Important Safety Instructions
5815,5013US / Version 05 3
Important Safety Instructions
Read and follow all instructions.
Never let children operate or play with barrier controls.
Keep the remote control (where provided) away from
children.
Personnel should keep away from a barrier arm in motion
and keep the moving barrier arm in sight until it is
completely closed or opened. No one should cross the
path of a moving barrier arm.
Test the barrier system monthly. After adjusting the force
or the limit of travel, retest the barrier system. Failure to
adjust and retest the barrier system properly can increase
the risk of injury or death.
Keep barrier properly maintained. Read the owner's
manual. Have a qualified service person make repairs to
barrier hardware.
The barrier is for vehicles only. Pedestrians must use
separate entrance.
Save these instructions.

2 Safety
2.1 Intended use of the barriers
The MAGNETIC MHTMTM MicroDrive barrier is intended for
installation only on passageway used for vehicles. Pedestrians
must be supplied with a separate access opening. The pedestrian
access opening shall be designed to promote pedestrian usage.
Locate the barrier such that persons will not come in contact with
the vehicular passageway during the entire path of travel of the
vehicular barrier.
The barrier is either controlled by a person in manual operating
modes or by access control systems in automatic operating modes
and monitored by induction loops and/or safety light barriers.
Electrical energy is used exclusively for operating the barrier. The
barrier arm weight is balanced out by spring energy.
The barrier consists of the barrier housing with drive system and
control, as well as the barrier arm.
2.1.1 Intended use for certain road vehicles
Certain road vehicles according to chapter 2.1 paragraph 1 need to
have sufficiently large metal areas in the vehicle floor area to
enable detection by induction loops.
Other or complementary safety facilities must be provided for road
vehicles that cannot be detected by induction looks due to the
metal area in the vehicle floor area being too small.

Barrier MHTMTM MicroDrive Access and Parking
Safety
5815,5013US / Version 05 15
2.1.2 Non-Intended use
Control of pedestrian traffic as contrary to intended use.
The barriers must not be used at railway crossings.
The barriers are not approved for pedestrian traffic, bicycles or
animals.
The barriers must not be used in explosive environments.
All uses not described as intended use are prohibited.
No accessories must be connected or installed if they are not
specified expressly according to quantity and characteristics and
approved by Magnetic Autocontrol.
WARNING
Non-intended use is dangerous!
Every non-intended use can lead to dangerous
situations.
– Only use barrier as intended.
– All specifications in these operating instructions
have to be strictly complied with.
Any types of claims due to damage arising from improper use are
excluded. The operator alone shall be responsible for any damage
arising from improper use.

2.2 Operator's responsibility
The operator must comply with the statutory obligations regarding
work safety.
In addition to the work safety notes in these operating instructions,
the safety, accident prevention and environmental provisions
applicable for the area the barrier is used in must be complied with.
In particular, the operator must:
gather information on applicable work protection provisions.
determine additional dangers in a risk assessment.
implement the required method of operation of the barrier on
site from the operating instructions.
regularly verify throughout the barrier's time of use that the
operating instructions drawn up by him comply with the current
state of the regulations.
adapt the operating instructions to any new provisions,
standards and usage conditions - where required.
clearly determine the responsibilities for installation, operation,
maintenance and cleaning of the barrier.
ensure that all employees that are working at or with the barrier
have read and understood the operating instructions.
Furthermore, the operator must train personnel regarding the
use of the barrier at regular intervals and provide information on
possible dangers.
Furthermore, the operator is responsible for:
keeping the barrier in perfect technical order and condition at all
times.
maintaining the barrier according to the maintenance intervals
and performing the safety inspections as stipulated.
checking all protective facilities for completeness and proper
function at regular intervals.
The operator is also responsible that the danger area of the barrier
arm cannot be accessed by any unauthorised, and in particular not
by children, under any circumstances.
2.3 Changes and modifications
Changes, modifications and re-builds of the barrier or installation
can cause unforeseen danger.

2.4 Specialists and operating personnel
2.4.1 Requirements
WARNING
Risk of injury in case of inadequate
qualification!
Improper handling can lead to considerable bodily
injuries and property damage.
– Have any activities only carried out by the
individuals designated for that purpose.
The operating instructions specify the following qualification
requirements for the different fields of activity:
Instructed people
have been instructed during instructions provided by the
operator with regard to the work assigned to them and possible
hazards arising from improper conduct.
Specialised staff
are able, due their technical training, knowledge and experience
as well as their knowledge of the pertinent regulations able to
carry out the work assigned to it and to independently recognize
potential hazards.
Electrical specialists
are able, due to their technical training, knowledge and
experiences as well as knowledge of the relevant standards
and regulations, to execute tasks on electrical systems and to
independently recognize possible hazards.
In Germany, the electrical specialist must comply with the
provisions of accident prevention regulation BGV A3 (e.g.
master electrical fitter). Appropriate regulations apply in other
countries. The regulations valid there must be observed.
The installation is to be made by a professional installer
according to NFPA 70 National Electrical Code and Local Code.
MHTMTM MicroDrive service experts
comply with the requirements of the electricians named here.
Additionally, these electricians are trained and authorised by
MAGNETIC to perform special repair and service work on
MHTMTM MicroDrive barriers.
It must be expected that only those people are deployed who carry
out their work reliably. People, whose ability to respond is affected,
e.g. by drugs, alcohol or medicines, must not be used.
Furthermore, the age and profession-specific regulations valid at
the operating location must be observed when selecting personnel.

2.6.2 Hazard notes and occupational safety
For your own safety and for the protection of the barrier
modules, the following information must be observed and
complied with:
Electric voltage
DANGER
Mortal danger by electric voltage!
Touching live parts can be lethal.
Damage to the insulation or to individual
components can be lethal.
– Switch off the power supply immediately in case
of damage to the insulation and arrange repair.
– Only electrical specialists may carry out
work on the electrical system.
– Switch off power supply and secure against re-
activation before performing any work. Test for
absence of voltage!
– Never bypass or deactivate fuses.
– When replacing fuses observe the correct
amperage specification.
– Keep moisture and dust away from live parts.
Moisture or dust may cause a short circuit. If the
electrical connection is established during
precipitation, e.g. rain or snow, penetration of
moisture must be prevented by suitable
measures, such as a protective cover.

are permitted by the manufacturer may be
installed.
– Keep barrier area free from objects.
– Do not use the barrier arm as a lifting device.
– Never climb over or crawl under arm.
– Never sit on the barrier housing or climb over it.
– Do not sit or have yourself lifted by the arm.
– Never open or stop the arm manually.
