4 Function and device design
4.1 Function
The explosion proof combination signal series YA60 provides an audible 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 B, C, D, Class II Division I Gas groups E, F, G.

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

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.

8.2.3 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.
8.2.4 Electrical Connection
Key Components
• 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.

Cable Connection
Interconnection of YA60 units parallel
Up to 10 YA60 devices with common supplies may be connected as a single system loop.
See wiring diagrams for further information.
Circuit diagrams
YA60 DC voltage variants
Approximately 20 cm (8 Inch) tails are required inside the enclosure for
connection 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.
Line monitoring for devices with DC
• using power supply reversal
• by connecting an EOL resistor between 0 V and +V. The resistance val-
ue is defined by the system developer.
Two signal levels for devices with DC
• using power supply reversal
• by connecting the third wire.
Two signal levels for devices with AC
• by connecting the third wire.
