Connecting additional electrical equipment
When working on electrical systems there is
a risk of danger to life due to electrocution.
◆ The connection of additional electrical equipment
must only be carried out by a qualified electrician.
◆ Before opening the protective cover always dis-
connect the equipment from the mains power supply
and check that the system is free of voltage.
Accessories from other manufacturers may
result in malfunctions or damage to property.
◆ Use only original accessories. A separate source
voltage at the screwtype terminal for the external
switch will result in a short circuit and will destroy
the door operator’s electronics.
◆ Do not connect any separate source voltages to the
terminal for the external switch. The terminals are
potential-free contacts.
