3.2 Mechanical installation and cooling requirements
It is essential that you read and understand this section before beginning the
installation
.
To prevent equipment damage, be certain that the input power has correctly rated
protective devices installed.
To prevent equipment damage, be certain that input and output signals are powered
and referenced correctly.
To ensure reliable performance of this equipment be certain that all signals to/from
the MicroFlex
e
100 are shielded correctly.
Avoid locating the MicroFlex
e
100 immediately above or beside heat generating
equipment, or directly below water steam pipes.
Avoid locating the MicroFlex
e
100 in the vicinity of corrosive substances or vapors,
metal particles and dust.
Failure to meet cooling air flow requirements will result in reduced product lifetime
and/or drive overtemperature trips.
The safe operation of this equipment depends upon its use in the appropriate environment.
The following points must be considered:
H
The MicroFlex
e
100 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 1000 m (3300 ft).
H
The MicroFlex
e
100 must be installed where the pollution degree according to IEC664 shall
not exceed 2.
H
The 24 VDC control circuit supply must be installed so that the 24 VDC supplied to the unit
is isolated from the AC supply using double or reinforced insulation.
H
The input of the control circuit must be limited to Safety Extra Low Voltage circuits.
H
Both the AC supply and the 24 VDC 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
To comply with CE directive 89/336/EEC an appropriate AC filter must be installed.
H
The MicroFlex
e
100 must be secured by the slots in the flange. The protective earth/ground
(the threaded hole on the top of the MicroFlex
e
100) must be bonded to a safety earth/ground
using either a 25 A conductor or a conductor of three times the peak current rating -
whichever is the greater.
H
The threaded holes in the top and bottom of the case are for cable clamps. The holes are
threaded for M4 bolts no longer than 11 mm (0.43 in) in length.
H
The D-type connectors on the front panel of the MicroFlex
e
100 are secured using two
hexagonal jack screws (sometimes known as “screwlocks”). If a jack screw is removed
accidentally or lost it must be replaced with a #4-40 UNC jack screw with an external male
threaded section no longer than 10 mm (0.4 in).
