3.2 Mechanical installation and cooling 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 MicroFlex e100 are shielded correctly.

CAUTION: Avoid locating the MicroFlex e100 immediately above or beside heat generating equipment, or directly below water steam pipes.

CAUTION: Avoid locating the MicroFlex e100 in the vicinity of corrosive substances or vapors, metal particles and dust.

CAUTION: 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:

HThe MicroFlex e100 must be installed indoors, permanently fixed and located so that it can only be accessed by service personnel using tools.

HThe maximum suggested operating altitude is 1000m (3300ft).

HThe MicroFlex e100 must be installed where the pollution degree according to IEC664 shall not exceed 2.

HThe 24VDC control circuit supply must be installed so that the 24VDC supplied to the unit is isolated from the AC supply using double or reinforced insulation.

HThe input of the control circuit must be limited to Safety Extra Low Voltage circuits.

HBoth the AC supply and the 24VDC supply must be fused.

HThe atmosphere must not contain flammable gases or vapors.

HThere must not be abnormal levels of nuclear radiation or X-rays.

HTo comply with CE directive 89/336/EEC an appropriate AC filter must be installed.

HThe MicroFlex e100 must be secured by the slots in the flange. The protective earth/ground (the threaded hole on the top of the MicroFlex e100) must be bonded to a safety earth/ground using either a 25A conductor or a conductor of three times the peak current rating - whichever is the greater.

HThe threaded holes in the top and bottom of the case are for cable clamps. The holes are threaded for M4 bolts no longer than 11mm (0.43 in) in length.

HThe D-type connectors on the front panel of the MicroFlex e100 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 10mm (0.4 in).
