Use an on-site, 2-pole automatic circuit breaker with locking option, according to the permissible current car-
X
rying capacity of the cable, as the disconnecting device on the mains side.
After the system housing has been opened, live parts are exposed. The connecting terminals for system compo-
nents in parts have a low voltage of ≤50 V.
Do not the activate the mains and battery voltage until all the system components have been connected.
X
When replacing the batteries use only batteries approved by GEZE.
X

X
à ASR A1.7 "Guidelines for doors and gates"
à DIN VDE 0100-600 "Setting up of low-voltage installations"
à DIN EN 60335-2-103 "Safety of electrical devices for home use and similar purposes; special requirements
for drives for gates, doors and windows"
à Accident prevention regulations, in particular DGUV Regulation 1 "Accident prevention regulations,
principles of prevention" and DGUV Regulation 3 "Accident prevention regulations, electrical systems and
equipment".
à VDE 0833 "Alarm systems for fire, intrusion and hold-up"

à MLAR "Model Guideline for Line Systems"
The measures for security and prevention of crushing, impact, shearing or drawing-in spots, in particular at
X
points with a height of less than 2.5 m are to be considered and carried out.
One measure is, for example, to use a switch with an OFF default setting (for example GEZE vent switch LTA-
LSA Mat. No. 118476). In the case of children or persons with a limited ability to judge, a key-operated switch
with an OFF default setting has to be used (e.g. GEZE Mat. No. 117996 for SCT, 090176 for cylinder). The switch
has to be mounted so that the points of danger can be seen.
