arm
(See "Figure 9")
Follow the safety instructions
Follow the general safety instructions prescribed in
“Chapter 8.1” on page 80
.
1. Check whether the end device (e.g. OR lamp) on the spring arm 4 can now be ro-
tated more than 360degrees.
• If this is the case, an internal 3-, 5- or 7/9-pole plug coupling 4-6 has been mounted
and the end device (e.g. OR lamp) may be dismantled by you as a technician author-
ised by the operator.
Sudden release of spring arm
The spring arm 4 contains a powerful spring. When the end device (e.g.
OR lamp) is dismantled, the spring arm can suddenly jump up and may
cause serious injury:
• Before removing the end device (e.g. OR lamp), make sure that the
vertical lift of the spring arm 4 as described in
“Chapter 9.4.1” on
page 100
is restricted to the lowermost end stop (horizontal position).
2. Restrict the vertical lift of the spring arm 4 to the horizontal position as described in
“Chapter 9.4.1” on page 100
.
➥ It must no longer be possible to move the spring arm 4 upwards beyond the hori-
zontal position.
3. Unscrew the sleeve securing screw M3 x 8mm 2 and push the sleeve 1 upwards.
4. To relieve the securing segment 3 slightly lift the end device and remove it using a
suitable slotted screwdriver.
NOTE – Different plug couplings
Depending on the version of the end device (e.g. OR lamp), the spring arm 4 is equipped
with a 3-, 5- or 7/9-pole plug coupling.
For the 3-pole 4 and 5-pole plug couplings 5 only:
• Carefully remove the end device (e.g. OR lamp) from the spring arm 4, keeping it
straightly aligned.
For the 7/9-pole plug coupling 6 only:
• Carefully remove the end device (e.g. OR lamp) from the spring arm 4, keeping it
straightly aligned.
• Screw the 3 plug adapters 8 apart, disengage the 6-pole plug 7 and remove the end
device (e.g. OR lamp).
5. Insert the securing segment 3, push the sleeve 1 downwards and screw the slee-
ve securing screw M3 x 8mm 2 back in.
Marking
If you do not mount another end device (e.g. OR lamp) directly after dismantling, the plug
coupling in the spring arm 4 is energised whilst the mains supply is switched on.
1. Mark the mains supply in the room with a warning sign:
ELECTRIC SHOCK HAZARD – DO NOT SWITCH ON THE POWER SUPPLY!
2. Mount the end device (e.g. OR lamp) later as described in
“Chapter 8.4” on page 86
.
