OPERATING PRECAUTIONS
(1) Handling and installation
- The SG-ser
ies drive can be heavy. Lift according to the weight of the product.
Use a hoist or a crane to
m
ove and install the SG-series drive if necessary. Failure to do so may result in personal injury or dama
ge
to the drive.
- Do not
place heavy items on the drive. Do not stack the drive boxes higher than the num
ber
reco
mmended.
- Install the drive according to instructions specified in this m
anual.
- Check that the drive m
ounting
orientation is correct.
- Do not
drop the drive or subject it to hard im
pacts.
- Verify
that the ground impedance is 100 ohms or less for 230 V Class drives and 10 ohms
or less for 460V
class drives.
- Take protective measure
s against ESD (Electrostatic Discharge) be
fore touching the PC boards during
inspection, installation, or r
e
pair.
- The drive i
s designed for use under the following environm
ental conditions:
Environment
Ambient temp. - 10 ~ 40 C (14F ~ 104F)
Relative
humidity
90% Relative Humidity or less (non-condensing)
Storage temp. - 20 ~ 65 C (-4F ~ 149F)
Location
Protected from corrosive gas, combustible gas, oil mist or
dust. (Pollution Class 2 environment)
Altitude,
Vibration
Max. 3300 ft. (1000m) above sea level
Max. 5.9m/sec
2
(0.6G) or less
Atmospheric
pressure
10~15 PSI (70 ~ 106 kPa, 20.67 in Hg ~ 31.3 in Hg)
(2) Wiring
- Do not connect power factor correction capacitors, su
rge suppressors, or a RFI filter to the output of the
drive.
- The connection orientation of the m
otor output cables U, V, W will affect the direction of rota
tion of the
m
otor. Verify
correct wiring before starting drive.
- Incorrect ter
minal wiring could result in drive and/or equipment dama
ge.
- Reversing the polarit
y (+/-) of the Px and N terminals could damage the drive.
- Only author
ized personnel familiar with Benshaw drives should perform
wiring and inspections.
(3) Trial run
- Check all param
eters during operation. Parameter values might require adjustment depending on th
e
application.
- Alway
s apply voltage within the permissible range of each terminal as indicated in this manual. Otherwis
e,
drive damage may
result.
