Warning
· Use only PELV circuits as per IEC/DIN EN 60204−1 (ProĆ
tective Extra−Low Voltage, PELV) for the electrical supply.
Consider also the general requirements for PELV circuits
in accordance with IEC/DIN EN 60204−1.
· Use power supplies which guarantee reliable electrical
isolation of the operating voltage as per IEC/DIN EN
60204−1.
By the use of PELV circuits, protection against electric shock
(protection against direct and indirect contact) is guaranteed
in accordance with IEC/EN 60204−1 (Electrical equipment for
machines, General requirements).
Caution
Serious damage to the device !
· Make sure the polarity is correct.
· Do not disconnect any cables before the power supply
to the system is switched off.
For rated output in the designated application range a power
unit with 48 V DC is required. The SEC−ST can also be operĆ
ated with 24 V DC. Losses in the dynamics of the stepper moĆ
tors must be taken into account here (see data sheet for the
stepper motors).
