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.
