ULVAC CRYOGENICS INCORPORATED

Power-supply connection of EMP-14A
(1) Use tools such as circuit tester to check that the supply voltage is within the
appropriate range as described in “5. Utilities”.
(2) Connect the crimping terminal side of power cables to EMP-14A through the
holes on the bottom. Connect the cables that have matching marks on the
terminal block (R, S, T, E). If the connection is inadequate, it may result in
incidents such as a fire while EMP-14A is in operation.
(3) When the connection to the terminal board is made, attach the power cable
to the circuit breaker and supply electricity by turning on the breaker in the
electric circuit part of EMP-14A. Be sure to confirm that the power is
supplied to the sequencers or other parts in the electric circuit of EMP-14A.
Ensure that main power source is disconnected before making the connection to
power-supply.
WARNING
CAUTION
Only the personnel who have sufficient knowledge and skill on electric connections or
cables can perform the work to extend power cables.
Do not connect the earth ground wire to power lines. It may result in electric shock or
electric leakage.
WARNING
When you operate multiple devices with one power source, be aware of the total
capacity. Lack of capacity invites overcurrent (voltage drop) and may result in the
equipment failure.
CAUTION
