INSTALLATION AND MAINTENANCE
VARMECA 14
(5.5 - 7.5 kW)
Variable speed motor or geared motor
MAINTENANCE
LEROY-SOMER
Ref. 3415 - 4.33/c - 01.02
6 - MAINTENANCE
• All work relating to installation, commissioning
and maintenance must be carried out by
experienced and qualified personnel.
• Before carrying out any work, disconnect and
lock the VARMECA 14 power supply circuit and wait 2
minutes for the capacitors to discharge.
6.1 - Care
No special care is required on the VARMECA 14, apart
from the regular removal of dust from the fan grille and the
cooling fins located at the bottom of the box.
Do not dismantle the VARMECA 14 while it is still under
guarantee, as this would then immediately become null
and void.
CAUTION:
Certain components which are sensitive to electrostatic
discharge may be destroyed simply by touching them.
Do not leave any metal object in the connection area, as
this could cause a short-circuit.
6.2 - Measurements
6.2.1 - General
The input voltages can be measured using ordinary
instruments.
The motor current is not measured on the VARMECA 14
power supply (L1, L2, L3). It is measured using an ordinary
clamp ammeter on the longest wire, which forms a loop on the
side of the connection circuit.
6.2.2 - Procedure for measuring the motor current
(if the motor wire loop is inaccessible)
- Open the VARMECA 14 power supply circuit and lock it.
- Wait 2 minutes for the capacitors to discharge.
- Open the cover of the VARMECA 14.
- Remove the mains cable (L1, L2, L3).
- Pass the longest motor wire along the side of the connection
circuit.
- Reconnect the mains (L1, L2, L3).
- Pass the clamp ammeter through the motor wire loop.
