3.1.3. Ventilation
The MT5 Load Units dissipate the electrical energy from the modules as heat in the
form of warm air. It is critical that the MT5 Load unit have adequate ventilation that
allows cool ambient air to enter the front and exit the back of the load unit with minimal
airflow restriction. Raydec
recommends a minimum of 1 foot (12 “or 30 cm) of clearance
between the load fan intakes and exhaust, and surrounding surfaces.
Take care to avoid allowing the warm exhaust air to re-circulate to the fan intake. This
will cause the MT5 Load Unit to overheat requiring that it shutdown, and possibly
damage the unit.
Note: If operating the MT5 System inside an air conditioned area, the heat from the MT5
will add to the load on the air conditioning system. This will require the cooling system
work harder to remove this heat from the room. Or conversely, this heat will help warm
a room in winter months. The MT5 load dissipates all of the PV module power as warm
air, plus some small additional power from the load unit circuitry.
The MT5 Control unit dissipates little power and no special precautions or ventilation is
needed.
3.1.4. Connections
The MT5 has several specific connections and each is described below. The MT5
system comes with all the connectors needed. The manufacturer and part numbers of
each connector are listed in Appendix A.
Load Control
Each MT5 Control unit can control up to four MT5 Load Units. For a typical system with
one controller and one load, connect the load unit to the Load 1 port of the controller.
Use the 1-meter load control cable provided. Longer cables may be used if necessary.
Contact Raydec if you need a longer load control cable.
