6.6 Electric connections
It is absolutely necessary, before making any connections, to check the supply voltage with a tester.
The voltage that is measured must correspond with the voltage indicated on the unit label.
The installer must install, upstream from the unit, an isolating switch with fuse and capacity as speci-
fied on the label in order to permit maintenance on the machine with total absence of electricity.
The ON-OFF key on the C7000 is only used to switch off the control. It must not be considered to
be a safety component permitting maintenance on the unit. Maintenance must only be carried out
after having isolated the power supply to the unit (see previous note).
All electric connections and wiring must be done exclusively by authorized technical personnel.
The system must be equipped with an effective ground connection.
Optionally, CyberRow units can be provided with an additional terminal to connect emergency
power supply. Emergency line supplies the whole unit and it must have the same features as the
main supply line.
The electric connection to the climate-control system must comply with the following regulations:
Machine safety directive (2006/42/CE)
Low voltage directive (2006/95/CE)
Electromagnetic compatibility directive (2004/108/CE)
National mechanical and electric systems regulations
• Cut off every power supply line before working on the unit;
• Section of power supply cables must be selected in accordance to their length, kind of power supply and the current
absorbed by the unit, as prescribed by current regulations. These cables must comply with currently applicable
standards. In any case we recommend using shielded cables unless the installer carries out, at his expense,
tests that demonstrate that shielding is not necessary;
• Check that the power cables are installed at an adequate distance from alarm, communication and monitoring
cables;
• On the main power supply line, install an all-phase circuit breaker with type C curve. The size of the circuit breaker
must be determined according to the maximum current consumption of the components (st options). Do
the same on emergency power supply line, if existant.
• The ground fault switches on the whole power supply lines to the unit must be industrial type B, In = 0.3 A
• Connect main power supply cables from the distribution panel of the site to the unit power terminals located in-
side its electric box. The cables can be routed through the same openings used for pipes placed both on top and
bottom panels of the unit, as shown in the drawings in paragraph 6.2
• Repeat the same procedure to connect also emergency power supply, if available.
Only for CyberRow size 1: electric box of the unit can rotate on its side for a better accessibility
during maintenance. Lay out cables inside the unit so that they not impede its free movement.
