Safety instructions
Application as directed
1 Safety instructions
ƒ These Operating Instructions are valid only in conjunction with the general
Operating Instructions for MDXM three-phase AC motors! It represents an
addendum and is amended with aspects concerning explosion protection. In
addition, please observe the safety instructions for gearboxes in the ATEX gearboxes
Operating Instructions.
ƒ If the data are inconsistent, these Operating Instructions have priority.
ƒ Pay attention to an installation according to EMC, especially for frequency inverter
operation!
If these Operating Instructions are disregarded, especially the inspection and
maintenance intervals, the EC declaration of conformity will become void.
1.1 Application as directed
The motors described in these operating instru ctions are designed specifically for direct
mounting on Lenze gearboxes of the G-motion series. In this design, the interface
between motor and gearbox can no longer be separated since components of the motor
become components of the g earbox and vice versa. Among other things, these
components also handle functions that ensure safe operation with respect to explosion
protection. For example, the shaft sealing ring of the motor handles the sealing of the
gearbox.For this reason, the subsequent text also refers to the geared motor since the
safety aspects listed here do not apply only to the motor and a separate operation of the
(without gearbox) would not make any sense.
The geared motors are intended for use in machinery and systems and may only be
used in accordance with these operating instructions, the nameplate and the text of the
order confirmation. They correspond to existing standards and regulations and meet
the requirements of EU directive 94/9/EG.
Explosive gas, fog, vapour, or dust atmospheres can cause severe injuries or death when
getting in contact with hot and / or sparking parts of the geared motor.
All operations concerning mounting, connection, commissioning as well as
maintenance and repairs on the geared motor and the electrical supplementary
equipment must only be carried out by qualified personnel!
ƒ During installation, EN 50281-1-2 in potentially explosive (dust) atmospheres must
be observed!

The machines can be used as follows:
A In zone 22 (dust Ex, category 3D) with non-conductive dusts with a minimum
ignition power > 3mJ.
