Branch circuit protection:
– Suitable for use on a circuit capable of delivering not more than 5000 rms
symmetrical amperes, 500 V max.
– Suitable for use on a circuit capable of delivering not more than 50000 rms
symmetrical amperes, 500 V max., when protected by CC, J, T or R Class
fuses.
– Use specified fuses as shown in the table. Voltage of the fuses must at
least be suitable with the input voltage of the drive.
– Above Short Circuit ratings are only valid when the Assembly Bases are
used.
– Above Short Circuit ratings are also valid when supplied by prescribed and
UL Listed, Lenze AC/DC Supply/Brake Units.
Transient surge suppression shall be installed on the line side of this
equipment and shall have met the requirements of CSA C22.2 No. 8, and
shall be rated 277 V (phase to ground), 480 V (phase to phase), suitable for
overvoltage category III, and shall provide protection for a rated impulse
withstand voltage peak of L−L 1.8 kV
The integral solid state protection does not provide branch circuit protection
and that branch circuit protection has to be provided externally in
accordance with manufacturers instructions, the National Electrical Code
and any additional codes.
For information on the protection level of the internal overload protection
for a motor load in percent of FLA, see the corresponding Application
Manuals or Software Helps.
For information on rating and proper connection of the thermal protector
(only for connection to motors having integral thermal protection), see the
corresponding Application Manuals or Software Helps.
Maximum surrounding air temperature: 55 °C.
Use 60/75 °C copper wire only, except for control circuits.
These products are intended for use in a pollution degree 2 environment.
