INSTALLATION AND MAINTENANCE
VARMECA - 10
Variable speed motor or geared motor
CONNECTIONS
LEROY-SOMER
Réf. 3195 - 4.33/d - 12.99
3.2.4 - Control terminal block
This is located on the side printed circuit and used for remote
control.
To open blade terminals use a flat screwdriver (maximum
width 2.5 mm).
Standard configuration
On leaving the factory, terminals 5 and 6 are connected
together (ramp 5s) as are terminals 6 and 8 (forward).
Optional configuration
It is possible to control the motor using preset speeds, PI feedback,
etc, by setting the parameters using the console or
PEGASE VMA
10 option (see VARMECA - 10 manual - Parameter-Setting).
3.2.5 - Fault relay terminal block
3.2.6 - Connection (standard configuration)
• All connections and work must be carried out with
the power switched off.
When connecting a 10 k
Ω
potentiometer for remote control,
use the "without control button" option. However, if you have
the standard "with control button" version, it is essential to set
mini dip switch K4 to ON.
3.3 - Electrical and electromagnetic
phenomena
The VARMECA - 10 complies with the electromagnetic
compatibility directive 89/336/EEC, modified by 92/31/EEC,
provided it is fitted with the EMC filter option.

3.4 - Description of cables and protections
• When using a circuit-breaker, it must be a motor circuit-breaker (curve D).
• Comply with the size of protection fuses.
• The cable size may vary according to legislation applicable in the country, which will take precedence over the
values given in the table below without exception.
• These tables should never be used instead of current standards.
Note : The mains current value is a typical value which depends on the source impedance. The higher the impedance, the lower
the current.
