1 GENERAL SAFETY WARNINGS
AND PRECAUTIONS
Recommendations regarding safety
• ATTENTION! – This manual contains important instructions and recom-
mendations regarding the safety of persons. Incorrect installation can
cause serious injury. Read the manual completely before starting work. If in
doubt, suspend the installation and request clarifications from the Nice After-
sales Assistance.
• ATTENTION! – Important instructions: keep this manual for any future
maintenance interventions and product disposal.
• ATTENTION! – In compliance with the most recent European Legisla-
tion, the realisation of an automatic door or gate must respect the Stan-
dards envisioned by the 2006/42/CE Directive (ex 98/37/CE) (Machinery
Directive) and in particular, the EN 12445; EN 12453; EN 12635 and EN
13241-1 Standards, which allow to declare conformity of the automa-
tion. Considering this, all product installation, connection, inspection
and maintenance operations must only be performed by a qualified and
skilled technician!
Recommendations for installation
• Before starting installation, check whether this product is suitable to auto-
mate your gate or door (see chapter 3 and the "Product technical features").
If it is not suitable, DO NOT proceed with installation.
• All installation and maintenance operations must take place with the
automation disconnected from the electric power input. If the power
input disconnection device is not visible from the place where the automation
is positioned, before starting work, affix a sign onto the disconnection device
that states "ATTENTION! MAINTENANCE IN PROGRESS".
• Handle the automation with care during installation, preventing crushing, blows,
falls or contact with liquids of any nature. Do not place the product near to heat
sources or expose it to naked flames. All of these actions can damage it and be
cause of malfunctioning or dangerous situations. If this occurs, suspend installa-
tion immediately and contact the Nice After-sales Assistance.
• Do not modify any product parts. Unauthorised operations can only cause
malfunctioning. The manufacturer declines liability for damage deriving from
arbitrary modifications to the product.
• If the gate or door to be automated has a pedestrian door the plant must be
set up with a control system that prevents functioning of the motor when the
pedestrian door is open.
• The product packaging material must be disposed of in compliance with
local legislation.
2 DESCRIPTION OF THE PRODUCT
AND DESTINATION OF USE
This product is destined to be used to automate gates or doors with hinged
panels.
ATTENTION! – Any use different to that described and in environmental
conditions different to those stated in this manual must be considered
improper and prohibited!
The product is an electro-mechanical gear motor, with a 24 Vdc motor. The gear
motor is powered by the external control unit, to which it must be connected.
If the electric energy is interrupted (black-out), the gate panels can be moved
by releasing the gear motor using the relevant wrench; to perform the manual
manoeuvre, see chapter 8.
The product is available in the version
- BM5024 with encoder, suitable for MC824H control units.
Do not use gear motors with incompatible control units.

INSTALLATION
3.1 - Preliminary checks on installation
Before performing installation, check the integrity of the product components,
the adequacy of the model chosen and the suitability of the environment des-
tined for installation.
IMPORTANT – The gear motor cannot automate a manual gate that
does not have an efficient and safe mechanical structure. Moreover, it
cannot solve defects caused by incorrect installation or bad mainte-
nance of the gate itself.
3.2 - Suitability of the gate to automate and the surrounding
environment
• Check that the gate mechanical structure is suitable to be automated and
complies with the Standards in force on the territory (if necessary, refer to the
data given on the gate label).
• Moving the gate panel manually in Opening and in Closure, check that the
movement takes place with the same and constant friction in all points of the
run (there must not be moments of greater effort).
• Check that the gate panel stays in equilibrium, i.e. that is does not move if
taken manually into any position and left.
• Check that the space around the gear motor allows to manually release the
gate panels easily and safely.
• Envision end run retainers on the ground both for opening and closure of
the gate.
• Check that the gear motor fixing area is compatible with the clearance of the
latter (fig. 1).

3.3 - Limits of use for the product
Before installing the product, check that the gate panel has dimensions and
weight that lie within the limits given in graph 1; also evaluate the climatic con-
ditions (e.g. strong wind) present in the place of installation. They can greatly
reduce the values given in the graph.

3.4 - Set-up for installation
Fig. 2 shows an example of automated plant realised with Nice components.
These components are positioned according to the typical and usual layout.
With reference to fig. 2, establish the approximate position where each com-
ponent envisioned in the plant will be installed and the most appropriate con-
nection layout.
