3.2 Mechanical installation and lo catio n requirements
It is essential that you read and understand this section before beginning the
installation
.
The safe operation of this equipment depends upon its use in the appropriate environment.
The following points must be considered:
H The NextMove BX
II
must be installed indoors, permanently fixed and located so that it can
only be accessed by service personnel using tools.
H The maximum suggested operating altitude is 2000m (6562ft).
H The NextMove BX
II
must operate in an ambient temperature of 0°C to 40°C (32°F to
104°F).
H The NextMove BX
II
must operate in relative humidity levels of less than 80% for
temperatures up to 31°C (87°F) decreasing linearly to 50% relative humidity at 40°C
(104°F) (non-condensing).
H The NextMove BX
II
must be installed where the pollution degree according to IEC664
shall not exceed 2.
H The external customer supplied 24VDC for the logic supply must be installed so that the
24VDC supplied to the unit is isolated from the AC supply using double or reinforced
insulation.
H The inputs and outputs of the control circuit must be limited to Safety Extra Low V oltage
circuits.
H The atmosphere must not contain flammable gases or vapors.
H There must not be abnormal levels of nuclear radiation or X-rays.
H The NextMove BX
II
must be secured by the slots in the flange, with the protective
earth/ground stud bonded to a safety earth/ground by a 25A conductor.
H The external customer supplied 24VDC logic supply might require a 24V filter .
H Each D-type connector on the front panel of the NextMove BX
II
is secured using two
hexagonal jack screws (sometimes known as “screwlocks”). If a jack screw is removed
accidentally or lost it must be replaced with an identical jack screw with an external male
threaded section of 5mm (0.2 in).
Jack screws with longer threads might result in loose connections.
H The two D-type connectors on the top panel of the NextMove BX
II
are each secured using
two hexagonal jack screws (sometimes known as “screwlocks”). If a jack screw is
removed accidentally or lost it must be replaced with an identical jack screw with an
external male threaded section of 7mm (0.28 in). Jack screws with shorter threads might
result in loose connections.
