Branch circuit protection:
Suitable for use on a circuit capable of delivering not more than
100000 rms symmetrical amperes, 500 V max., when protected by the
specified fuses ( Tab. 2-1).
Voltage of the fuses must at least be suitable with the input voltage of the
drive.
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, 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 with derating.
Use 75 °C copper wire only, except for control circuits.
Control card protection:
External fuse for 24 Vdc supply voltage of control terminal X2. Rated 4 A DC
fuse UL248-14.
