All annunciators have an appropriate package for air or road transportation. When receiving the
equipment, the visual inspection may be carried out to check if there were damages during
transportation. If so, it is necessary to contact immediately the receiving sector of your company,
which may notify your insurance company and Mauell so the involved parts may adopt the necessary
measures to repair the damages and to initiate the reimbursement of eventual expenses.
The incorrect use and wrong handling of the equipment are not covered by Mauell general
guarantee. Therefore, it is essential that the installer takes some measures, before executing the
installation and powering of the equipment, as mentioned below:
Avoid mechanical impacts to the equipment or falls, which cause frame arching or back
terminal breaking.
Avoid that water or other liquid gets into the annunciator, as the liquid may cause short-
circuit to the internal circuits and, consequently, bad contacts in the future.
Avoid that external objects get into the annunciator through the vents, thus, whenever it is
necessary to carry out any work involving drilling or panel plate thinning, where the
annunciator is installed, the equipment may be protected with paper, plastic and other
material so the debris do not get into the annunciator, causing poor operation.
Check the voltage levels and the correct identification of the cables before executing the
equipment connection. A wrong connection can cause short-circuit and damage to the
equipment in an irreparable way.
The frontal modules may be removed with the aid of a blade, which may be inserted
between two modules, carefully, forcing the removal of the desired module. This operation
may be carried out carefully and patiently in order to prevent damages to the front part of
the modules or to the grid brackets of the module.
The access to the electronic circuits of the equipment is carried out from the front part,
removing the front modules, as described above, disconnecting the back pluggable
terminals, without disconnecting the wires, from which the electronic part of the equipment
may be removed. After the repair, the electronic part may be replaced and the terminals
plugged again. When reconnecting, note with the maximum care, the proper position of
each terminal.
The cleaning of the front part of the annunciator may be carried out with a soft cloth,
slightly wet, with neutral detergent. The equipment may not be submitted to the direct
spray of liquids and care must be taken so the liquids do not get into it.
