INSTALLATION
1. UNPACKING
On receipt, remove the relay from the carton box in which it was received and inspect it
for obvious damage. It is recommended that the relay is not removed from the relay 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, please inform Easun Reyrolle Ltd., for necessary action.
2. STORAGE
When the relay is not required for immediate use, it should be returned to its original
carton and stored in a clean dry place.
3. HANDLING
The relay’s electronic circuits are protected from damage by static discharge when the
relay is housed in its case. When relay is withdrawn from the case, static handling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 at the rear of the chassis.
•
Ensure that anyone else handling the relay is at the same potential.
As there are no user serviceable parts and adjustable user settings inside the relay, there
should be no requirement to remove any modules from the chassis.
If any modules are removed or tampered with, then the guarantee will be invalidated.
4. MOUNTING
Mount the relay using 2 nos. mounting straps and 1no earth strap. Ensure that an earth
wire is connected to the earth strap from the earth terminal 23. Terminal 23 should be
directly connected to the system ground.
Only settings or trip details can be accessed via the pushbuttons when the cover is fitted.
To change the settings the front cover has to be removed. Sealing arrangement is
provided in one of the four knurling screws fitted on the cover. Sealing can be done using
a sealing wire. Thus mechanical interlock is provided to avoid unauthorized setting
change.
