2.3 Electrical connection
· Electrical connections should be made according to the applicable
as included) or compatible, with respect to required supply current, voltage loss, cable length, cable and gland diameters
and operating conditions.
· When using self-assembled cables, follow the guidelines provided by the connectors' manufacturer.
· For use in a fieldbus system, follow the instructions of the cable supplier for the according fieldbus system.
Make sure that the power supply matches the power rating of the instrument (see
·
double or reinforced insulation is used for the power supply.
· If a surge protection device is used, make sure its specifications match the power consumption of the application.
To prevent damage as a result of reversed polarity, the use of a 2A fuse in the direct +Us line is recommended.
Always turn off electrical power before connecting or disconnecting equipment electrically.
In order to be able to comply with all applicable guidelines and regulations, it is imperative that electrical connections
be made by or under supervision of a qualified electrician.
The equipment described in this document contains electronic components that are susceptible to electrostatic
·
discharge.
· When working on the electrical installation, take appropriate measures to prevent damage as a result of
electrostatic discharge.
The CE mark on the equipment indicates that it complies with requirements imposed by the European Union.
The UKCA mark indicates compliance with requirements imposed by the United Kingdom.
In both cases, the requirements include electromagnetic compatibility (EMC).
EMC can only be guaranteed by applying appropriate cables and connectors or gland assemblies:
· Cable wire diameters must be sufficient to carry the supply current and minimize voltage loss.
· When connecting the product to other devices, ensure that the integrity of the shielding remains uncompromised;
use shielded cables and connectors where possible and/or required.
· Preferably use the supplied cables (if applicable) to make electrical (signal) connections to and between the
supplied components. These cables are shielded, have the required wire diameter, and loose ends (if applicable) are
marked to facilitate correct connection.
If not all requirements for proper shielding can be met (for example, because a component is not equipped with
shielded connectors), take the following measures to ensure the best possible shielding:
· Keep cable lengths at a minimum.
Route cables as closely as possible alongside metal structures or components.
·
· Ensure all electrical components are grounded to earth.
When in doubt about the shielding of your cabling and/or electrical connections, contact your Bronkhorst
representative.
2.4 Fieldbus connection
Always check the total power consumption of your instruments before connecting them to a fieldbus system. Do not
exceed the maximum power of the power supply unit.
