Be aware of the following information before installing in hazardous
locations.
- Power must be deenergized
before installing the system.
- The carrier is intended to
be mounted vertically on a panel in an increased safety enclosure.
For Marine Certified DeltaV installations, refer to the following
installation requirements. These requirements allow the DeltaV system to
support the reduced EMC interference requirements at the Marine Navigation
Frequencies.
For all exposed deck locations:
- Install the DeltaV system in
an IP66/NEMA 4 enclosure with EMC-reduction shielding (15 dB minimum) such as
the Stahl Series 8125/8126 enclosures.
- The door of the enclosure
must remain closed during normal operation. Opening the door defeats
EMC-reduction shielding and protection from electrostatic discharge. Open the
door only for maintenance and repair performed by certified, trained personnel.
- Include an EMC power line
filter such as a Tyco S series or equivalent on all DC input leads at the
DeltaV system's enclosure with the filter grounded at the enclosure.
- Ensure that the equipment is
maintained in a non-condensing humidity environment as the leakage current
detection circuit shuts the equipment down in the presence of condensing
humidity.
For non-exposed deck locations:
- Install the DeltaV system in
an enclosure suitable for your environment with EMC-reduction shielding (15 dB
minimum).
- The door of the enclosure
must remain closed during normal operation. Opening the door defeats
EMC-reduction shielding and protection from electrostatic discharge. Open the
door only for maintenance and repair performed by certified, trained personnel.
- Include an EMC power line
filter such as a Tyco S Series or equivalent on all DC input leads at the
DeltaV system's enclosure with the filter grounded at the enclosure.
