The scope of supply and performance of the RM4220 covers only a small area
of measurement technology. In addition, equipment planners, installers and
operators should plan, implement and respond to the safety engineering con­
siderations of measurement technology in such a way as to minimize remain­
ing dangers. On‐site regulations must be complied with at all times. There must
be reference to the remaining dangers connected with measurement techno­
logy.
Each time, before commissioning, you must first run a project planning and risk
analysis that takes into account all the safety aspects of automation techno­
logy. This particularly concerns personal and machine protection. Additional
safety precautions must be taken in plants where malfunctions could cause
major damage, loss of data or even personal injury. In the event of a fault,
these precautions must establish safe operating conditions. This can be done,
for example, by mechanical interlocking, error signaling, etc.
Ambient conditions on site
• Protect the device from direct contact with water (IP20).
• Please observe the permissible maximum ambient temperatures stated in
the specifications.
Conversions and modifications
The RM4220 amplifier must not be modified from the design or safety engin­
eering point of view except with our express agreement. Any modification shall
exclude all liability on our part for any damage resulting therefrom.
In particular, any repair or soldering work on motherboards (replacement of
components) is prohibited. When exchanging complete modules, use only ori­
ginal parts from HBM.
