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:

7 Mounting and installation
7.1 Dimensions / fastening dimensions
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.

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.

• Remove the 3 screwST 4,2 x 13
• Lift horn cover
• Remove the 4 cheese-head screws M5 x 16
• Lift sounder flange
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 reach 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!
Risk of death or severe injuries!
• Before opening and dismounting the device, disconnect it from the
power supply.
• Secure the device against unauthorized switching.

• Disconnect pressure unit from PCB (see Electrical Connection, Key Components)
• Lift PCB to expose terminals for connection (see Electrical Connection,
Wiring Diagrams for details)
7.2.3 Reassembly of Enclosure
• With wires terminated, carefully lower PCB back into position.
• Reconnect pressure unit to PCB and place sounder flange back into position.
Take care not to trap connecting wire in the joint. The flange must be inserted squarely
into the main body, do not use force.
• Replace cheese head screws M5 x 16 (see information box below) with 3Nm torque.
• Fit horn cover into position.
• Replace screws ST 4,2 x 13 with 0,4 Nm torque.
• Correct reassembly of the unit is required to ensure ingress protection
to IP 66. Cheese-head screws (see chapter Acess to the PCB, position
3) are supplied with Nyltite washers. Before reassembly inspect Nyltite
for damage and check orientation is correct as per diagram.
• Cheese-head screws should be tightened with a torque of 3 to 3.05
Nom.
• Each Nyltite should not have torque applied more than 5 times.

Approximately 20 cm (8 Inch) tails are required inside the enclosure for con-
nection to the terminals on the PCB. This is especially important for
installation using solid core cable. Care is needed when re-inserting the
PCB.The terminals accept wires of 2.5 mm2 or 14 ... 18 AWG.
