Installation
WARNING!
ELECTRIC SHOCK HAZARD
Disconnect the mains supply
before working on the unit. DO
NOT TOUCH PRESETS, SWITCHES
AND JUMPERS! Always use the
correct insulated adjustment
tools.
2.1 Motor installation
• Foot-mounted motors must be level and
secure.
• Ensure accurate alignment of the motor
shaft and couplings.
• Do not hammer pulleys or couplings
onto the motor shaft.
• Protect the motor from ingress of
foreign matter during installation.
Earthing:
Connect the motor to the system
enclosure earth.
2.2 Drive Installation
Requirements during installation and
operation:
•
Optimise the heatsink airflow.
• Avoid vibration.
• Protect the drive from pollutants.
• Ambient operating temperature must be
within -10ºC and +40ºC. To comply with
UL requirements, the temperature of the
surrounding air must not exceed 50ºC.
POWER CABLING
: Use correctly rated
cable: minimum 600 Vac, 2 x armature
current
CONTROL SIGNALS
: The 1600i and 3200i
have isolated control terminals and as such
may be connected to other systems. Avoid
running signal cables close to power cables.
SUPPLY
: Please ensure that the supply
selection jumper on the drive matches the
incoming supply. Failure to do this may
result in permanent damage to the drive
unit and will invalidate any warranty.
FUSING
: The drive MUST BE FUSED
EXTERNALLY with semiconductor fuses that
MUST be rated at 1.75 x armature current,
and have an A
2
s rating lower than the I
2
t
Any warranty
will be invalid if this fusing is incorrect.

SUPPRESSION
: The drives have excellent
noise immunity. However, installations
involving electrical welding or RF induction
heating may require further filters on the
line and armature terminals. Contactor coils
and sparking contacts may also require
suppression. A 100 Ω resistor in series with
a 0.1 µF capacitor is usually adequate in
these situations. Refer to page 5 for
EMC guidelines.
CAUTION!
EQUIPMENT DAMAGE HAZARD
Reversing systems: do not
transpose the armature
connections until the motor has
stopped, otherwise damage will
occur.
CAUTION!
EQUIPMENT DAMAGE HAZARD
For frequent stopping or jogging,
it is not good practice to rely on
switching the supply off and on
to stop and start with the run
contact permanently closed.
This may result in an
uncontrolled current pulse for
one half mains cycle under
certain conditions, e.g. main
contact bounce. This could lead
to undesired motor movement
or device damage.
In rapid start-stop systems, use
a spare normally-open contact
on the main supply contactor
in series with T7 and any other
RUN contacts.
