RBU100H operation manual 1 Safety precautions
-2-
1.3.1 Delivery and installation
Please install the RBU on fire-retardant material.
Do not operate on the RBU if there is any damage or components loss.
Do not touch the RBU, internal components and PCB board after wiring;
otherwise electric shock may occur due to the present high DC voltage.
Note:
Select appropriate moving and installing tools to ensure a safe and normal running of the RBU
and avoid physical injury or death. For physical safety, the erector should take some
mechanical protective measurements, such as wearing exposure shoes and working uniforms.
Ensure to avoid physical shock or vibration during delivery and installation.
Do not carry the RBU by its cover. The cover may fall off.
Install away from children and other public places.
The RBU cannot meet the requirements of low voltage protection in IEC61800-5-1 if the sea
level of installation site is above 2000m.
Please use the RBU in proper environment.
Avoid any conductive objects on the front cover, otherwise electrical shock may occur.
Tighten up the screws when wiring, otherwise fire, leakage current may occur.
1.3.2
Commissioning and running
Disconnect all power supplies applied to the RBU before the terminal
wiring and wait for at least the designated time after disconnecting the
power supply.
Only
qualified electricians
are allowed to operate on the RBU.
Inspect the wiring before running.
Do not touch the terminals of control board when power on.
Before running, ensure the master/slave selection and voltage class
setting are correct.
Adjust and inspect the RBU only after the power indicator is totally off
and the RBU DC bus voltage is measured to be lower than 36V by a
multi-meter.
Do not touch any internal components during the running.
The RBU is an accessory device of the variable-frequency drive (VFD).
Before the use, install a special fuse for semiconductor. Otherwise, in
addition to the RBU failure, the VFD failure or damage may result. No
matter whether the VFD fault is related to the RBU, we are not
responsible for any VFD fault. Please install semiconductor fuses.
