2.4 Inverter Watt Loss
The operation of the inverter generates heat
due to inefficiencies within the system. This
heat must be accounted for when mounting
the inverter within another enclosure. The
following table shows the watts generated by
the inverter when at full current and at
various switching frequencies. For specific
switching frequencies, use worst case
scenarios or consult the factory.
2.5 Line Fuse or Circuit Breaker Sizing
The user must provide either a circuit
breaker or a fused disconnect switch in
accordance with the National Electric
Code or Canadian Electrical Code and all
local codes. The following rules should
be used to select the correct size of the
input line fuses or circuit breaker.
A. Sizing/Fuse Type
The WFC HT Inverter is able to withstand
a 150% overload for 60 seconds.
For maximum protection of the inverter,
use the fuses listed in Table 2.5.
Recommended suppliers are Bussman
for 230 VAC, and for 460 VAC installa-
tions. Equivalent values from other man-
ufacturers may be substituted.
2.6 Wiring Practices
A. Applicable Codes
Care should be taken to insure that
field wiring is installed in accor-
dance with the National Electric
Code (NEC) or Canadian Electrical
Code (CEC) as a minimum stan-
dard. Where local codes exceed
these requirements, they must be
followed.
All WFC HT models are Underwriters
Laboratories Inc. (UL ® ) and
Canadian Underwriters Labora-
tories (cUL
® ) listed, and therefore
comply with the requirements of
NEC or CEC. Installations intended
to meet UL
® requirements must
follow the instructions provided
herein. Refer to the WFC
HT tech-
nical data plate and the motor
nameplate for electrical data.
