Safety Instructions
NOTICE
♦ Keep these operating instructions within easy reach of the equipment and
make them available to all users
♦ Whenever measuring or testing has to be performed on live equipment, the
regulations of Safety Code BGV A2 must be observed, in particular §8
"Permissible Deviations when Working on Live Parts". Suitable electronic
tools should be used.
♦ Before installing and commissioning, please read these safety instructions
and warnings carefully and all the warning labels attached to the equipment.
Make sure that the warning labels are kept in a legible condition and replace
missing or damaged labels.
Transport & Storage
WARNING
♦ Correct transport, storage, erection and mounting, as well as careful
operation and maintenance are essential for proper and safe operation of the
equipment.
CAUTION
♦ Protect the inverter against physical shocks and vibration during transport and
storage. Also be sure to protect it against water (rainfall) and excessive
temperatures (see tableTable 7-1 on page 106).
Commissioning
WARNING
♦ 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.
♦ Only permanently-wired input power connections are allowed. This equipment
must be grounded (IEC 536 Class 1, NEC and other applicable standards).
♦ 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).
♦ The following terminals can carry dangerous voltages even if the inverter is
inoperative:
- the power supply terminals L/L1, N/L2, L3 resp. U1/L1, V1/L2, W1/L3
- the motor terminals U, V, W resp. U2/T1, V2/T2, W2/T3
- and depending on the Frame Size, the terminals DC+/B+, DC-, B-, DC/R+
resp. C/L+, D/L-
♦ This equipment must not be used as an 'emergency stop mechanism' (see
EN 60204, 9.2.5.4)
CAUTION
The connection of power, motor and control cables to the inverter must be carried
out as shown in Figure 2-13 on page 40, to prevent inductive and capacitive
interference from affecting the correct functioning of the inverter.
