Technical
Installation
Flush mounting steel wall box
It should be noted that some of the conduit entries may be restricted,
depending upon their positions and the depth of box used.
Socket Testing
Single Socket Testing
After installation, turn the mains electricity supply on.
To test that the Sentrysocket is functioning correctly:
1.
Ensure that no appliance is connected to the Sentrysocket.
Switch Sentrysocket on
: The switch should remain closed
and the red flag will appear in the window. If the switch fails to
remain closed, check that the Supply L and N connections are
not reversed or the Supply N connection is not open circuit. If
the Sentrysocket is correctly connected and still trips after being
switched on, the Sentrysocket is faulty and should not be used.
2.
If the Sentrysocket stays on,
press the test button
: The
switch will open and the white flag will appear In the window.
If the Sentrysocket does not trip and there is mains voltage
present at the socket outlet, Sentrysocket is faulty and should
not be used.
3.
Switch Sentrysocket on
: Connect an RCD tester and ensure
that the Sentrysocket trips within the specified time:
≤ 200 ms AT RATED TRIP CURRENT
≤ 40 ms AT 5 x RATED TRIP CURRENT
If the Sentrysocket does not trip within the specified times then
the product is faulty and should not be used (If more than one
RCD is in series then there is no guarantee as to which device
will trip first).
4.
Reset all tripped RCD’s including the Sentrysocket
.
5.
Switch off the mains supply switch disconnector
. On mains
failure, a Sentrysocket with Active Control Circuit will trip, whilst
a Sentrysocket with Passive Control Circuit will not trip. If the
Active Control device does not trip, it is faulty and should not
be used – see note below. If no faults have been found then
installation testing has been completed successfully.
Note: If a fault is identified at any stage of installation testing procedure do
not use Sentrysocket, and contact your local electrician, or your local MK
stockist.
Sentrysocket
Double Socket Testing
After installation, turn the mains electricity supply on.
To test that the Sentrysocket is functioning correctly follow the
steps 1 to 4 below:
1.
Ensure that no appliance is connected to the Sentrysocket.
2.
Reset
– Press the button marked R (for Reset) – the contact
status indicator should show red, indicating that the socket
outlets are now live (if the switches are in the ON positions).
3.
Test
– Press the TEST button marked T (for Test), the product
should trip with the contact status indicator showing black. In
this state the socket outlets are disconnected from the supply.
4.
Reset
– Press the button marked R again, the contact status
indicator should show red.
5.
Connect an RCD Tester to either socket outlet and ensure that
the Sentrysocket trips with the specified times below:
≤ 200 ms AT RATED TRIP CURRENT
≤ 40 ms AT 5 x RATED TRIP CURRENT
6.
Reset the Sentrysocket as in step 2 above.
7.
Switch off the Mains Supply Switch Disconnector.
8.
A Sentrysocket with Active Control Circuit should trip while a
Sentrysocket with Passive Control Circuit should not trip.
If all the operations in steps 2 to 8 above give correct results, the
Sentrysocket RCD socket outlet is safe to use.
If the procedures in steps 2 to 8 above are not completed
correctly, do not use the Sentrysocket product and seek
professional advice or contact the MK Technical Sales and
Service department on +44 (0)1268 563720.
