7SG11 Argus 8 Installation
1 Unpacking, storage and handling
On receipt, remove the relay from the container in which it was received and inspect it for obvious damage.
Check that the relay is the correct model number and the rating information is correct. It is recommended that
the relay is not removed from the case. To prevent the possible ingress of dirt, the sealed polythene bag
should not be opened until the relay is to be used. If damage has been sustained a claim should immediately
be made against the carrier and Reyrolle Protection and the nearest Reyrolle agent should be informed.
When not required for immediate use the relay should be returned to its original carton and stored in a clean,
dry place. The relay contains static sensitive devices, which are susceptible to damage due to static discharge
and for this reason it is essential that the correct handling procedure is followed. The relays’ electronic circuits
are protected from damage by static discharge when it is housed in its case. When it has been withdrawn
from the case, static handling procedures should be observed.
•
Before removing the relay from its case the operator must first ensure that he is at the same potential as
the relay by touching the case.
•
The relay must not be handled by any of the relay terminals on the rear of the chassis.
•
Relays must be packed for transport in an anti-static container.
•
Ensure that anyone else handling the relays is at the same potential as the relay.
As there are no user serviceable parts in the relay, then there should be no requirement to remove any
modules from the chassis. If any modules have been removed or tampered with, then the guarantee will be
invalidated. Reyrolle Protection reserves the right to charge for any subsequent repairs.
2 Recommended mounting position
The relay uses a liquid crystal display (LCD) which displays setting and metering information. It has a viewing
angle of ± 70º and an internal back light. The recommended viewing position is at eye level.
The relay should be mounted onto the circuit breaker or panel at a level which allows the user easiest access
to the relay functions.
3 Relay dimensions
The relay is supplied in either the Epsilon size E4 case or E6 case. Mechanical diagrams of the case
dimensions and panel cut-out requirements are shown in Figures 1 and 2 respectively.
