1 SAFETY INSTRUCTIONS
1.1 Software history
The "Electronic Revision" (ER) is consulted to document the revision status of electronic equipment according to NE 53 for all GDC devices. It is easy to see from the ER whether troubleshooting or larger changes in the electronic equipment have taken place and how that has affected the compatibility.
Changes and effect on compatibility
1 Downwards compatible changes and fault repair with no effect on operation (e.g. spelling
mistakes on display)
2-_ Downwards compatible hardware and/or software change of interfaces:
HART
®
H
P PROFIBUS
F Foundation Fieldbus
M Modbus
X all interfaces
3-_ Downwards compatible hardware and/or software change of inputs and outputs:
I Current output
F, P Frequency / pulse output
S Status output
C Control input
CI Current input
X all inputs and outputs
4 Downwards compatible changes with new functions
5 Incompatible changes, i.e. electronic equipment must be changed.

4.4 Connecting the signal cables
DANGER!
Cables may only be connected when the power is switched off.
DANGER!
The device must be grounded in accordance with regulations in order to protect personnel against electric shocks.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation.
WARNING!
Observe without fail the local occupational health and safety regulations. Any work done on the electrical components of the measuring device may only be carried out by properly trained specialists.

4.5 Grounding the measuring sensor
DANGER!
There should be no difference in potential between the measuring sensor and the housing or protective earth of the signal converter!
• The measuring sensor must be properly grounded.
• The grounding cable should not transmit any interference voltages.
• Do not use the grounding cable to connect more than one device to ground.
• The measuring sensors are connected to ground by means of a functional grounding
conductor FE.
• In hazardous areas, grounding is used at the same time for equipotential bonding. Additional grounding instructions are provided in the separate "Ex documentation", which are only supplied together with hazardous area equipment.

DANGER!
The device must be grounded in accordance with regulations in order to protect personnel against electric shocks.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation.
• The protection category depends on the housing versions (IP65...67 to IEC 529 / EN 60529 or NEMA4/4X/6).
• The housings of the devices, which are designed to protect the electronic equipment from dust and moisture, should be kept well closed at all times. Creepage distances and clearances are dimensioned to VDE 0110 and IEC 664 for pollution severity 2. Supply circuits are designed for overvoltage category III and the output circuits for overvoltage category II.
• Fuse protection (I breaker) to isolate the signal converter must be provided close to the device. The separator
