General safety and application notes for Lenze low−voltage machines
(according to Low−Voltage Directive 73/23/EWG)
1. General
Low−voltage machines feature dangerous live and rotating parts as well as possible hot surfaces. All work related
to transport, connection, commissioning and maintenance must be performed by qualified authorised technical
personnel (EN 50110−1 (VDE 0105−100); observe IEC 60364). Improper behaviour can lead to serious personal
injuries and property damages.
In case of synchronous machines, voltages are also induced at the open terminals if the machine turns.
2. Application as directed
These low−voltage machines are intended for commercial plants. They meet the harmonised standards of the series
EN 60034 (VDE O53O). The use in a potentially explosive atmosphere is prohibited, unless explicitly intended for such
a purpose (observe additional notes).
Do not use enclosures £ IP23 without special protective measures in the open. Air−cooled designs are rated for
ambient temperatures from −15 °C or −10 °C to +40 °C and site altitudes £ 1000 m amsl, from −20 °C to +40 °C
without brake or with spring−operated brake, nonventilated or with integral fan, from −15 °C to +40 °C with
permanent−magnet brake and from −10 °C to +40 °C with separate fan. Deviating information on the nameplate must
be observed. The conditions at the application site must correspond to all data on the nameplate.
Low−voltage machines are components for installation in machines according to the Machinery Directive 98/37/EG.
The commissioning is prohibited until the conformity of the end product with this directive is established (observe
EN 60204−1, among others).
The built−in brakes are not fail−safe brakes. It cannot be ruled out that a torque reduction occurs through interference
factors that cannot be influenced, e.g. oil entry through failure of the shaft sealing ring on the drive end.
3. Transport, storage
Immediately report damages detected after delivery to the forwarder; commissioning may have to be ruled out.
Securely tighten screwed−in transport eyelets. They are dimensioned for the weight of the low−voltage machine; do
not attach any additional loads. If necessary, use appropriate means of transport (e.g. rope guides).
Remove existing transport locking devices before commissioning. Reuse them for additional transports. If

low−voltage machines are stored, ensure that the environment is dry, dustfree and non−vibrating (v

(storage standstill damages). Measure the insulation resistance before commissioning. With values £ 1 kW per volt
of rated voltage, dry the winding.
4. Installation
Ensure even seating, good foot or flange mounting and exact alignment for direct coupling. Avoid installation−based
resonances with rotary and double supply frequency. Turn rotor by hand, look for unusual grinding noises. Check the
direction of rotation in the uncoupled state (observe section 5).
Fit or pull off belt pulleys and couplings using only appropriate devices (heating!) and cover with a protection against
accidental contact. Avoid impermissible belt tensions (techn. list).
The machines are balanced with a half featherkey. The coupling must also be balanced with a half featherkey.
Machine off any protruding visible featherkey portion.
Create any required pipe connections. Fit designs with shaft end pointing down with a cover that prevents foreign
bodies from falling into the fan. Ventilation must not be obstructed and exhaust air−−including adjacent units−−must
not be drawn in directly.
