Regular Servicing - Nidec Leroy-Somer LSPX Manual De Instrucciones

• Any reheating resistances (or reheating by injection of low voltage alternating current) must only be supplied
when the motor is powered down and cold; their use is recommended for an ambient temperature of < -20°C.
• When fitting one or more vibration sensors or accessories (pulse generator for example) these should
be connected in a box. All of these accessories (as well as the box if it is not placed outside an explosive
atmosphere) must be of a type certified by the group, the application (D) and the temperature class must
correspond at least to that of the motor. The instructions in their instruction manuals must be respected when
they are installed and current regulations.
• If the motor is supplied by a separate frequency inverter placed outside the zone or used where there is an
insufficient flow of air or which may be adapted to be no longer self-ventilating or fitted with an anti-drift device,
it must be fitted with thermal sensors in the winding (all frame sizes), on the DE bearing, and possibly on the
NDE bearing.
• 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).

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.
