SCU-1601 Control Unit for Turbomolecular Pump
WARNING
When connecting/disconnecting cables, always power off the STP pump (switch the
SCU-1601 MAIN POWER to "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 result in the inadvertent rotation of the STP pump which may result in an
accident, an electric shock or damage to equipment. An accident caused by water leaks
or gas leak may occur.
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.
WARNING
When connecting the wire to the protective earth terminal, use AWG 14 wire with
yellow/green.
CAUTION
Use each cable that Edwards has specified to connect to SCU-1601 and STC-U. The use of other
cables may result in product damage. Align the position of the guide key of the connectors and insert
vertically so as not to bend the pins. If a pin is bent, not only may the connector not function normally,
but it may make the pins contact, resulting in a malfunction. Lock and securely tighten each
connector and screw.
CAUTION
Connect each cable securely with caution, avoiding any obstacles. DO NOT place heavy objects on
the cables or bend them excessively. Support each cable so as not to apply direct force to the
connectors or terminals. If any problem occurs in cables, connectors or terminals, the STP pump
may not function normally. DO NOT apply voltage to each connector pin and DO NOT cause any
short-circuiting between pins. Install cables so that personnel are not exposed to risk of tripping or
falling.
