Introduction
MATRIX CUBE - iv -
Prescription for a Safe Use of the System
The parts of MATRIX CUBE system which may cause an exposure to the hazards listed on Harmonized
Standard EN ISO 14121-1:2007 Machinery Safety – Principle of Risk Assessment are the following:
- The electrical box on board of the creel, due to the presence of harmful voltages (380/480 VAC three-
phase)
- The DIAPER FEEDER devices due to the rotation of elastic yarn feeding motor
- The creel stability according to configuration (
creel stacking possibility, frame mounted on wheel, etc. )
The protective measures to be adopted by the users are then the following:
ƒ The access to the inside of electrical box shall be allowed exclusively to skilled and
authorized maintenance staff.
ƒ During the system operation, the Plexiglas sliding protections of DIAPER FEEDER devices,
must be kept closed.
ƒ After any electrical maintenance work, make sure that the electrical box and the creel frame
are correctly connected to the protection earth system (PE clamp and stranded wires to
connect the various creel elements) .
ƒ Whenever a creel cleaning or maintenance operation is to be carried out at a height
exceeding 2 meters, use exclusively a footboard, a self-stable ladder or a suitable lifting
device.
Never lean a ladder to the creel and never try to use the creel frame to reach the top side of
the creel itself.
→ Falling risk due to the movable creel, that leans on wheels
ƒ Prior to open the electrical box, always turn off the main switch or disconnect the power
cord
ƒ In case of creels composed of 5 or 6 stacked modules, the wheels must be replaced by
fixed supports anchored to ground or ( as an alternative ) 8 angle brackets must be fastened
to the 4 edges of the bedframe and to the ground ( see example on picture A below ).
Moreover, make sure that all the creel modules are tightly interconnected by means of the
stranded wires shown on the picture of Paragraph 1.3 “System power supply”.
The stranded wires must be applied at least on 2 opposed creel side, as shown on picture
B below
