Safety summary
1
The following general safety precautions must be observed during all phases of operation, service
and repair of this equipment. Failure to comply with these precautions or with specific warnings
elsewhere in this manual violates safety standards of design, manufacture and intended use of the
equipment. Thrane & Thrane A/S assumes no liability for the customer's failure to comply with
these requirements.
Observe marked areas
Under extreme heat conditions do not touch areas of the terminal or
antenna that are marked with this symbol, as it may result in injury.
Microwave radiation hazards
During transmission the antenna in this system radiates Microwave
Power.This radiation may be hazardous to humans close to the antenna.
When the system is powered, make sure that nobody gets closer than the
recommended minimum safety distance.
The minimum safety distance is 1 m to the side and above the antenna
when the EXPLORER 727 is powered. The safety distance of 1 m does not
apply directly below the antenna, as the radiation forms a hemisphere above the antenna.
La distance de sécurité minimale est de 1 m des parois ainsi que du haut de l'antenne lorsque
l'EXPLORER 727 est allumé. La distance de sécurité minimale ne s'applique pas au-dessous de
l'antenne car la radiation ne forme une sphère qu'au-dessus de l'antenne.
Service
User access to the interior of the system units is prohibited. Only a technician authorized by
Cobham SATCOM may perform service - failure to comply with this rule will void the warranty.
Do not service or adjust alone
Do not attempt internal service or adjustments unless another person, capable of rendering first aid
resuscitation, is present.
Power supply
The voltage range is 10.5 - 32 V DC; 14 A - 5.5 A. Be aware of high start-up peak current:
20 A@24 V, 5 ms.
Do not operate in an explosive atmosphere
Do not operate the equipment in the presence of flammable gases or fumes. Operation of any
electrical equipment in such an environment constitutes a definite safety hazard.
Keep away from live circuits
Operating personnel must not remove equipment covers. Component replacement and internal
adjustment must be made by qualified maintenance personnel. Do not replace components with
the power cable connected. Under certain conditions, dangerous voltages may exist even with the
power cable removed. To avoid injuries, always disconnect power and discharge circuits before
you touch them.
