Field of use
• In assembled state with cover fitted, the signalling column complied with
Degree of Protection IP 65!
• In order to maintain shock-hazard protection (VDE 0106) on the part of the
terminals, proper connection of the live conductors to these terminals is
essential!
• The signalling column is constructed and tested in accordance with
DIN VDE 0660. To ensure safe operation, the following notes should be
observed:
At close range, the sound pressure of the audible signal
devices is capable of causing damage to human hearing.

General principle of operation
The signalling column converts electrical signals into:
• Visible signals (steady light, LED steady glow
, flashing light ,
blinking light , LED blinking light , LED occulting light )
and/or
• Audible signals (buzzer , siren )
When mounting, ensure that there is a flat, level surface (sealing!) and ade-
quate space for the complete signalling column. The accessories are fitted
using M4 screws. For hole spacing, please see the diagrams
(Fig. I, IIIa, IIIb)
or the dimensions given on the bottom of the fixing elements Ä / Å / É / Ê ).
Methods of fixing
There is a choice of the following types of mounting:
• Floor and bracket mounting
(Fig. IIf, IIg, IIh)
• Tube mounting (Fig. IIc, IId, IIe)
Mounting the signalling column
• Screw the fixing element - e.g. base with integrated tube for tube moun-
ting Ä (Fig. IIc, IId) , base Å with tube Æ for tube mounting (Fig. IIe) ,
bracket for pedestal mounting Ç (Fig. IIf) , bracket for base mounting È
(Fig. IId) , bracket for one-sided pedestal mounting É (Fig. IIg) , bracket
for two-sided pedestal mounting Ê (Fig. IIh) , collar for side entry of cable
Ë (Fig. IIe) , collar for side entry of cable with magnet Ì (Fig. IIc) - onto
the unit (please refer to the hole diagrams (Fig. I, IIIa, IIIb) or the dimen-
sions given on the bottom of the fixing elements Ä / Å / É / Ê ).
• Introduce the cable through the fixing element and connecting element ¿
from below (Fig. IIIc) .
• To reach Degree of Protection IP 65 place gasket (if enclosed) between
fixing and connection element.
• Connect the cable (Fig. IIId, IIIe) .
(In the case of Cage-Clamp-connection: Push a screwdriver into the square
opening, insert the conductor into the round opening, and remove
screwdriver).
• Fix connection element
¿ by means of screw A (floor and bracket moun-
ting) or screw B (tube mounting) (Fig. IIIf) .
• Fit an incandescent lamp or LED (bayonet mounting) into the signal ele-
ment (Fig. IIIg) .
• Fit the signal elements.
Fit up to 5 signal elements (4 in the case of AS-i, Fig. IIc ) on each connection
element. The white lines on the base and on the signal element must be lined
up, then turn the element in the direction of the arrow (printed on the signal
element) until it locks into place
(Fig. IVa, IVb , IVc) .
Fit the cover À so that the white line on the signal element lines up with the
left-hand line on the cover. Then turn the cover in the direction of the arrow
until it locks into position
(Fig. IVd) . If you make use of an audible signal
device à (Fig. IIc) , it forms the outer enclosure because it has an integrated
end cover.
General care
Clean the signalling column with a mild detergent which contains no abra-
sive. Do NOT use thinner. Keep away from soluble machine oil!
Maintenance
The signalling column should be removed for the purpose of changing indivi-
dual signal devices or replacing defective bulbs (bayonet fitting). To do this,
twist signal device in the opposite direction to the arrow and lift the device
out.

Applications
WARNING:
• To be connected only by qualified electricians!
• Before you connect the unit or if the unit has been damaged,
make sure that the power has been disconnected first!
• Do not operate the unit unless it has been completely mounted!
• Observe the rated voltage of the signalling column!
Excessive voltages cause damage!
• If failure of the signalling unit might result in personal injury or
damage to the operating equipment, additional protective mea-
sures have to be taken!
