1. SAFETY INSTRUCTIONS
The following instructions are related to human safety, please read them carefully!
1.1 Human Safety
There is high voltage inside the running voltage regulator, in order to avoid electric
shock, do not open the voltage regulator or take off the input wires and output wires.
The connection wires must be laid reasonable. It may cause electric accident due to
the wires are trampled.
The voltage regulator must be connected to the ground. Grounding resistance must
be less than 0.1 MΩ. Without ground connection or improper ground connection can
be dangerous for human safety, and also can cause high risk of electronic circuit
board faults.
Never connect the ground wire to the conduit of central heating system, gas supply
system, water supply system, or any other public utilities.
1.2 Installation and Operation
Keep the package for future moving or repairing.
Keep far away from wall and flammable material.
Do not block the cooling holes of the voltage regulator.
Make sure all the wires are well and tightly connected, not loose or disconnected.
The ground wire and neutral wire can't be reversely connected, otherwise it may
damage the voltage regulator or cause electric shock.
The live wire and neutral wire can't be reversely connected.
For three phase voltage regulator, the maximum power capacity of each phase is
1/3 of the full rated capacity.
Do not use the voltage regulator in damp environment.
Do not drop any foreign material (like clips, nails, etc.) into the voltage regulator.
In emergencies (damage to the cabinet ort o the connections, splashing of liquid,
drop of any foreign material into the voltage regulator), please switch it off,
disconnect the wiring connection from the mains power and from the loads, then
contact the authorized dealer.
In the event of sudden temperature changes such as from cold to the normal working
temperature, mist can form inside the voltage regulator. The voltage regulator must
be dry before being switched on. Due to this reason, wait for at least 2 hours before
switching it on.
The voltage regulator can only be repaired by the authorized technical person. Any
attempt to open and to repair it by the user on his own could prove to be dangerous.
Placing magnetic storage media on top of the regulator may result in data corruption.
1.3 When Input Comes From Generator
The capacity of the generator must be biggerthan the rated capacity of the voltage
regulator, otherwise the generator and voltage regulator can't work properly.
The output frequency of the generator must be within 45-65Hz. And the generator
should has sine wave output, otherwise the regulator can't work properly.
