1.6 - Description of cables and protection devices
• It is the responsibility of the user to connect and provide protection for the VARMECA 30 in accordance with the
legislation and regulations in force in the country of use. This is particularly important as regards the size of cables,
the type and rating of fuses, the earth or ground connection, powering down, acknowledging faults, insulation and
protection against overcurrents.
• These tables are given for information only, and must under no circumstances be used in place of the current
standards.
• When using a circuit-breaker, it must be a motor circuit-breaker (D curve).
• The residual current device must be type B. Too many devices connected to a single residual current device can cause it
to trip. Check that the circuit-breaker is only protecting the VARMECA.
• Comply with the size of protection fuses.

Variable speed motor or geared motor

• All connection work must be performed in accordance
with the laws in force in the country where the drive
is installed. This includes earthing to ensure that no
directly accessible part of the drive can be at the
mains voltage or any other voltage which may be
dangerous.
• The voltages on the cables or connections of the mains
supply, the motor, the braking resistor or the lter may
cause fatal electric shocks. Contact must be avoided in all
circumstances.
• The drive must be supplied via a circuit-breaking device
so that it can be powered down safely.
• The drive contains capacitors which remain charged at a
fatal voltage even after the power supply has been cut off.
• Wait 2 minutes after powering down the drive before
removing the protection devices.
• The drive power supply must be protected against
overloads and short-circuits.
• It is vital to respect the rating of protection devices.
• Connection with copper conductor only.
• Check that the voltage and current of the drive, the motor
and the mains supply are compatible.
• After the drive has been operating, the heatsink or the
braking resistors may be very hot (avoid touching them).

• The VARMECA 30 has a positive logic conguration.
Using a drive with a control system which has a different
control logic may cause unwanted starting of the
motor.
• The control circuits in the drive are isolated from the
power circuits by single insulation (IEC 664-1). The
installer must ensure that the external control circuits are
isolated against any human contact.
• If the control circuits need to be connected to circuits
conforming to SELV safety requirements, additional
insulation must be inserted to maintain the SELV
classication.
2 - INSTALLATION
• It is the responsibility of the owner or user to
ensure that the installation, operation and
maintenance of the drive and its options comply with
legislation relating to the safety of people and equipment
and with the regulations in force in the country of use.
• Before carrying out any work, disconnect and lock the
drive power supply. For the single-phase range, wait 2
minutes to make sure that the capacitors have discharged.
• After connection, ensure that the seals are rmly in place,
and that the screws and cable glands are watertight to
ensure IP 65 protection. Tightening torque for cover
screws : 5 Nm.
• Holes are provided at the lowest points of the enclosure,
depending on the operating position, to drain off any
moisture that may have accumulated inside during
cooling of the machine. In conditions which encourage
the formation of condensation, it is advisable to leave the
drain holes permanently open.
• When the cover is open, the VARMECA 30 degree of
protection is IP10. Any work should only be carried out by
experienced, qualied personnel.

• Check that the terminal block has been removed from its xed holder (unplugged) before making any connections,
so as to avoid putting pressure on the card.

Note: For the VMA 31/32, PB1 and PB2 are both
located on the same terminal block.
The terminal block on the VARMECA 31/32 has a terminal
marked FI connected to the R- terminal which enables use
of the internal braking resistor. The jumper must be
removed when an external braking resistor is connected
or if the inertia is incompatible with the rated deceleration
ramp.

- The VARMECA can only be powered by the mains when it is mounted on the motor and the motor is earthed.
- If the VARMECA is powered when it is not mounted on the motor, the user must connect the mechanical earth (casing)
to earth.

• The safety input is a safety component which must
be incorporated into the complete system dedicated
to machine safety. As for any installation, the complete
machine must be the subject of a risk analysis by the
integrator which will determine the safety category with
which the installation must comply.
• The safety input, when open, locks the drive, meaning
the dynamic braking function is no longer available. If a
braking function is required before the drive safety lock is
applied, a time-delayed safety relay should be installed to
activate locking automatically after the end of braking.
If braking needs to be a machine safety function, it should
be provided by an electromechanical solution since the
dynamic braking by the drive function is not considered to
be a safety function.
• The safety input does not provide the electrical isolation
function. Before any work is carried out, the power supply
must be cut by an approved isolating device (isolator,
switch, etc).
• The safety function is not enabled when the drive is
controlled via the keypad or via a eldbus.
