3.2.2 Installation Area
Leave enough space for the following in addition to that for the STP pump:
• Space for maintenance and inspection
• Space for connecting cables
◇ The minimum bending radius of the STP connection cable is
150 mm (See Figures 16.1 and 16.2, "External Appearance of the STP
Pump" [bending dimensions of the STP connection cable]).
DO NOT excessively bend the cables and beware of any obstacles
when installing the STP pump.
Also, leave enough space to install other cables without bending
them excessively.
3.2.3 Bench
A bench must be prepared by the customer to secure the STP pump. The shape
and size of the bench differ depending upon the type of STP pump. Follow the
precautions of the WARNING, CAUTION, or NOTICE (See Section 3.3.3, "How
to Secure the STP Pump").
◇ The STP pump is provided with a high-speed rotor. Any internal
abnormality/error may result in a jump in rotational torque leading to
personal injury or peripheral equipment damage.
Design and secure the bench for the STP pump so that it can
withstand the maximum torque generated due to the occurrence of
an abnormality/error. Refer to Section 3.3.3 "How to Secure the STP
Pump" for abnormal torque.
◇ Secure the customer-prepared bench and the vacuum equipment on
the floor or peripheral equipment and other equipment in accordance
with the customer application. NEVER move them while the STP
pump is in operation.
◇ Use fitting bolts with strength equal to or higher than SUS 304
