Safety | COIL D36 5/10
2 Safety
2.1 General safety notes and prohibited uses
▶ Comply with the safety and environmental protection standards in force.
▶ Comply with the safety standards and provisions in force in the country in which
the coil is installed/used.
▶ Use Rexroth products only if they are in perfect technical condition.
▶ Comply with the instructions shown on the product.
▶ The person responsible for assembling, using, disassembling or servicing Rexroth
coils must not be under the influence of alcohol, narcotics or medicines that
affect his/her reactions.
▶ Comply with the technical data and ambient conditions specified in the product
documentation.
▶ Ensure the device is cleaned correctly to avoid the accumulation of dust, which
could cause a fire hazard.
▶ Operate this product only if you are sure the end product (machine or plant) in
which Rexroth products are incorporated complies with the provisions, safety
directives, and specific operating standards in force in the respective country of
use.
▶ Do not use the coil in explosive or flammable atmospheres (the module is not
certified to 2014/34/EU ATEX).
▶ Do not use the module in a construction configuration other than the one
specified by the manufacturer.
▶ Do not incorporate other systems and/or equipment not contemplated by the
manufacturer in the construction project.
▶ Do not use the module with the case removed, damaged, or incorrectly closed.
▶ Do not connect the device to energy sources other than those specified by the
manufacturer.
▶ Do not use the device without having first read and fully understood the
instructions for use attached to this technical documentation and supplied with
the module.
▶ Do not use commercial devices for purposes other than those intended by the

▶ Do not carry out maintenance tasks without first appropriately selecting the coil
power supplies.
▶ Do not use the device in the absence of short-circuit protection.

2.2 Improper use and precautions
PRECAUTIONS
High voltage!
On electric coils having power supplies > 50Vac and/or 75Vdc, touching any live
part of the product can result in fatal electrocution.
▶ The coil must be connected by an expert electrician or under the supervision of
an expert electrician.
▶ Before all maintenance, repair, or installation operations, disconnect the power
supply and perform a lock-out/tag-out procedure to prevent reconnection.
▶ Ensure the connection is made correctly and safely.
▶ Use exclusively power supply units with a PELV (Protective Extra Low Voltage)
protection device. Safe interruption can be achieved, for example, by means
of isolation transformers, safe opto-isolators, or battery powered operation
without a mains connection
Electromagnetic radiation!
Because they emit electromagnetic radiation, coils may interfere with other
electronic equipment and also suffer disturbances caused by external
electromagnetic radiation, resulting in possible uncontrolled movements in the
plant.
▶ Do not exceed electromagnetic radiation limit values.
▶ Use exclusively the prescribed connecting cables.
▶ Pay attention to CEM compliant wiring.
▶ Make sure the coils are properly connected to earth.
Burns hazard!
When the coil is supplied with power it is subject to a self-heating effect:
temperature rise of the external parts of the device. Risk of burns if the operator
accidentally touches external parts of the device.
CAUTION
▶ Any use other than that described under intended use is deemed to be
nonconforming use and is therefore prohibited.
▶ Incorrect connection of the coil connector will result in failed excitation and
consequently no displacement of the moving element of the valve.
▶ If the coil is excited using an incorrect power feeding voltage, the result may be
an inappropriate valve reaction followed by possible damage.
▶ If the connector is immersed in liquid it will be damaged resulting in incorrect
operation of the coil.
▶ If the machine manufacturer has not created a protection system, we
recommend installing a fuse up-line from the coil rated at double the maximum
current value the coil is designed to withstand.

Directive.
Figure 1 - WEEE Directive
3.3 Description of operating principle
The current that flows through the coil winding creates a magnetic field. The
magnetic field acts on the solenoid armature and causes it to move, thereby moving
the valve control element (spool, sealing element).
The coil is accommodated in a steel housing, thus amplifying the magnetic field and
protecting the device against mechanical damage.
In addition, the coil is embedded in plastic material to mould it into the housing.
Also the part of the connector coupled to the coil is made of the same plastic
material. A silicone seal protects the coil space from the ingress of moisture and
dust.

4 Assembly and installation
4.1 Assembly information
Comply with following guidelines to ensure correct assembly of the coil. The coil
must be mounted securely to the valve, fitting seals on each side and a nut. The
nut must be tightened to the torque value defined in accordance with the valve
installation context.
Figure 3 - Coil D36 Assembly
Do not use the equipment without short-circuit protection.
If the machine manufacturer has not created a protection system, we recommend
installing a fuse up-line from the coil rated at double the maximum current value the
coil is designed to withstand.
5 Maintenance
No type of routine maintenance is required for this device. We recommend replacing
the coil immediately on the occurrence of faults or breakages.
6 Removal, deactivation, and scrapping
The equipment is composed of a steel frame.
All components installed inside the frame are sourced on the market and they
contain materials typically used in the light industrial sector including: steel for the
metal cage, copper for the solenoid, aluminium, polyamide resin with fibreglass
fillers (PA66GF12 and PA66GF35).
For recycling or disposal of the materials, refer to the national laws and regional
regulations in force concerning the disposal of solid industrial waste and hazardous
substances.
