Federal Communications Commission (FCC) Statement

This equipment has been tested and found to comply

with the limits for a Class B digital device, pursuant to part

15 of the FCC rules. These limits are designed to provide

reasonable protection against harmful interference in a

residential installation. This equipment generates, uses

and can radiate radio frequency energy and, if not installed

and used in accordance with the instructions, may cause

harmful interference to radio communications. However,

there is no guarantee that interference will not occur in

a particular installation. If this equipment does cause

harmful interference to radio or television reception,

which can be determined by turning the equipment

oﬀ and on, the user is encouraged to try to correct the

interference by one or more of the following measures:

· Reorient or relocate the receiving antenna.

· Increase the separation between the

equipment and receiver.

· Connect the equipment into an outlet on a circuit

diﬀerent from that to which the receiver is connected.

· Consult the dealer or an experienced

radio/TV technician for help.

This device complies with Part 15 of the FCC Rules.

Operation is subject to the following two conditions:

(1) this device may not cause harmful interference and

(2) this device must accept any interference received,

including interference that may cause undesired operation.

You are cautioned that changes or modiﬁcations not

expressly approved by the party responsible for compliance

could void the user’s authority to operate the equipment.

The CE label shows that the product complies with the

basic requirements of the applicable directives. For the

declaration of conformity contact the manufacturer at

servicing@intelligent-energy.com

· Only qualiﬁed technicians trained in high pressure ﬂammable gases

must carry out ﬁtting of regulators and ﬁlling of cylinders, and do so in

accordance with local laws and Health and Safety (H&S) regulations.

· The customer is responsible for ensuring all technicians and pilots are

suitably trained, accredited and in compliance with local laws and H&S

regulations.

· The customer is responsible for ensuring the safe operation of the

Lightweight Hydrogen Regulator.

· Do not open or dismantle the Lightweight Hydrogen Regulator.

· Do not remove any external covers or cowlings.

· Pressurised hydrogen present. Highly ﬂammable!

· Do not use the Lightweight Hydrogen Regulator if the unit is damaged.

· The Lightweight Hydrogen Regulator should be inspected for damage

and leak checked prior to use.

· Not to be used in residential areas (EMC).

When shipping or transporting your Unmanned Aerial Vehicle and

Fuel Cell Power Module (FCPM), the FCPM must always be disconnected

from the hydrogen source.

When transporting pressurised gas check for relevant local regulations.

Product Overview

The Lightweight Hydrogen Regulator has been designed for use with the

Intelligent Energy UAV FCPMs. It is intended to provide control and safety

features on a lightweight cylinder to allow use on UAVs. It is controlled from an

Intelligent Energy UAV FCPM. The Regulator has been designed to meet relevant

safety standards. It is designed to operate with compressed gaseous hydrogen.

Prior to operation the cylinder will need to be purged to remove

air impurities.

Once the regulator is ﬂush, apply a maximum torque of 58Nm (42.8ft.lb).

Always conduct a leak check on the completed assembly.

Assembly and connection3

Assembly of regulator to cylinder3.1

By hand, carefully thread the

regulator assembly into the cylinder.

Tighten the regulator until it is mated

ﬂush to the neck of the cylinder.

· Take the cylinder and regulator and inspect for physical damage or debris,

reject if visible to the eye.

· Inspect the mating threads for damage or debris, reject if visible to the eye.

3.3

Filling of cylinder

Only qualiﬁed technicians trained in high pressure and ﬂammable gases can carry

out ﬁtting of regulators and ﬁlling of cylinders, and do so in accordance with local

laws and Health and Safety (H&S) regulations.

A leak check must be conducted after ﬁlling the cylinder.

Consult local H&S / facilities management for guidance on storage of cylinders and

advisable safety equipment.

Hydrogen fuel

When installing and operating hydrogen systems, hydrogen general safety guidance

should be considered, for more detailed information see:

ISO/TR 15916 – Basic considerations for the safety of hydrogen systems

Hydrogen purity is an important consideration for fuel cell performance, it should

comply with the speciﬁcation in the table below for best performance:

For more details about hydrogen quality see the user manual for your FCPM

or contact Intelligent Energy Product Support, see Section 6

Fuel Characteristics Fuel Requirements

Hydrogen concentration > 99.90 %

Nitrogen, Helium, Argon < 0.10%

Oxygen < 50 ppm

Carbon Dioxide < 2 ppm

Carbon Monoxide < 0.2 ppm

Ammonia < 0.1 ppm

Sulphur containing compounds < 4 ppb

Max particle concentration < 1 mg/kg

Max particle diameter < 75 µm

8Assembly and connection3

3.4 Hydrogen connection

The Lightweight Hydrogen Regulator is designed to be connected to an

Intelligent Energy FCPM, please refer to the FCPM user manual for details of how

to make the hydrogen connection to that unit.

Ensure the hydrogen cylinder and FCPM are securely mounted

before proceeding.

Verify that the connector O-rings are in place and free from damage or debris.

Align the hose connector path with the regulator pins.

Push the hose connector and twist anti-clockwise. It will click when located.

Refuelling4

Symptom Reason(s) Action

High H2pressure fault Gas pressure

Contact Intelligent Energy Product Support

Low H2pressure fault No hydrogen supplied

from cylinder

Cylinder is empty

Gas pressure

regulation fault

1. Check cylinder pressure, reﬁll if needed

2. Inspect the solenoid valve cable

Replace if damaged

If the steps above do not resolve the issue,

contact Intelligent Energy Product Support,

see Section 6

Loss of cylinder pressure Leak between cylinder

and regulator

Leak from the regulator

1. Place cylinder and regulator in a well-

ventilated space, preferably outdoors

2. Purge the gas from the cylinder by lifting

the cap of the PRV, see diagram in section 2.2

3. When the cylinder is empty. A person trained

in the use of pressurised gas should remove

the regulator from the cylinder and inspect

the sealing o-ring. Replace if damaged

4. Reassemble and reﬁll the cylinder

5. Check for leaks

If the steps above do not resolve the issue,

contact Intelligent Energy Product Support,

see Section 6

Troubleshooting5

There are multiple ways to ﬁll cylinders and Intelligent Energy has application notes

available for some ﬁll options. Contact Intelligent Energy Product Support for details,

see Section 6.
