The safety symbols used conform to the gener-
ally applicable directives and regulations, such as 
DINandANSI.
• Safety instructions that only refer to materi-
al damage are printed in grey, without safety 
symbols.
2.2. General safety information
• The system must be de-energised before any 
work is performed (installation, dismantling, 
maintenance). The alarm switchgear must be 
disconnected from all power sources (electricity 
grid, rechargeable battery)!
• The operator must report any faults or irregulari-
ties that occur to a line manager immediately.
• Where damage occurs to electrical components, 
the housing and/or the cables, the alarm switch-
gear must be shut down immediately by the 
operator.
• The alarm switchgear must not be installed in 
potentiallyexplosiveareas.Thereisariskof
explosions.
These instructions must be strictly observed. 
Non-observance can result in injury or substan-
tial material damage.
2.3. Electrical work
DANGER due to electrical voltage! 
Improper procedures during electrical work 
may result in fatal injuries caused by electrical 
voltage! This work may only be carried out by 
a qualied electrician.
BEWARE of moisture! 
Ingress of moisture will result in damage to 
the alarm switchgear. During installation and 
operation, observe the permissible humidity 
and ensure the alarm switchgear is installed 
so it is overow-proof.
The alarm switchgear is operated on the usual 
power sources. The governing national directives, 
standards and regulations (e.g. VDE 0100) as well 
as the requirements of the local energy supply 
company must be observed for the connection.
The person operating the alarm switchgear must 
know where it is supplied with electrical power 
and how to cut off the supply. A residual-current 
device (RCD) must be provided by the customer.
The section entitled ‘Electrical connection’ must 
be observed when connecting the product. The 
technicalspecicationsmustbeobservedstrictly.
The alarm switchgear must always be earthed. 
Todothis,connecttheprotectiveearthcon-
ductor at the earth terminal indicated (;). The 
cross-section of the cable for the protective earth 
conductor must comply with the local regula-
tions. Alarm switchgear with connected plugs is 
earthed via the plug.
If the alarm switchgear has been switched off 
by a protective device, it must not be switched 
on again until the fault has been corrected.
2.4. Conduct during operation
When operating the alarm switchgear, always 
follow the locally applicable laws and regulations 
for work safety, accident prevention and handling 
electrical products. To help ensure safe working 
practice, the responsibilities of employees should 
beclearlyspeciedbytheoperator.Allpersonnel
are responsible for ensuring that regulations are 
observed.
LEDs on the front of the housing are used to op-
erate the alarm switchgear, display the operating 
status, and signal alarms and faults. The housing 
cover must not be opened during operation.
DANGER due to electrical voltage! 
When working on the uncovered alarm 
switchgear, there is a risk of fatal electric 
shocks. Only operate the alarm switchgear 
with the cover closed!
DANGER - hot surfaces! 
The transformer in the alarm switchgear can 
reach temperatures of up to 70 °C during 
operation. That can heat the housing accord-
ingly.
2.5. Standards and directives applied
See the EC Declaration of Conformity for details 
of the standards and directives used.
2.6. CE marking
The CE marking is attached to the rating plate.
3. Product description
The alarm switchgear has been manufactured 
with great care and is subject to constant quality 
controls. Trouble-free operation is guaranteed if 
they are installed and maintained correctly.
3.1. Intended use and elds of application
DANGER - explosive atmosphere! 
If the connected alarm signals are used in 
potentially explosive areas, they must be 
connected via an intrinsically safe electric 
circuit. Direct connection of the alarm signal 
results in a risk of fatal injury due to explo-
sions. Connections must always be made by a 
qualied electrician.
