1.1 Safety instructions
9
Opening the device during the guarantee period will render the guarantee
null and void.
 Before opening the device, make sure that the device is disconnected from the mains.
Switching off the device by its power button does not disconnect it from the mains.
Complete disconnection is only possible if the power cable is removed from the wall
plug or from the device. Ensure that there is free and easy access to enable discon-
nection.
 If the system is expanded, you must observe the following:
-
that all effective legal regulations and all technical data are adhered to
-
the power consumption of any add-on card does not exceed the specified limitations
-
the current consumption of the system does not exceed the value stated on the
product label.
 Switch off and ensure that the device cannot be operated if the following apply because
safe operation may no longer be possible:
-
the device has visible damages or
-
the device is no longer functioning
 The GN series device may only be opened in accordance with the description in this
manual for:
-
Replacing the lithium battery.
-
Configuration of the RS422/RS485 interfaces.
These procedures have to be carried out by qualified personnel only.
Additional safety instructions for DC power supply circuits
 To guarantee safe operation of devices with DC power supply voltages greater than 60V
DC or a power consumption larger than 240VA, please observe that:
-
the device is set up, installed and operated in a room or enclosure marked with
“RESTRICTED ACCESS” if there are no safety messages on the device itself such as
safety signs or labels.
-
no cables or parts without insulation in electrical circuits with dangerous voltage or
power should be touched directly or indirectly
-
a reliable protective earthing connection is provided
-
a suitable, easily accessible disconnecting device is used in the application (e.g.
overcurrent protective device) if the device itself cannot be disconnected
-
a disconnect device, if provided in or as part of the equipment, shall disconnect both
poles simultaneously
-
interconnecting power circuits of different devices cause no electrical hazards
 A sufficient dimensioning of the power cable wires must be selected – according to the
maximum electrical specifications on the product label – as stipulated by EN60950-1 or
EN60204 or UL508 regulations.
 Take care that there are no cables, particularly power cables, in areas where persons
can trip over them.
