5.
When the arrows and dots are not visible then check
the operation of the voltage detection using the
voltage detection tester (18) see Figure 4-9:
a. insert the tester plugs in the contact sockets
“earth” and L1. Test the detector by pressing the
tester button.
The tested phase arrow and dot should now be
present;
b. repeat the test for L2 and L3.
c.
if one or more arrows and dots do not appear, this
might be the result of a faulty voltage detector.
Should this be the case contact Eaton. Ensure by
other means that the cable is dead before carrying
out any further switching operations.
6.
When the arrows and dots are visible then the
functionality of the voltage detector can be tested as
follows:
a. Connect a wire from the tester between the
contact sockets “earth” and L1. The arrow and dot
indication from this phase must disappear.
b. Repeat this test with the phases L2 and L3.

OTE
The detector also has a piezo test button on the
front for testing the LCD screen only.
7.
Earth the cable by turning the switch ON. Insert the
operating handle with the arrow pointing up in the
switch control point. Turn the handle 190
0
clockwise.
You will hear the mechanism switch. Remove the
operating handle. The cable is now connected to
earth.
8.
Put the selector in the central position so that both
control openings are covered.
The integrated earthing of the Xiria panel is now ON; the
cable is earthed to be short-circuit proof through the switch.
The earthed position can now be locked as described in
par. 4.3.2.
Procedure for switching cable earthing off
1.
Check whether the cable earthing can be switched off.
2.
Remove the padlock from the earthed position
interlock (if it is still in place), as described in
par. 4.3.2.
3.
Switch OFF the switch of the relevant panel with push
button (3).
4.
Check that the position indicator on the switch (4)
indicates the OFF position.
5.
Rotate the selector (7) back to the central position;
both openings will be covered.
The panel is back in the neutral state:
switch OFF;
change-over switch to earth.
4.2.3
Gaining access to cable
N
OTE
When gaining access to the cable, the following
basic rules apply at all times:
•
Disconnect the cable at both ends.
•
The panel must be in the closed earthed
position.
•
Secure this internal earthing by locking it with a
personal padlock.
•
Verify that the cable can never be made live from
the other end.
•
On request a visible back-up earth can be
installed in accordance with the cable plug
supplier's instructions.
