2 900 Watt Passive Shunt Module
Installing the Shunt Orientation and Clearance
The following enclosure restrictions must be considered because the
shunt module dissipates excess regenerative power in the form of
heat. Refer to Figure 1 on page 2 and Figure 4 on page 9 for shunt
module spacing requirements.
Figure 1
Shunt Module Spacing Requirements Within an Enclosure
Do not mount temperature
sensitive components above
shunt module
155 mm (6.1 in.) min. of clearance
above the shunt module.
155 mm (6.1 in.) min. of
clearance on each side of the
shunt module.
155 mm (6.1 in.) min. of clearance
below the shunt module
Do not mount shunt module
on its side
155 mm (6.1 in.) min. of
clearance on each side of the
shunt module.
ATTENTION
!
The shunt module can release a large amount of heat
over time.
Any materials above the shunt module or its
enclosure may need the protection of a metal plate
to keep from deteriorating.
Failure to observe this precaution could result in
damage to surrounding materials, possibly leading to
fire.
ATTENTION
!
The shunt module can release a large amount of heat
inside an enclosure.
Ensure there is enough ventilation so as the
maximum ambient temperature of 50° C (122° F) is
not exceeded.
Failure to observe this precaution could result in
damage to the shunt module.
