Before installation, read this notice carefully and keep it at
disposal of people in charge of installation, maintenance
and operation.

Safety
WARNING! Wait 5 min. after isolating supply before
handling. As an additional precaution before commencing
work, short-circuit the capacitor terminals with a piece of
insulated cable to confirm discharge.
For a safe use of CLMD capacitor units, please ensure:
1. Installation and maintenance are undertaken only by
authorized and qualified personnel, in accordance with
current local regulations;
2. Isolate the equipment from the supply before
attempting to gain access.
Inspection on reception
Unpack the CLMD and check that:
- data on the label correspond to those of your purchase
order and local regulations;
- the CLMD is not damaged.
Any loss or damage should be notified immediately to
your closest ABB agent.
Storage
Indoor, in dry, dust free and non-corrosive environments,
protected from vibrations or shocks.
Storage temperature: minimum: -40°C/-40°F, maximum:
75°C/167°F.
Transportation and handling (Fig. #1)
In case severe conditions of transportation are expected,
we recommend that the panel including CLMD units be
positioned in such a way that CLMD fixation points are at
the bottom. For CLMD33/33S, more positions are
allowed.
WARNING! Failure to respect installation rules may lead
to premature failure, other material damage to
installations or bodily injury.
INSTALLATION
Applicable standards
IEC 60831 Parts 1 and 2. Current local regulations.
Protection
CLMD13, 43, 53, 63 and 83: IP42
CLMD45, 65 and 85: IP54
CLMD33 / 33S: IP40
See capacitor nameplate for IP degree.
Installation and use
Indoor installation on firm foundation or fixed on a rigid
plate/frame in well-ventilated situations where the air
temperature around the capacitor does not exceed
35°C/95°F over one year, 45°C/113°F over 24 hours and
55°C/131°F (according to IEC 60831 Parts 1 and 2 for a -
25/D temperature category product).
CLMD13, 43, 53, 63 and 83 also exist in outdoor
execution. The temperature class is then -40/D according
to IEC60831. See nameplate for specification.
Exposure to sun may overheat capacitors. Special care
must be taken.
WARNING! The ambient temperature for capacitors
inside a cubicle is the temperature around the capacitors
and not around the cubicle.
WARNING! Like other standard capacitor units, CLMD
discharge devices are not suitable for use with rapid
switching rates (minimum off time: 40").
external resistors are not a solution for such cases. Only
specially designed capacitors must be used in such
applications.
Vertical and horizontal mounting
The CLMD capacitors must be fixed in such a way as to
ensure a natural airflow from bottom to top.
Minimum free space between units:
CLMD13: 20mm
CLMD33 / 33S: 25mm
CLMD43-45, 53, 63-65 and 83-85: 50mm
In case of vertical mounting, use a punched mounting
plate or support bars to allow free airflow between the
capacitors (Fig. #2). Do not mount upside down. (Fig. #3)
In case of horizontal mounting, install so that the natural
airflow goes between the units (Fig. #4). Do not mount so
that the natural airflow is blocked (Fig. #5).
Installation in a cubicle
WARNING! Guidelines only apply if the following limits
are respected:
- Maximum room temperature : 40°C (1 hour).
- Average maximum room temperature over 24 hours:
35°C.
- Average maximum room temperature over 1 year: 25°C.
When the capacitors are installed in a cubicle the
components should be placed in such a way as to
optimize the cooling. Do preferably place devices with
high heat dissipation above the capacitors to avoid
overheating them. When reactors are used they should be
placed in such a way that they do not radiate heat directly
on the capacitors. A thermal barrier is recommended.
Reactors do in general dissipate much heat, so their
thermal impact through convection must also be taken
into account.
1. Natural air circulation
The difference in height between air inlet and air outlet
should be large enough to improve the air circulation.
The airflow should be channeled in such a way as to
well cool the hottest spots in the cubicle. Air should flow
from the bottom to the top of the cubicle. The cross-
section of the top air outlet should be at least equal to
1.2 times the cross-section of the bottom air inlet.
