Preface

graphics/symbols/Warning.png WARNING

⚫

When electrical equipment is in operation dangerous voltage will be present in certain parts of the equipment. Failure to observe warning notices, incorrect use or improper use may endanger personnel and equipment and cause personal injury or physical damage.

Before working in the terminal strip area, the P632 must be isolated. Where stranded conductors are used, insulated crimped wire end ferrules must be employed.

The signals MAIN: Blocked/faulty and SFMON: Warning (LED) (permanently assigned to the LEDs labeled OUT OF SERVICE and ALARM) can be assigned to output relays to indicate the health of the P632. Schneider Electric strongly recommends that these output relays are hardwired into the substation's automation system, for alarm purposes.

Any modifications to this P632 must be in accordance with the manual. If any other modification is made without the express permission of Schneider Electric, it will invalidate the warranty, and may render the product unsafe.

Proper and safe operation of this P632 depends on appropriate shipping and handling, proper storage, installation and commissioning, and on careful operation, maintenance and servicing.

For this reason only qualified personnel may work on or operate this P632.

The User should be familiar with the warnings in the Safety Guide (SFTY/4LM/J11 or later version), with the warnings in Chapter “Installation and Connection”, Chapter “Commissioning”, Chapter “Troubleshooting” and Chapter “Maintenance” and with the content of Chapter “Accessories and Spare Parts”, before working on the equipment. If the warnings are disregarded, it will invalidate the warranty, and may render the product unsafe.

Installation of the DHMI:

A protective conductor (ground/earth) of at least 1.5 mm² (US:  AWG14 or thicker) must be connected to the DHMI protective conductor terminal to link the DHMI and the main relay case; these must be located within the same substation.

To avoid the risk of electric shock the DHMI communication cable must not be in contact with hazardous live parts.

The DHMI communication cable must not be routed or placed alongside high-voltage cables or connections. Currents can be induced in the cable which may result in electromagnetic interference.

Qualified Personnel

are individuals who

▪	are familiar with the installation, commissioning and operation of the P632 and of the system to which it is being connected;
▪	are able to perform switching operations in accordance with safety engineering standards and are authorized to energize and de-energize equipment and to isolate, ground and label it;
▪	are trained in the care and use of safety apparatus in accordance with safety engineering standards;
▪	are trained in emergency procedures (first aid).

Note

This operating manual gives instructions for installation, commissioning and operation of the P632. However, the manual cannot cover all conceivable circumstances or include detailed information on all topics. In the event of questions or specific problems, do not take any action without proper authorization. Contact the appropriate technical sales office of Schneider Electric and request the necessary information.
