4 Function and device design
4.1 Function
The explosion proof combination signal series YL60 is an audible and visual signal.
It provides an audible and/or visual signal intended to alert, warn or draw attention to an
event. It is designed for use in hazardous or harsh environments. In hazardous areas the
devices have explosion protection for ATEX / IECEx Zones 1 & 2 for gas and 21 & 22 for
dust. Gas groups covered are IIB & IIB + H2, dust protection for IIIC.
UL certified variants offer protection to Class I Division I Gas groups BCD,
Class II Division I Gas groups EFG.
The device is not intended for continuos use.
The life of the xenon flash tube is guaranteed for the following number of flashes:
DANGER
Explosion hazard due to improper use!
Non-compliance results in severe or fatal injuries.
• Use the device only according to the operating conditions described in

7.2 Mounting / dismounting, operating position
• Mount the device on a flat surface suitable for its weight.
• The tone output should be directed towards the area to be covered
(see chapter Technical Data, Polar diagram).
• Insert the cables using certified and flameproof cable glands which are suitable for the
gas group.
• Close unused entries using certified and flameproof stopping plugs.
7.2.1 Installation conditions for electrical connection
DANGER
Risk of explosion!
Risk of injuries and material damage!
• Terminal sleeves are fitted, they must be gas-tight and applied with a
suitable tool.
DANGER
Explosion hazard!
Risk of injuries and material damage!
• Carefully remove or replace the components.
• Exposed joint surfaces must not be damaged and must be protected
from dust and dirt.
• Install the end flanges squarely without applying any force. Do not use
a hammer or other tools when working on the flanges and do not use the
fixing screws to pull down the flanges.
DANGER
Explosion hazard!
Risk of injuries and material damage!
• Only use cable glands with corresponding certificate. The cable glands
must be flameproof (Ex d) and suitable for the type of cable used.
• Close unused open holes in the enclosure with flameproof stopping
plugs.
• Close unused cable glands using flameproof plugs.
• Cable glands, stopping plugs and plugs must meet the requirements of
IEC/EN 60079-14.
• Installation of the cable gland must be performed in accordance with the
manufacturer's instructions.
• Cable entry temperature may exceed 70 °C.
• To ensure degree of protection IP 66, a non-hardening sealant must be
applied to the threads.
DANGER
Danger due to energised parts!
Non-compliance results in severe or fatal injuries.
• Before opening and dismounting the device, disconnect it from the
power supply.
• Secure the device against unauthorized switching.

7.2.3 Reassembly of enclosure
Inserting the PCB
For correct positioning of the PCB there are 2 grooves in the enclosure.
Depending on the version, insert the PCB in the corresponding groove!
• Carefully insert the connected printed circuit board.
• Connect the horn flange to the printed circuit board.
• Set the horn flange on the enclosure. Do not clamp in any cables in the process.
• Insert the horn flange in a straight position without applying any pressure.
• Replace cheese-head screws M5 x 16 (see information below) and tighten the screws
with a tightening torque of 3 Nm.
• Re-attach the cover. Tighten the ST 4.2 x 13 screws with a tightening torque of 0.4 Nm.

• YL60/./F50/./..
• YL60/./L50/./..
• YL60/./N50/./..
• Carefully assemble the device to ensure that the degree of protection
is IP 66.
• The cheese-head screws are delivered with Nyltite seals
(see the "Connection" section above).
• Check the Nyltite seals for damage before the installation.
• Tighten cheese-head screws with a torque of 3 Nm.
• Use the Nyltite seal a maximum of five times with the tightening torque.
