WARNING
A hazardous live voltage may exist at the connectors that are marked .
DO NOT touch the terminal. Doing so may result in electric shock. When
connecting/disconnecting the terminal connections, always power OFF (turn the
MAIN POWER "OFF") and isolate (Lockout/Tagout) the electrical energy source,
water and gas, and other energy sources on the vacuum equipment. Failure to do so
may cause the STP pump to rotate accidentally, which may injure operators
seriously or result in electric shock.
WARNING
DO NOT remove the connecter while the pump is rotating. The voltage might be
output to connector according to the rotational speed, and it causes the electric
shock or the failure.
