3 Option: Separate housing
• Comply with the installation and safety instructions in the Operating Instructions.
• Install the device according to the manufacturer's instructions and any other valid standards and
regulations.
• Only install the devices in media for which the wetted materials have sufficient durability.
• Avoid electrostatic charging of the plastic surfaces, for plastic process connections or plastic
coatings.
• The intrinsically safe input power circuit of the device is isolated from ground potential and has a
dielectric strength of at least 500 V
with respect to it.
rms
• Avoid impact or friction sparks for light metal flanges or flange faces (e. g. titanium, zirconium).
• In case of additional or alternative special varnishing of the enclosure or other metallic parts the
danger of an electrostatic charging must be observed. Do not rub surfaces with dry cloth.
LHCR-51
• Mechanically fix rod probes which are more than 3 m (e. g. using guy ropes).
LHCS-51
• Avoid electrostatic charging of the cable.
• Secure probes against swinging.
Service connection • For service operations a field communicator can be connected to the display socket.
• Comply with the safety instructions of the field communicator.
