alarm light is on, the connection is in reversed-phase. Disconnect the power
supply and exchange the two lines out of three on the power supply side.

Connect cooling water tube to MP-300K
NOTE:
Depending on water quality, scale might accumulate inside cooling water
tube, or the tube might be corroded. It is recommended to use water circulation
system when there is such concern.
1) Connect the attached cooling water joint to the cooling water IN and OUT
connectors. The screw size of the connector is R3/8. Place seal tape on the
screw part.
2) Connect the cooling water joint to the cooling water supply side.
3) Connect the cooling water hose to the water supply side and the MP-300K water
IN connector, and water discharge side and MP-300K water OUT connector.
4) When the connections are made, open the main valve of cooling water supply to
check that the water flow is correct and no leak is seen in the coupling or hoses in
the joint part of couplings or hose.
5) When you use cooling water circulation system, set the water temperature at
20°C.
Do not connect the earth wire to the power supply line. It may lead to electric shock or
electric leakage.
WARNING
When multiple devices run on one power source, total capacity must be observed
carefully. Overcurrent (voltage drop) by lack of capacity may damage the equipments.
CAUTION
When extension of power cable is needed, the work must be performed by a personnel
who has sufficient knowledge and skill on power connection or cable selection.
