WG20 Instructions 3
• If this is the first time that you install a WG20 gate automation system
we recommend that you dedicate some of your time to reading this man-
ual. You should read it before you start installing the system, so you don't
have to rush to finish the work.
Keep all the components of the WG20 system handy so that you can
read, check and verify all the information contained in this manual. How-
ever, do not carry out the adjustment and memorization stages other-
wise, during the actual installation of the products, you will have to deal
with settings that differ from the original factory ones.
• When reading this manual, pay special attention to the sections marked
by the following symbol:
these sections are particularly important for safety.
• Store this manual safely for future use.
• This manual, as well as the design and manufacture of the devices that
make up WG20, comply fully with the standards and regulations in force.
• Considering the hazards that may exist during the installation and
operation of WG20, it is necessary that also the installation be carried out
in strict compliance with current legislation, standards and regulations,
particularly:
• This manual contains important information regarding personal
safety; before you start installing the components, it is important
that you read and understand all the information contained here-
in. Do not proceed with the installation if you have doubts of any
sort; if necessary, refer to the MHOUSE customer service depart-
ment for clarifications.
• Before you start with the installation, make sure that each sin-
gle WG20 device is suitable for the intended automation purpos-
es; pay special attention to the data provided in chapter 6 "Tech-
nical Characteristics". If even a single device is not suitable for
the intended application, do not proceed with the installation.
• Before you start with the installation, check whether additional
devices or materials are needed to complete the automation with
WG20 based on the specific application requirements.
• The WG20 automation system must not be used until the
automation has been commissioned as described in paragraph
3.7.2 "Commissioning".
• The WG20 automation system cannot be considered as a suit-
able intrusion protection system. If you require efficient protec-
tion you need to integrate WG20 with other devices.
• The packing materials for WG20 must be disposed of in com-
pliance with local regulations.
• Do not make modifications to any components unless provided
for in this manual. This type of operations will only cause mal-
functions. MHOUSE disclaims any liability for damage resulting
from modified products.
• Do not immerse the automation parts in water or any other liq-
uid. During installation, ensure that water does not leak into the
control unit or other open devices.
• In the event that liquid substances have penetrated inside the
automation devices, immediately disconnect the power supply
and contact the MHOUSE customer service department. The use
of WG20 in these conditions can be dangerous.
• Keep all components of WG20 away from heat sources and
open flames; these could damage the components and cause
malfunctions, fire or dangerous situations.
• During long periods of inactivity, the optional battery (PR1)
should be removed and stored in a dry location to prevent leak-
age of noxious substances.
• Connect the control unit only to a power supply line equipped
with safety grounding system.
• All operations requiring the opening of the protection shell of
any WG20 device must be performed with the control unit dis-
connected from the power supply (and from the PR1 buffer bat-
tery, if featured); if the disconnection device is not identifiable,
post the following sign on it: "WARNING: MAINTENANCE WORK
IN PROGRESS".
• In the event that any automatic switches or fuses are tripped,
you must identify the failure and eliminate it before you reset
them.
• If a failure occurs that cannot be solved using the information
provided in this manual, refer to the MHOUSE customer service
department.
