• take into consideration that each remote unit transmits an RF signal and the safety volume
must be respected (refer to country regulations for safety volume magnitude);
• remote units must be mounted according to installation instructions;
• Weight and dimensions of case-F remote units should be carefully considered when
choosing the installation site and positioning. During any installation step, please consider
the potential risk of any equipment falling or dropping unexpectedly.
• When choosing the installation site and position, please consider that all remote units must
be accessible for tests and maintenance.

Hazardous locations are those areas “where fi re or explosion hazards may exist due to
fl ammable gases or vapours, fl ammable liquids, combustible dust, or ignitable fi bres or fl yings”.
Safety and Precautions During Installation or Maintenance
During installation, the following tools and equipment will be needed:
Typical electrician tools:
cross-point screwdriver, scissors, pliers, nippers, drill and bits, screws for fi xing remote units to the
wall.
Typical equipment:
proper ladder, scaffolding or air platform for installation of remote units.
CAUTION: some modules are electrostatic-sensitive devices; electrostatic discharges are
caused by direct contact or by an electrostatic fi eld. If a charged body approaches
an electrically conducting surface, the acquired potential is discharged. An equalising
current can than fl ow in the associated circuitry and generate permanently damaging
voltages by induction.
The human body should be grounded at the same potential as the component or
equipment being handled. A wrist strap creates an equipotential electrical connection
between the object and the human.
CAUTION: Do not paint or otherwise coat ION-B equipment.
CAUTION: Great caution should always be used when installing any equipment at a
height higher than 2 meters. Personnel who are installing this equipment should be
informed about the possible risks and safety measures when elevated.
CAUTION: Case-F remote units are provided with door panels which must be handled
with care during installation or maintenance operations. Always switch off the remote
