Earthing (Grounding); Powering Up - GE Reason RT430 Technical Manual

For compliance with IEC 61010, install a suitable external switch or circuit breaker in each current-carrying
conductor of RT430 power supply; this device should interrupt both the hot (+/L) and neutral (-/N) power
leads. An external 10 A, category C, bipolar circuit-breaker is recommended. The circuit breaker should have
an interruption capacity of at least 25 kA and comply with IEC 60947-2. The switch or circuit-breaker must be
suitably located and easily reachable, also it shall not interrupt the protective earth conductor.
2.7.3

Earthing (Grounding)

To ensure proper operation of the equipment under adverse conditions of electromagnetic compatibility,
connect the equipment protective earth terminal to the panel using a copper strap of at least 10 mm wide
with M6 ring lug. As shown in the below.

Powering Up


Before energizing the unit, be familiarized with all the risk and attention indicators in the equipment
frame;

Connect the power supply (including the ground lead) to the appropriate terminals.

The unit performs a self-test procedure, and the A

At the end of the self-test, the equipment will perform initialization of the GPS receiver. At the end of
approximately one minute the A
equipment's display.

To turn off the unit, disconnect the power supply (including the ground lead) from the terminals. The
unit will record the time, date, satellite orbits parameters, and internal oscillators drift estimates in
non-volatile memory to improve accuracy and reduce the time to synchronize with satellites in the
next energizing process. Also, all front panel indicators will turn off.
In case the unit does not behave in a way here described, carefully check all power and signal connections.
See Chapter 6 manutencao6for additional suggestion for problem diagnosis.
