4 Installation
WARNING! Risk of personal injury
• The Swing Arm SA-G must be mounted ac-
cording to the installation instructions and
mounted to a wall or to a column with enough
strength to take up the forces caused by the
weight of the arm, permissible extra load,
and the normal use of the arm.
• The band keeping the inner arm and the out-
er arm together, must not be removed until
the installation is finished. The band ensures
the outer arm will not suddenly swing out,
which could cause an accident.
• Work with electric equipment is to be carried
out by a qualified electrician.
4.1 Installation options
See
.
• When mounting to a steel or concrete column the
recommendation is to use alt. 1.
• If mounted to a weak wall, it may be necessary to
reinforce the wall and to use long screws going
through the wall according to alt. 2.
• An extra wall bracket with a larger surface area, in
order to distribute the forces over a large area, is
available according to alt. 3.
• Certain arms may be mounted to the roof according
to alt. 4.
4.2 Mounting
Recommended mounting height and suggested loc-
ation of a possible compressed air outlet is shown in
• Use four screws, M12, for mounting the bracket.
• For concrete, use M12 para bolts (concrete expan-
sion bolts), 110 mm long, for example Hilti HSA
M12x110/15 and a 12 mm drill. (Alternatively, use
1/2" x 4 1/2" bolts, for example Hilti KB II 12-412 and
drill with 1 /2" drill.) torque, 60 Nm or 45 ft. lb. Thin
spacers may be required if the base is not vertical.
• Mounting of the extra wall bracket on concrete re-
quires longer screws. i.e. Hilti HSA M12 x 180/85
{1/2" x 7"), for the upper two holes.
The stop ring and the tension rod are to be mounted
according to
.
• Adjust to a certain pulling force with the nut at the
lower end of the tension rod.
WARNING! Risk of personal injury
• Swing Arm SA-G 600 must never be mounted
without the tension rod.
• It is very important that the stop ring is se-
curely fastened.
Swing Arm SA-G 300 and Swing Arm SA-G 450 may
be mounted without the tension rod if mounted to
the roof and a 360° swing range is required. If a 360°
swing range is not required, mounting of the tension
rod is always recommended.
• Make sure the three stop ring screws are locked
with the nuts after they have been screwed in as far
as possible.
The grounding wire is to be mounted according to
WARNING! Risk of personal injury
Static electricity is often created when
particles pass through a hose at high velocity.
Therefore, the arm must always be grounded
for discharge of static electricity.
1
First cut the vacuum hose to suitable height above
floor level.
2
Peel off the wire plastic coating 40-50 mm in both
ends of the vacuum hose. The coupling is made of
conductive plastics.
3
Turn in the wire at the upper end to make a con-
tact with the arm and with the hose coupling at
the lower end. Twist the coupling counter clock
wise into the hose.
4
Remove any paint or coating for a good contact.
Extend the cable if necessary. The static electri-
city current is very low, a few micro amps. The
mechanical strength of the cable determines the
cable area, 1.5 mm
2
is recommended.
5
Check that the clip fitted to the inner arm is in con-
tact with the outer arm. See
6
Fit supplied grounding cabe to the stop ring and
link the other end (peeled off) to ground.
7
Ensure the arm can swing within the working area
without tearing off the wire. The compressed air
pipe is usually grounded as well as the building
steel construction.
For arms to be fitted with compressed air, mount the
air hose according to
.
• Cut the vacuum hose and the compressed air hose to
a height of 1 -1.5 m above floor level.
NOTE!
A possible electric outlet should also be located
in level with the hose coupling.
• Check that the arm can swing within desired range
without stretching the hoses. An automatic vacuum
valve TAV 50 is often fitted to the wall bracket and
the air hose is then linked to the valve. Otherwise,
