CAUTION
– Possible damage!
- Please note the wiring data on the specification and the permitted
mechanical loads (see technical data in the data sheet).
- Switch off the supply voltage before mounting and wiring the step-
per motor.
- Stepper motors must not be operated with mains voltage. Stepper
motors require special control units
- While press-fitting couplings or pinions on the motor shaft, the lat-
ter should be supported.
- Remove the PTFE tube only from the lead which you are just con-
necting (chapter 6.2.2).
- Never lift the motor by means of its cables or leads! Care for strain
relief when stripping or shortening the leads!
- Comply with EMC conform wiring (chapter 6.2.2).
- Do not open the stepper motor! If the casing is opened, the motor
may be damaged. Phytron's warranty does not apply if motors are
opened by the customer.
When operating a motor that was as-
sembled improperly, danger to life could be caused by electric
shock
.
- The customer must not carry out mechanical or electrical modifica-
tions of the motor. The warranty does not apply if the motor is mod-
ified by the customer without the manufacturer's permission
1.4 European Standards and CE Mark
When installed appropriately, space stepper motors fulfil the requirements of the EMC and
Low Voltage Directives. Space stepper motors are qualified to be marked CE and comply
with EN 60034-1 European Standard.
When wired correctly (see Fig. 5), space stepper motors fulfil the requirements of the EMC
Directive. Information concerning the connection of the motor cable to the control unit or
the power stage is given in the corresponding manuals.
According to the European Machine Directive, the stepper motor is only a part of a ma-
chine. Placing into operation is not allowed until the machine manufacturer takes appropri-
ate measures to ensure that the entire system fulfils the requirements of the applicable EU
Directives.
