Safety instructions
Definitions
Hazardous voltages have been defined as the ranges: 75 to 1500 Volt DC, and 50 to 1000 Volt AC.
Technicians are qualified persons educated or trained to mount, operate, and also trouble-shoot technically correct and in
accordance with safety regulations.
Operators, being familiar with the contents of this manual, adjust and operate the knobs or potentiometers during normal
operation.
Receipt and unpacking
Unpack the device without damaging it and check whether the device type corresponds to the one ordered. The packing
should always follow the device until this has been permanently mounted.
Environment
Avoid direct sun light, dust, high temperatures, mechanical vibrations and shock, and rain and heavy moisture. If necessary,
heating in excess of the stated limits for ambient temperatures should be avoided by way of ventilation.
All devices fall under Installation Category II, Pollution Degree 2, and Insulation Class II.
Mounting
Only technicians, who are familiar with the technical terms, warnings, and instructions in the manual and who are able to
follow these, should connect the device. Should there be any doubt as to the correct handling of the device, please contact
your local distributor or, alternatively,
PR electronics A/S
www.prelectronics.com
Mounting and connection of the device should comply with national legislation for mounting of electric materials, i.e. wire
cross section, protective fuse, and location. Descriptions of input / output and supply connections are shown in the block
diagram and side label.
The following apply to fixed hazardous voltages-connected devices:
The max. size of the protective fuse is 10 A and, together with a power switch, it should be easily accessible and close to
the device. The power switch should be marked with a label telling it will switch off the voltage to the device.
Year of manufacture can be taken from the first two digits in the serial number.
Instructions for intrinsically safe installation of 5116B
The intrinsically safe circuits are galvanically connected to the communications interface unit.
The communications interface may only be connected temporarily, under the condition that the connectors with terminal
numbers 41...44 and 51...54 are disconnected on the 5116B.
When a higher ingress protection than IP20 is required, this has to be achieved by an additional enclosure which is suitable for
the applicable environmental conditions.
When two or more units are placed next to each other it has to be assured that all the terminal numbers 41...44 and 51...54
are placed on the same side and are separated from the non-intrinsically safe circuits of the units which could be mounted
above or below it.
Each combination of circuits (to terminations 41...44 or to terminations 51...53 or to terminations 51...54) shall be connected
via separated cables or if the combinations are in one cable shall be type A or B in accordance with EN 60079-14 Clause
12.2.2.8.
