m ZRequirements to the connecting cables– on page 168
n Use 60 °C/75 °C copper wire only for all devices
n Use Class 1 wire only.
m ZElectrical connection power unit– on page 191
n Note tightening torque for connection terminals.
m Only for water-cooled devices:
n In order to avoid internal condensation: The temperature of cooling water supply
must be higher or at least equal to the internal temperature of the device.
n Maximum cooling water temperature 60°C
n Maximum water pressure 3 bar / 300 kPa in the cooling circuit.
m ZRequired environmental conditions– on page 55
n Use the device only in a pollution degree 2 environment
n Observe the maximum environmental temperature and the derating
m ZRequirements to the energy supply / supply system– on page 52
n Observe the short circuit current capability.
The device is rated for a maximum Short Circuit Current Rating (SCCR) of 65 kA,
480
V AC.
n 24 V supply must not reach more than 30 V DC. Additional fuse protection with max.
4
A fuse.
m ZFuses– from page 273
n Converters may be used with listed fuses or listed circuit breakers DIVQ as overcur-
rent protection.
m ZRequirements for the motor temperature sensors– from page 170
n Observe the connecting data of the motor temperature sensor.
cUL notes Additional only for Canada:
NOTE
Overvoltage Protection Device have to be installed in front of the input circuit of the
device to limit the maximum overvoltage peak to 2.5 kV.
