Electrical potential of lower than 150V
Electrical potential of higher than
150V
Note 1) Grounding work 3
• Grounding must be done by your installation specialist .
• Check if the grounding resistance is lower than 100Ω . When installing a circuit breaker that can cut the electric circuit in
case of a short circuit, the allowable grounding resistance can be 30~500Ω .
Note 2) Grounding at dry place
• The grounding resistance is should be lower than 100Ω . (It should not be higher than 250Ω)
❋ ❋ Examples to use cable striper
<Cable striper>
1 . Adjust the blade position by coin(the controller is at the bottom side of the tool) . Fix the
blade position according to the outer sheath thickness of the power cable .
2 . Fix the power cable and tool by using the hook at the top side of the tool .
3 . Cut out the outer sheath of the power cable by revolving the tool in the direction of the
arrow, two or three times .
