1. GENERAL
This device is suitable for indoor and outdoor use and
damp use.
This equipment is suitable for use in Class I, Division 2,
Groups A, B, C & D Hazardous Locations or non-
hazardous locations only.
WARNING – Explosion Hazard – Do not disconnect
while the circuit is live or unless the area is known to be
free of ignitable concentrations.
WARNING – To prevent the ignition of hazardous
atmospheres, clean with damp cloth.
WARNING – Explosion Hazard – Substitution of any
components may impair suitability for Class I, Division 2.
Application
Hazardous areas often require the use of optical
signals for warning, information or signaling purposes.
The Expertline-LED provides these signalling options.
This equipment is suitable for Class I, Division 2, Groups A,
B, C, D or non hazardous locations only. This device is suit-
able for indoor use and outdoor damp use.
Units are available for operation on 24 VDC and 120-240 VAC,
50/60 Hz.
The available operating modes are Continuous Light, Strobe
Light, Blinking Light and Rotating Light. The device is factory
-set to the operating mode Strobe Light.
Turning on the supply voltage activates the device.
The Expertline-LED is equipped with high brightness LEDs
and comes in the colors red and yellow.
Design
All outer fixing parts have been made of non-corrosive
materials. The stable, all-plastic enclosure complies with
the requirements of type rating 4X, which means the device
can be installed both indoor and outside.
Mounting
NOTE: The mounting surface must be able to support
3.1 Ibs. The device may be placed in any position. For
mounting dimensions, see the dimension illustration. Mount
the Expertline-LED on the wall using four ¼-inch screws or
#14 wood screws of the appropriate length, depending on
the mounting surface.
CAUTION: Equipment damage. Ensure that the con-
duit has been secured to 200 in-lbs (22.6 Nm). Do not
overtighten as it may cause the enclosure to fracture.
Electrical Connections
CAUTION: Equipment damage. Damage will result if
the voltage ratings are exceeded.
Remove the two screws in the cover using a size 4 Allen
key. Bring cable into the enclosure through the conduit ent-
rance and connect the wires to the terminals. Observe the
polarity of the connections for the DC-version. Close the
enclosure and tighten the screws with a torque of ~8.8 in-lbs
(~1 Nm).
Setting the operating modes
The operating modes are set using the four slide switches in
the terminal room (see page 4).
The following operating modes may be set:
• Strobe light only switch 1 to ON
• Blinking light only switch 2 to ON
• Rotating light only switch 3 to ON
• Continuous light 1 only switch 4 to ON
• Continuous light 2 no switch to ON
If more than one switch is set to ON, then the operating
mode Strobe Light is activated.
Warning!
To avoid the danger of the conductors being squeezed, they
should not be laid across the threaded lid bolt or the edge of
the seal.
Maintenance
The Expertline-LED is maintenance free. Nevertheless in case
of dirtiness it should be cleaned from time to time with a
damp cleaning cloth. Never use sharp objects for cleaning.
Waste disposal
The Expertline-LED may be completely recycled as electronic
waste. Upon disassembling, the plastic, metal and electronic
components must be disposed separately. In every single
case the local requirements and regulations for waste disposal
must be observed.
