1.3. Exclusion of liability

1.4. Indication of copyright and protective right

This Mounting Instruction (MI) is part of the gear unit as supplied and must be read carefully before working with the gear
unit. The instructions in the MI must be followed. Keep the MI close to the gear unit.

We assume no liability for damages or disruptions of operations resulting from the failure to observe this MI.

In order to develop the product further, the producer reserves the right to make modications to the individual components

or assemblies that are believed to be useful to improve the product, while maintaining its essential characteristics.

Protection class:

The gears are in accordance with Protection Class IP 65.
Motors are designed within Protection Class IP 55 at minimum (see nameplate).

Intended use:

The gears / geared motors are exclusively assigned for the generation of a dened rotary motion within machinery and

plants. The gears comply with the basic requirements of the machinery directive 2006/42/EC as far as possible.
Any other use or utilisation above this is deemed a not intended use. The user / operator of the machine / plant is solely
liable for damages resulting therefrom.
The details in this mounting instruction, on the nameplate as well as in other technical documentation, are to be considered
and observed.

Intended use for motors:

The motors comply with the basic requirements of the Low Voltage Directive 2014/35/EU. They are designed for power
operating as well as operating in combination with frequency inverters.

Standard motors are designed for use at:

■ Ambient temperatures of -20°C (-4°F) to +40°C (104°F)

■ Altitudes of ≤ 1,000 m above sea level

You must comply with the information contained in this MI to ensure safe operation of the gear unit, geared motor and to

achieve the specied product characteristics and performance requirements.

The producer assumes no liability for injury to people or damage to equipment or property resulting from non-observance
of this MI. In such cases, any liability for defects is excluded.

All technical documents are protected in the sense of the copyright law. The processing, reproduction and dissemination of
it, even in extracts, as well as other utilisation is not allowed, unless it has been expressly conceded in written form.

WARNING!

All safety and warning instructions must be followed without exception!

Warning of electrical or mechanical danger

ATTENTION!

Important instructions for safe and trouble-free operation

2. General safety

The customer is responsible for setting up the drive in accordance with good engineering practices.

The instructions in this Mounting Instruction must be followed to achieve the conrmed characteristics of the drive units and

to ensure approval in case of warranty claims.

Make certain that you never put damaged products into operation!

Read this Mounting Instruction carefully before you begin any setup, installation or maintenance work.

Installation, start-up, maintenance and repair work on the gear unit / gear motor as well as on electrical accessory equip-

ment may only be performed by qualied technical personnel, taking the following items into account:

■ Operating Instructions

■ Information labels/tags on the gear unit / geared motor

■ All other project documents, setup manuals, operating manuals

■ Drive-specic specications and requirements belonging to the drive unit

■ The applicable regional and national regulations on safety and accident prevention

Work is only permitted:

■ on the stationary drive,

■ while disconnected and

■ prevented from being switched on again.

Operation of the drive unit by means of a frequency inverter may only occur if the specications shown on the motor name­plate have been carried out.

WARNING!

E-8 | WG20 Geared Motors

5. Storage

General:

The following items must be taken into account when storing the gear units:

■ In general, the drive units must be stored in closed rooms.

■ Ambient temperature max. 25 °C (77 °F)

■ Relative humidity max. 80 %

■ The drive units are to be protected from exposure to the sun or UV light.

■ No aggressive or corrosive materials are to be stored in the vicinity of the unit.

■ The gear units are to be stored in the same position that is intended for a later use.

■ The gear units are to be rotated 1-2 revolutions on the output side every 6 months to ensure that the interior parts are

wetted with lubricant.

■ The units are to be protected from mechanical loads and exposure to outside forces.

Long-term storage:

■ When the gear units are to be stored for longer than 12 months, they must be completely lled with lubricant as stated

on the nameplate or lubricant plate.

■ Unnished, bare-metal parts on the outside of the unit are to be protected with a corrosion protection product

(inspection every 6 months is recommended). The corrosion protection must be replaced after one year.

■ Before starting the gear unit, drain the lubricant from it. If more than one lubricant chamber is present, make certain that

all of the lubricant chambers have been drained out.

■ Gaskets settle, especially after a longer period without loading. Before starting, the screws must be retightened.

■ Then ll the gear unit with the lubricant type specied on the nameplate using the specied quantity.

■ If the gear units are stored for longer than 24 months before being put into service, they must be checked for leaks.

If there are any visible cracks on the surfaces of sealing elements, such parts must be replaced.
