Electrical connections
·
Electrical connections must be made with standard cables or compatible, according to the
·
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 is suitable for the power ratings as indicated on the serial number label (
),
and that double or reinforced insulation is used for the power supply.
·
Before powering up, make sure all required cabling is properly connected.
·
Before each use, inspect cabling and connectors for damage.
The equipment described in this document contains electronic components that are susceptible to
electrostatic
discharge
. In order to prevent damage, proper handling procedures must be followed during installation, (dis)connecting
and removing the electronics.
The equipment carries the CE-mark and is
compliant with the concerning EMC requirements
. However, EMC
requirements can only be met using appropriate cables and connector/gland assemblies. Bronkhorst recommends the use
of their standard cables. These cables have the right connectors and loose ends (if any) are marked to help prevent wrong
connection. When using other cables, cable wire diameters must be sufficient to carry the supply current, and voltage loss
must be kept as low as possible.
When connecting the product to other devices, be sure that the integrity of the shielding is not affected;
always use
shielded cabling for signals and communication and do not use unshielded wire terminals.
When in doubt about the suitability of your cabling, contact your Bronkhorst representative.
Always isolate the electrical power before connecting or disconnecting equipment.
4.4
Fieldbus connection
Never
power the instrument simultaneously from
two different power sources
(e.g. fieldbus and Plug-in Power Supply).
Doing so will irreversibly damage the printed circuit board and the instrument will have to be repaired before it can be
used.
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.
