General information regarding safety
Only skilled qualified personnel are allowed to
perform the described work on the expansion
module. Only skilled qualified electricians are
allowed to work on the electrical system.
For all work performed on EASYLAB components,
the following regulations and guidelines must be
complied with.This applies in particular to the
following German country specific regulations or as
appropriate in the country where the installation is
taking place:
• Equipment and Product Safety Laws (GPSG)
• Industrial Health and Safety Regulations
(BetrSichV)
• Accident Prevention Regulations (BGV A1,
BGV A3)
General safety measures
• Large temperature differences
Condensation can damage the electronics
beyond repair. If the expansion module has been
kept in an unheated area, wait at least two hours
before switching on the supply voltage for
commissioning.
• Electrostatic charge
Electrostatic charge can damage the electronics.
For this reason, first touch an equipotentially
bonded metal surface, e.g. a water pipe, for
electrical earthing before you remove the unit
from its protective wrapping. Avoid skin contact
with any components or printed circuits on the
expansion module or the main PCB.
• Installing the PCB
Tighten the mounting screws and distance pieces
only hand-tight to avoid damage to the PCB or to
the fixing points in the casing.
• Foreign matter and liquids
If liquid gets onto the PCB or inside the
expansion module, let the expansion module
completely dry before commissioning. Remove
foreign matter, if any.
If the device emits a smell or smoke, have it
checked by the manufacturer.

2 Safety and correct use
Correct use
The EM-LON expansion module provides a
LonWorks interface for EASYLAB base
components.
• Use the expansion module only for an EASYLAB
TCU3 controller or a TAM adapter module.
• Use the expansion module only within the
ranges given in the technical data.
• When used on a room controller or adapter
module with active room management function
(RMF) the expansion module provides data for
the entire room.
• When used on a fume cupboard controller, room
controller or adapter module the expansion
module provides access to the data of the
controller.
• Observe the technical data of the expansion
module.
Incorrect use
Do not use the expansion module outdoors, in wet
areas, or in potentially explosive atmospheres.
Residual risks
Failure of the LonWorks interface does not affect
the control function of the volume flow controller but
does affect data exchange with the central BMS.
Additional safety measures are required for
safety-relevant applications.
