3.4.6 How to connect the power cable
WARNING
When connecting/disconnecting cables, always power off the primary power (switch
the 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. Moreover, an accident
caused by water leaks or gas leak may occur.
CAUTION
Use the power cable that Edwards has specified. The use of other cables may result in product
damage.
CAUTION
Confirm the power voltage on the label. Connect the power cable securely to prevent incorrect
wiring.
CAUTION
Connect each cable securely with caution, avoiding any obstacles.
DO NOT place heavy objects on the cables or bend them excessively. 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.
CAUTION
With each connector 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
DO NOT apply surge voltage exceeding 1 kV to the input power line. Always ground the power
cable to prevent electric shock.
