5.4 Matters Need Attention
5.4.1 When installing GGF series isolation power cabinet, it is necessary to strictly abide by the
national electrical operation rules. No live operation is allowed. Please ask professional electrician to
install, otherwise there may be electric shock accident.
5.4.2 The GGF series isolation power cabinet shall be installed in strict accordance with the electrical
specifications. It is necessary to connect the equipotential terminal block of the isolation power cabinet
to the equipotential terminal box on site to ensure reliable grounding of the cabinet.
5.4.3 The GGF series isolation power cabinet can be installed indoors according to different
installation methods. The shell protection level is IP31. Ensure safe operation.
Power distribution devices such as circuit breakers in the isolation power cabinet can be selected
according to the actual situation. Pay attention to the specifications and models. Any isolation
transformer will generate impulse current when starting up. Therefore, when selecting the circuit
breaker of the inlet circuit of the isolation transformer, the circuit breaker with the trip curve of D
curve or the circuit breaker with the C and D trip curve of the national standard GB14048.2-2008
should be selected. The rated current of the circuit breaker is determined according to the capacity of
the isolation transformer as follows: 10kVA –63A; 8kVA –50A; 6.3kVA –40A; 5kVA –40A; 3.15
kVA –20A. The circuit breaker used in the inlet and outlet circuit of the isolation transformer should
only have short circuit protection, without overload protection. If the appropriate circuit breaker is not
selected according to the above requirements, the company shall not assume any responsibility for the

9/ 11
medical accident caused by the circuit breaker's difficulty in closing or the interruption in the operation
process.

fault locator products in-cabinet, refer to 076 Intelligent Insulation Monitoring Products of Medical IT
System (Five-piece) Installation and Operation Manual and 077 Insulation Monitoring and Fault
Location Products of Medical IT System (Seven-piece) Installation and Operation Manual.
6 Operation and Usage
After the product is installed, the following operations should be done:
If the GGF series isolation power cabinet is equipped with a dual power automatic transfer switch,
ensure the reliability of the dual power supply. The power cabinet should be able to quickly switch to
the standby power supply when the current working power supply is cut off. For example, if the
current working power supply is power A and the standby power supply is power B, cut off power
supply A and switch on power supply B quickly to ensure continuous power supply.
The GGF series isolation power cabinet is connected to the input line with the normal rated voltage,
and the load switch, residual current protector, circuit breaker and other components can be switched
off in turn. The circuit breaker should be correctly switched off.
After the GGF series isolation power cabinet is powered on, check whether the display data of the
instrument on the cabinet is normal. The total inlet line measurement can indicate the current voltage
and current value (GGF-O series cabinet); Insulation monitoring instrument should show the current
IT system insulation resistance value, and no alarm feature.
After the above confirmation, the GGF series isolation power cabinet can be put into use.
In the process of use, if the external alarm display instrument is found to emit abnormal alarm, you
can find the corresponding isolation power cabinet according to the alarm information, confirm the
alarm type, and then carry out load disconnection operation until the insulation monitor recovers
normal.
