Intended use
2 INTENDED USE
Improper use of the Type AC10 solenoid may be dangerous
to people, nearby equipment and the environment.
The TypeAC10 solenoid is used to operate valves that
control gaseous or liquid media.
▶A valve operated with the Type AC10 solenoid is to be used
exclusively with the permissible media specied in the data
sheet and for use in explosion group IIC, category 3G and/or
explosion group IIIC, category 3D and temperature class T4
(see details on the type label for the Ex area).
▶The solenoid may only be used for the applications specied
in chapter „5 Operational conditions of the devices“ and in
connection with the Type 2509 or Type 2513 cable plugs
available from Bürkert.
Variants with UL listing are only authorised for Type 2509
cable plugs.
▶Prerequisites for safe and trouble-free operation of the
device are proper transport, storage and installation as well
as careful operation and maintenance. Any other or addi-
tional use is not considered part of the intended use. Bürkert
will not be liable for any damage resulting from this. The user
alone bears the risk.
▶Only use the device as intended.
2.1 Ex approval
The explosion protect approval is only valid if you use the modules
and components authorised by Bürkert as described in these oper-
ating instructions. The Type AC10 solenoid with Type 2509 or Type
2513 cable plug may be used only in combination with the additional
components approved by Bürkert, otherwise the explosion pro-
tection approval is terminated. In the event of unauthorised changes
to the device, modules or components, the explosion protection
approval is also void. The EU type approval test certicate and the
following IECEx certicates have been issued by:

3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not take into account any
unforeseen circumstances and events which occur during instal-
lation, operation and maintenance.
The operator is responsible for observing the location-specic
safety regulations, also with reference to personnel.
Risk of injury due to high pressure in the system or device.
▶Before working on the system or device, switch o the pres-
sure and ventilate or empty the lines.
Risk of injury due to electric shock.
▶Before working on the system or device, switch o the
power supply and secure against reactivation.
▶Observe the applicable accident prevention and safety regu-
lations for electrical devices.
Risk of burns or re from hot device surfaces due to prolonged
operation.
The solenoid can become very hot during continuous operation.
▶Keep the device away from highly ammable substances
and media and do not touch with bare hands.

Basic safety instructions
Risk of explosion.
Solenoids and valve bodies form a closed system after instal-
lation. When used in a potentially explosive atmosphere, there is a
risk of explosion when the system is opened while in operation.
▶Do not dismantle or open the system during operation.
Risk of explosion due to electrostatic discharge.
If there is a sudden discharge of electrostatically charged devices
or people, there is a risk of explosion in the Ex area.
▶Use suitable measures to ensure that electrostatic charges cannot
occur in the Ex area.
▶The device must not be used in areas with processes that
generate heavy charges, involve automated grinding or cut-
ting, the spraying of electrons (e.g. near electrostatic painting
equipment) or generate pneumatically propelled dust.
▶Clean the device surface by gently wiping it with a damp or
anti-static cloth only.
To avoid the risk of explosions, the following must be observed
in the Ex area:
▶Information about temperature class, ambient temperature,
degree of protection and voltage on the type label for the Ex
area.
▶Installation, operation and maintenance may only be per-
formed by qualied personnel.
▶Observe applicable safety regulations (as well as national
safety regulations), as well as the general rules for the tech-
nology during setup and operation.
▶Repairs may only be carried out by the manufacturer.
▶Do not subject the device to mechanical and/or thermal
stresses which exceed the limits described in the operating
instructions.
▶Do not disconnect connector while circuit is live.
General hazardous situations.
To prevent injuries, observe the following:
▶Secure the device or system against unintentional activation.
▶Note the ow direction when installing.
▶Following an interruption in the power supply, ensure that
the process is restarted in a controlled manner.
▶Do not use the device as a lever when screwing the valve
into the line.

5 OPERATIONAL CONDITIONS OF
THE DEVICES
5.1 Special conditions
▶Only use the device in an area which has pollution degree2
at least, as dened in IEC60664-1.
▶Ensure that the transient protection has been set to a value
which does not exceed 140% of the rated peak voltage
value on the supply connections of the device.
▶Use the device only in a mounting position that is not subject
to mechanical stress.
Installation advice
The information for the authorised ambient temperature con-
cerns the single installation of the solenoids. If multiple sole-
noids are installed in one valve block:
▶Prevent mutual heating by using a suitable distance.

Operational conditions of the devices
WARNING!
Hazard due to electrostatic discharge.
If there is a sudden discharge of electrostatically charged
devices or people, there is a risk of explosion in the Ex area.
▶Use suitable measures to ensure that electrostatic charges
cannot occur in the Ex area.
▶The device must not be used in areas with processes that
generate heavy charges, involve automated grinding or cut-
ting, the spraying of electrons (e.g. near electrostatic painting
equipment) or generate pneumatically propelled dust.
▶Clean the device surface by gently wiping it with a damp or
anti-static cloth only.
5.2 Operating conditions
The valve fulls a cooling function for the solenoid.
The solenoid must not be operated without a valve. The valve
body must meet the following prerequisites:
• Material
Metal (brass, aluminium, stainless steel) or polyamide
• Minimum dimensions
32mmx32mmx10mm
A larger valve body with better thermal conductivity may be used
at any time.
Solenoids intended for single installation must not be used for
block installation.
5.3 Operating temperature range
Pay attention to the operating temperature range for each type
listed in the electrical data.
