1. Precaution
1.3. Ground
The product must be grounded to protect it from static electricity and other dangers. When using a multitap, please use a
multi tap with a ground terminal only.
If you use a 220V wall outlet with a ground terminal, you do not need to ground it additionally. Avoid using wall outlets if
they are not grounded even if they have a ground terminal.
To ground the product, connect the ground to an exclusive ground terminal or metal water pipe. Connect the ground cable to
the ground terminal at the rear of the main body. To ground the product, connect the ground terminal of the product to a
metal water pipe, wall outlet or exclusive ground terminal with an electric wire equal to or thicker than #18.
Never ground the product to a PVC water pipe, phone line, TV, radio antenna, aluminum window or gas pipe, because this
does not actually ground the product and may be dangerous.
