WARNING
ENG
Read the following warnings before installing, connecting or using the device:
• follow instructions precisely when connecting the device.
• always use cables that are suitable for the voltage and current levels indicated in the technical specifications.
• In applications with risk of damage to persons, machines or materials, you MUST install auxiliary alarm devices.
• It is advisable to verify frequently that the alarm device is functional even during the normal operation of the equipment.
• DO NOT operate the device in rooms with dangerous (inflammable or explosive) atmosphere.
• During continuous operation, the heat sink can reach up to 100°C / 212°F, and stays at a high temperature even after the device is turned off due
to thermal inertia; therefore, DO NOT touch it and avoid contact with electrical wires.
• do not work on the power part without first disconnecting electrical power to the panel.
• do not remove the cover when the device is powered!
Installation:
• correctly ground the device using the specific terminal.
• power supply lines must be separated from device input and output lines; always check that the supply voltage matches the voltage indicated on
the device label.
• avoid dust, humidity, corrosive gases and heat sources.
• respect the installation distances between one device and another (to allow for dissipation of generated heat).
• to keep air in movement, we advise you to install a fan near the GRM-H group in the electrical panel containing the GRM-H.
• respect the indicated dissipation curves
Maintenance:
at regular intervals, check operation of the cooling fans and clean all
air ventilation filters.
• repairs must be done out only by trained and specialized personnel. Cut power to the device before accessing internal parts.
• do not clean the box with solvents derived from hydrocarbons (trichloroethylene, gasoline, etc.). Using such solvents will compromise the device's
mechanical reliability. Use a clean cloth moistened with ethyl alcohol or water to clean external parts in plastic.
Service:
GEFRAN has a service department.
The warranty excludes defects caused by any use not conforming to these instructions.
