Minimum
enclosure volume
Siemens 3NA38 series fuses and 3RV series motor starter protectors of a lower current rating than shown may also be used. The
inverter must be mounted in a suitable enclosure (e.g. metal equipment cabinet) and if a motor starter protector is used, the enclosure
interior volume should not be less than that shown in the table above.
Branch circuit protection according to UL standards
Use in North America requires protection devices that meet UL standards as detailed in the following tables. The inverter must be
mounted in a UL approved enclosure not less than the minimum enclosure volume unless the branch circuit protection is a class AJT
fuse by Mersen (Ferraz Shawmut).
Overview of the approved protection devices according to UL standards:
Protection device
Fuses of any manufacturer with faster tripping characteristic than class RK5 and rated 600V AC, e.g.
class J, T, CC, G, or CF
SIEMENS circuit breaker
SIEMENS Type E combination motor controllers
UL category
JDDZ
DIVQ
NKJH
The inverter is suitable for use on a circuit capable of delivering the short circuit current shown in the tables below when protected by
the branch circuit protection indicated.
