WARNING
♦
When operating electrical devices, certain parts of these devices are always
live.
¾
The following terminals can carry dangerous voltages even if the inverter is
inoperative:
♦
the power supply L/L1, N/L2, L3 resp. U1/L1, V1/L2, W1/L3
♦
the motor terminals U, V, W resp. U2, V2, W2
♦
and depending on the frame size the terminals DC+/B+, DC-, B-, DC/R+
resp. DCPS, DCNS, DCPA, DCNA
♦
Emergency Off devices in compliance with EN 60204 IEC 204 (VDE 0113) must
remain functional in all operating modes of the control device. Resetting the
Emergency Off device must not result in uncontrolled or undefined re-starts.
♦
In those cases, where short circuits in the control device can result in
considerable material damage or even serious bodily harm (i.e. potentially
dangerous short circuits), external measures or devices must be taken or fitted
to ensure that operation is not dangerous even if a short circuit does occur (e.g.
independent limit switches, mechanical locks etc.).
♦
MICROMASTER inverters work with high voltages.
♦
Certain parameter settings can cause the inverter to start up again
automatically after the supply voltage has failed.
♦
The motor parameters must be configured exactly to ensure perfect motor
overload protection.
♦
The device provides an internal motor overload protection system in compliance
with UL508C, section 42. See P0610 and P0335, the pre-setting for i
2
t is ON.
Motor overload protection can also be secured via an external KTY84 or PTC.
♦
This equipment is suitable for use in a circuit capable of delivering not more
than 10,000 (Frame Size C) or 42,000 (Frame Sizes D to GX) symmetrical
amperes (rms), for a maximum voltage of 460 V when protected by an H, J or K
type fuse, a circuit breaker or self-protected combination motor controller (for
more details see Appendix F)
.
♦
This device must not be used as an „Emergency Off device“
(see EN 60204,
9.2.5.4)
