Installation and Connection
• Always note the rated voltage, select the appropriate over current protection devices, select
a disconnect device, and select the proper wire size before beginning the wiring process.
Wire the COMBIVERT F5 according to NEC Class 1 requirements.
• Always use UL listed or CSA approved copper wire with a minimum temperature rating of
75°C. The wire gauge listed in the tables in section 2.3 is based on the maximum fuse rating,
copper wire and a 75°C insulation rating (THHW or equivalent). If a lower level of over current
protection is used, it may be possible to reduce the size of the wire. Use 300V rated wire for
230V systems and 600V rated wire for 460V systems.
• A disconnect switch or contactor shall be provided as a means of turning off the supply
voltage. Repetitive cycling on and off of the supply voltage more than once every 5 minutes
can lead to damage of the unit.
• B Housing and Larger: Class J (Bussmann type LPJ or equivalent) fuses or a circuit breaker
with type D trip characteristic must be used to provide branch circuit protection of the
COMBIVERT F5. The voltage rating of the fuse or circuit breaker shall be at least 250V for
230V units and 600V for 460V units. See tables in section 2.3 for over current protection
amperage ratings.
• A Housing: Class CC (Bussmann type LP-CC or equivalently) fuses or a circuit breaker with
type D trip characteristic must be used to provide branch circuit protection of the COMBIVERT
F5. The voltage rating of the fuse or circuit breaker shall be at least 250V for 230V units. See
table in section 2.3 for over current protection amperage ratings.
• B Housing and Larger: Terminal tightening torque for the power terminals is 0.5 Nm / 4 lbin
• A: Housing: Power connection must be installed as indicated on the previous page. Always
be sure to double check power connections for tightness.
• For installation requiring line side ground fault protection (GFI) consult KEB.
• Line chokes can be used to reduce harmonics, conducted high frequency noise, and can
extend the lifetime of the unit. Consult KEB for more information.
