Instructions For Intrinsically Safe Installation Of 5116B - PR Elecronics 5116 Handbuch

MOUNTING
Only technicians who are familiar with the technical terms, warnings, and
instruc tions in the manual and who are able to follow these should connect the
module. Should there be any doubt as to the correct handling of the module,
please contact your local distributor or, alternatively,
PR electronics A/S, lerbakken 10, DK-8410 Rønde, Denmark,
Mounting and connection of the module 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 modules:
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 module. The
power switch should be marked with a label telling it will switch off the
volt age to the module.
Year of manufacture can be taken from the first two digits in the serial number.

NSTRUCTIONS 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 tempo rarily, 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.
