Description of options
M23
Enclosure NEMA 1 filtered
Louvers and foam air filters are added to air inlet and outlet
openings (IP23). A NEMA 1 filtered enclosure is required to
meet the requirements for listing the enclosed drive
per UL508A.
M39
Mechanical door interlock (slam latch)
The circuit breaker operator is mechanically interlocked only
with the door of the cabinet containing the circuit breaker
(line connection module).
Option M39 provides mechanical interlocking of all other
doors, by means of a spring loaded pin protruding into a
bracket. This prevents any doors from being opened while
the drive disconnect is switched on
(unless the circuit breaker operator mechanism is defeated).

M43
Enclosure IP43
Similar to NEMA 1 filtered (M23), but additionally a 1 mm
wire mesh is provided behind the air filters.
M54
Enclosure NEMA 12 (ventilated)
Louvers and fine paper air filters are added to air inlet and
outlet openings (IP54), to prevent even fine dust particles
from entering the enclosure in very dusty environments.
These fine dust filters are a patented design for high volume
airflow with small derating. The drive current must be
derated to 95% with a NEMA 12 filtered enclosure.
M78
Motor side top cable exit
This option provides copper stabs and a ground connection
in the tophat above the power module, for connecting motor
cables entering the enclosure from above.
If option L61 or L62 is selected together with option M78,
the braking resistor should also be connected from above.
Note that the combination of standard options M78 with L08
(motor reactor) or L10 (dV/dt filter) is not possible. Please
consult factory if this combination is required.
P
20
: Permitted output for a period of 20 s, cycle time 90 s
If higher braking powers are required, please consult factory.
For drives with multiple power blocks, multiple braking
units and resistors may be connected. Refer to engineering
information for further information.
L87
Insulation Monitor for ungrounded supplies
An insulation monitor must be used if the drive is operat-
ed on an ungrounded power supply. This device monitors
the complete electrically connected circuit for insulation
(ground) faults. Two threshold values of resistance to ground
(between 1 k
c
and 10 M
c
) can be set (for alarm and fault).
Since the response philosophy to a ground fault may differ,
output relay contacts are not wired in the drive but available
for wiring to drive terminals or integration into a plant control
system. Additional terminals on the device are provided for
an output to an external display, and inputs for external reset
and test buttons.
Note: Only one insulation monitor can be used in an
electrically connected network.
L96
Input surge protective device
Type 1 Surge Protective Device per UL 1449 Third Edition,
wired to load side of incoming circuit breaker.
M06
Base (plinth) 4” (100mm) high
The 4” enclosure base allows
larger bending radii for cables
(cable entry from below) and
routing them within the base. It
is delivered already mounted to
the enclosure. The height of the
operator panel changes accordingly.
The base is always colored RAL 7022
(umbra grey). A special color is
not possible.
Enclosure with option M06
M07
Base (plinth) 8” (200mm) high
The 8” enclosure base provides more space for bending and
routing cables. The base is delivered already mounted to
the enclosure. The height of the operator panel changes
accordingly.
The base color is the same as the enclosure, RAL 7035 (light
grey). If the enclosure is ordered in a special color (option
Y09), the 8” base is also painted the same color.
