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 P631 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 P631. Schneider
Electric strongly recommends that these output relays are hardwired into the
substation's automation system, for alarm purposes.
Any modifications to this P631 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 P631 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 P631.
The User should be familiar with the warnings in the Safety Guide
(SFTY/4LM/J11 or later version), with the warnings in Chapter 5, (p. 5-1),
Chapter 10, (p. 10-1), Chapter 11, (p. 11-1) and Chapter 12, (p. 12-1)
and with the content of Chapter 14, (p. 14-1), 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 P631
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).
