CHAPTER 3 -
INSTALLATION AND WIRING
3.1 Installation precautions
1) Handle VFD with care to prevent damage to the plastic
components. Do not hold VFD by the front cover.
2)
Do not mount
VFD on the equipment with excessive vibration
above 5.9 m/sec
2
.
3) Install VFD in a location where temperature is within the
permissible range 14~104
°
F (-10~40
°
C).
4) Install it on a non-combustible surface because VFD generates
heat during normal operation.
5) Mount VFD vertically (top up) for proper heat dissipation. Provide sufficient clearance for an airflow
around VFD.
Increase minimum clearance by one inch for 50~75HP VFDs, by two inches for 100~150HP
VFDs, by three inches for 200~300HP VFDs, by four inches for 350~700HP VFDs to provide sufficient
cooling airflow.
6)
Do not mount
VFD in direct
sunlight or near other heat sources.
7) VFD shall be mounted in a
Pollution Degree 2 environment.
If VFD is going to be installed in
an environment with a high
probability of dust, metallic
particles, mists, corrosive gas or
other contaminants, the VFD must
be mounted inside the appropriate
electrical enclosure with proper
NEMA, UL or IP rating and
adequate cooling. If VFD is mounted inside enclosure, the maximum allowed ambient temperature would be
12
°
F less than VFD rating (104
°
F-12
°
F= 92
°
F). If VFD is de-rated by 20%, the maximum allowed ambient
temperature for it will be increased to 122
°
F and for the enclosed VFD to 110
°
F (122
°
F-12
°
F= 110
°
F). If
VFD is enclosed in ventilated enclosure and installed in direct sun light, the maximum ambient temperature
for white enclosure will be, as minimum, 25
°
F less than VFD rating (104
°
F-25
°
F= 79
°
F) and for 20% de-
rated VFD 97
°
F (122
°
F-25
°
F= 97
°
F). Thus, the VFD for direct sun light installation should be enclosed in
an air-conditioned enclosure.
8) Mount VFD using proper screws or bolts.
9) When two or more VFDs are installed in a ventilated enclosure, the cooling system should provide
adequate airflow for all the VFDs. Do not install VFD above another heat source (another VFD, inductive
reactors, etc.)
