Safety guidelines
The following guidelines on safety and hazards are intended to protect you, third parties and
the product. Itistherefore essential youfollowthem.
Operating environment
The product must not come directly into contact with moisture or water. The system (ma-
chine/system, in which the product is installed) is only suitable for dry premises indoors.
When moving the product from cold to warm conditions, allow the product to adjust to the
change in temperature for a few hours, to avoid possible damage from condensation.
Do not install the product near devices which generate powerful electromagnetic fields. This
could impair itsoperation.
Avoid environments exposed to direct solar radiation, extreme heat, cold, humidity or mois-
ture.
Power supply (only applies to products with multiphase motors, brushed DC/brushless DC or AC
servomotors and a suitable motor output stage/controller)
Connect the power supply for the output stage of the multiphase motor/output stage of the
iMD10/iMD20 servomotor, the intermediate circuit of the final stage of the iMD40 servomo-
tor(L, N and PE terminals) or the isel single axis/multi-axis controller (e.g. iMC-P/iMC-S8,
MC-1-series, iPU-series, etc.) only to a grounded mains socket with a mains voltage of 230V
AC/50…60 Hz (single phase of the AC grid).
It is preferable to use for the output stage of the multiphase motor or the output stage of the
iMD10/iMD20 servomotor the original power supply recommended by isel Germany AG
(primary switching-mode power supply: 230V AC, secondary: 48V DC). Using a different,
inappropriate power supply renders the warranty null and void. In addition, using an unsuit-
able power supply is associated with risks from electrical currents, such as electric shock,
fire or short circuit!
If you observe faults, operate the EMERGENCY STOP button on the (single axis) controller,
the CNC control panel/CNC control console, the switchgear cabinet/switchgear box or a
manual control device. Activating the EMERGENCY STOP button interrupts the power
supply to the motor output stage. If the power supply used is damaged, you must not use it.
Have a qualified technician check and if necessary repair the product.
The linear unit
For safety reasons, in-house rebuilding and/or changing of the linear unit is forbidden.
In operation, the linear unit must not be covered by supplies (electricity or compressed air),
objects (e.g. tools) or tarpaulins, packaging or other materials etc. (e.g. clothing), because
this can lead to mechanical damage or heat obstruction and sometimes fire.
If using a single-axis/multi-axis controller to control a linear unit (equipped with an AC,
brushed DC (BDC) or a brushless DC (BLDC) servo motor), you need to ensure that the
controller or motor output stage used (in a control cabinet or on a mounting rack) is placed
in a well-ventilated environment.
