Warnings!
ƒ
Motor Overload Protection
–
For information on the protection level of the internal overload
protection for a motor load, see the corresponding manuals or
software helps.
–
If the integral solid state motor overload protection is not used,
external or remote overload protection must be provided.
ƒ
Branch Circuit Protection
–
The integral solid state protection does not provide branch circuit
protection.
–
Branch circuit protection has to be provided externally in accordance
with corresponding instructions, the National Electrical Code and any
additional codes.
ƒ
If mounted on a motor the environmental rating tests for Type 4 and
Type 12 shall be performed.
ƒ
Fuses/circuit breakers
–
See this manual for maximum fuse/circuit breaker sizes and circuit
breaker types.
–
Voltage rating of the fuses and circuit breakers must at least be
suitable for the input voltage.
