3-4 Basic Installation MN1902
3.2 Mechanical installation and location requirements
It is essential that you read and understand this section before beginning the
installation
.
CAUTION : To prevent equipment damage, be certain that the input power has
correctly rated protective devices installed.
CAUTION : To prevent equipment damage, be certain that input and output signals
are powered and referenced correctly.
CAUTION : To ensure reliable performance of this equipment be certain that all
signals to/from the FlexDrive
II
are shielded correctly.
CAUTION : Avoid locating the FlexDrive
II
immediately above or beside heat
generating equipment, or directly below water steam pipes.
CAUTION : Avoid locating the FlexDrive
II
in the vicinity of corrosive substances or
vapors, metal particles and dust.
The safe operation of this equipment depends upon its use in the appropriate environment.
The following points must be considered:
H
The FlexDrive
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 1000m (3300ft).
Above 1000m (3300ft) de-rate output current 1.1% per 100m (330ft).
H
The FlexDrive II must operate in an ambient temperature of 0°C to 40°C (32°F to 104°F).
De-rate output current 2.5% per 1°C (1.8°F) from 40°C (104°F) to 50°C (122°F) maximum.
H
The FlexDrive
II
must operate in relative humidity levels of less than 90% for temperatures
up to 31°C (87°F) decreasing linearly to 50% relative humidity at 40°C (104°F)
(non-condensing).
H
The FlexDrive 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 Voltage
circuits.
H
Both the AC supply and the external 24VDC supply must be fused.
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 FlexDrive
II
must be secured by the slots in the flange, with the protective
earth/ground stud bonded to a safety earth/ground by either a 25A conductor or a
conductor of three times the peak current rating - whichever is the greater.
