Use each cable that Edwards has specified to connect to SCU-800/801 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
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 STC-U 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.
Applicable cables for the STC-U depend on the pump specification. Refer to the STP pump
Instruction Manual (B) for the cable connection method.
