INTRODUCTION

Thank you very much for purchasing Edwards’turbomolecular pump.

The turbomolecular pump is designed to be installed in the vacuum equipment to exhaust

gases from it.

This manual covers all items necessary to ensure safe installation, operation and

maintenance of the following series of the turbomolecular pump:

Model Name Specification

•STP-301H High-vacuum type

•STP-451H High-vacuum type

•STP-L301H Low-vibration type, High-vacuum type

•STP-L451H Low-vibration type, High-vacuum type

For the specifications of other models, contact Edwards.

In this manual, the above STP pump series is collectively called the "STP pump".

This manual picks up the points of difference between the STP-301/451 series and

STP-301H/451H, the STP-L301/L451 series and STP-L301H/L451H. For the "Safety

Precautions", installation, operation and maintenance, read the "STP-301/451 Series

Instruction Manual" or "STP-L301/L451 Series Instruction Manual".

The points of difference are as follows:

1 "CON4" Connector

STP-301H/451H and STP-L301H/L451H include "CON4" connector as standard equipment.

Refer to Section 7, "How to Start/Stop the STP Pump" and Section 8, "Remote Input/Output

Signal Terminal Block" in "STP-301/451 Series Instruction Manual" or "STP-L301/L451

Series Instruction Manual".

2 Installation of the Chassis (Optional Accessory)

The size of the STP control unit attached to the chassis that is full-rack size is the same as

that of STP-300H.

2.1 Name and Function Each Part

(1) Distribution Cable for Power

⚫For distribution of power

(2) AC POWER Connector

⚫For primary power input.

⚫Power cable for STP-300H can be connected to this connector.

2.2 Attaching the Chassis Front Panel to a Rack

The dimensions of the chassis front panel conform to EIA Standard. Therefore, this panel can

be attached to any type of commercially-available racks.

Attach the front panel unit to the rack according to the following steps:

•Attach the front panel to a rack using the screw holes for the front panel.

•Also support the chassis from the bottom using a support angle or a similar tool.

•To protect the chassis during transport, remove the rubber foot from the bottom and

attach the chassis to the rack using the screw holes for the rubber foot.

◇The chassis cannot be supported with only the screws on the front panel (the

STP control unit and chassis are heavy products).

Always support it from the bottom.

◇When installing the STP control unit and chassis, DO NOT block the ventilation

port of the STP control unit by the support angle or other things. It causes the

control unit to overheat.

◇For the dimensions of the front panel and positions of screw holes for the rubber

foot, see "External Appearance of the chassis (with STP Control Unit)".

◇Confirm the power voltage on the name plate.

◇Connect the primary power cable securely to prevent incorrect wiring.

◇DO NOT apply surge voltage exceeding 1kV to the input power line.

◇Always ground the primary power cable to prevent electric shock.

◇Allowable input voltage fluctuation is -/+ 10 %.

◇A Power cable is not included with shipment. Use the power cable for

STP-300H.
