WARNING
¾ Work on the device/system by unqualified personnel or failure to comply with
warnings can result in severe personal injury or serious damage to material.
Only suitably qualified personnel trained in the setup, installation,
commissioning and operation of the product should carry out work on the
device/system.
¾ Only permanently-wired input power connections are allowed. This equipment
must be grounded (IEC 536 Class 1, NEC and other applicable standards).
¾ Only type B ELCBs should be used with FSA to FSF. Machines with a three-
phase power supply, fitted with EMC filters, must not be connected to a supply
via an ELCB (Earth Leakage Circuit-Breaker - see DIN VDE 0160, section 5.5.2
and EN50178 section 5.2.11.1).
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
¾ Always wait 5 minutes to allow the unit to discharge after switching off before
carrying out any installation work.
¾ This equipment must not be used as an ‘emergency stop mechanism’ (see EN
60204, 9.2.5.4)
¾ The minimum size of the earth-bonding conductor must be equal to or greater
than the cross-section of the power supply cables.
¾ If the front cover (Frame Sizes FX and GX) has been removed, the fan impeller
is exposed. There is danger of injury when the fan is running.
CAUTION
The connection of power, motor and control cables to the inverter must be carried
out as shown in Fig. 2-11 on page 44, to prevent inductive and capacitive
interference from affecting the correct functioning of the inverter.
