• In the applications with braking (lifting or handling) or when the network power supply voltage is greater than 415V,
Leroy-Somer recommends the use FLSD motors; alternatively Leroy-Somer proposes in (F)LS.N a 'reinforced
insulation' (over-insulation).
• When a drive is used, any special instructions detailed in the specific drive manual must be complied with.
• When several motors are supplied by the same drive, provide individual protection on each motor starter
(thermal relay) for safety reasons.
REGULAR SERVICING
• The frequency of inspections depends on the climactic and specific operating conditions and will be established
after one year of use.
• At least once every six months, drain any condensation water from the lower points of the casings by opening
and cleaning them and replacing the plugs with new seals.
• When closing the junction box, make sure that all the waterproof seals are positioned correctly and that CAF30
or CAF33 silicon sealant is applied on one of the 2 contact surfaces.
• Ensure that the screws are properly tightened in order to guarantee the IP protection level marked on the
nameplate.
• Remove dust from the machine frequently from casing and the cover openings and air outputs (risk of increased
surface temperatures): clean at low pressure from the centre to the edges of the machine.
• Instructions for IIC and III motors: electrostatic risk. See § IMPORTANT at the beginning of these instructions.
Unless prior agreement is received from the manufacturer, any intervention which may affect the safety of
the motor is performed under the responsibility of the operator. The repairs must be carried out by an
ATEX-approved repair specialist.
