1 Packaging
Relays are supplied in packaging designed to mechanically protect them while in both transit and
storage.
This packaging should be recycled where systems exist, or disposed of in a manner which does not
provide a threat to health or the environment. All laws and regulations specific to the country of
disposal should be adhered to.
2 Unpacking, storage and handling
On receipt, remove the relay from the container in which it was received and inspect it for obvious damage. It is
recommended that the relay modules are 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, also inform Reyrolle
Protection and the nearest Reyrolle agent, using the Defect Report Form in the Maintenance section of this
manual.
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, these devices are susceptible to damage due to static discharge and
for this reason it is essential that the correct handling procedure is followed.
The relay’s electronic circuits are protected from damage by static discharge when the relay is housed in its case.
When individual modules are withdrawn from the case, static handling procedures should be observed.
• Before removing the module from its case the operator must first ensure that he is at the same potential as
the relay by touching the case.
• The module must not be handled by any of the module terminals on the rear of the chassis.
• Modules must be packed for transport in an anti-static container.
• Ensure that anyone else handling the modules is at the same potential.
As there are no user serviceable parts in any module, there should be no requirement to remove any component
parts.
If any component parts have been removed or tampered with, then the guarantee will be invalidated. Reyrolle
Protection reserve the right to charge for any subsequent repairs.
3 Recommended Mounting Position
The relay uses a liquid display (LCD) which is used in programming and or operation. The LCD has a viewing
angle of ± 45º and is back lit. However, the best viewing position is at eye level, and this is particularly important
when using the built-in instrumentation features.
If the LCD appears to be blank, but the Protection Healthy LED is correctly illuminated, the LCD contrast requires
adjustment. To do this:
• Hold down the RIGHT-most key.
• Then hold either the LEFT-most key (contrast raise) or the SECOND LEFT-most key (contrast lower).
