8.4.2 Clearance under the modules

■

Minimum clearance

NOTE

• Rooftop or freefield mounting

Ensure a clearance of at least 4 cm between the rear

edge of the frame and the mounting surface (e.g. the

roof tiles) for the rear ventilation ofthe aleo module.

• Roof-integrated mounting

Ensure an appropriate interval, for example, to the

trough of the mounting system. Also ensure ade-

quate ridge ventilation, for example, with a roof

ridge ventilator.

■

Maximum clearance

NOTE

• The largest permissible clearance is defined by

national standards. This is used to design the instal

lation on the assumed effects of wind and suction.

• The actual maximum clearance of an installation is

determined by the sub-structure. Ensure that your

sub-structure adheres to the permissible clearances.

8.5

Avoiding seals

NOTE

• Avoid the use of a seal between aleo modules and

their mounting surface.

• Dry and cool operation can have a positive effect on

the performance as well as the service life of an

aleo module.

• Also for roof-integrated mounting, ensure good rear

ventilation to minimise loss of output which results

from a higher module temperature. Ensure adequa-

te ridge ventilation, for example, with a roof ridge

ventilator.

8.6

Clearance under the modules

NOTE

• Keep the space behind the laminate free of any

objects. This prevents damage to the insulating

back sheet and the junction box.

• Ensure that sharp or conductive parts (e.g. screws

or nails) do not protrude into the space behind the

module.

• If possible, take measures to prevent foreign ob-

jects (e.g. snow, ice, leaves, twigs, branches) from

being able to get behind the module.

9.1 Connectors

WARNING!

Incompatible or unsuitable connectors can

overheat. Fire hazard!

• Only use connectors that are the same type and

from the same manufacturer.

• Avoid using different types of connectors or ones

from different manufacturers, even :

- if connecting is possible

- if the connectors have the same basic designation

(e.g. "MC4") or

- if they are designated as "compatible".

_______________________________________________

You can find more details on this in the next two sections.

9.1.1 Module connectors

The various module types can be fitted with the following

connectors:

• Original Multicontact

• PV-JM601 (with locking)

You can find the specific connectors in the module data

sheet.

9.1.2 Connector peculiarities

NOTE

• Original Multicontact® MC4 connectors

• Only plug original Multicontact

connectors into original Multicontact

connectors.1

• PV-JM601 connectors

• Only plug PV-JM601 connectors into PV-JM601

connectors.

9.1.3 Replacing the connectors

You can remove the connector on a module and replace it

with another connector, if necessary. You retain the manu-

facturing warranty if you remove and mount with approved

tools in the proper way and according to the connector

manufacturer's instructions.

The original Multicontact® MC4 connectors are referred to as "MC4" in the data sheet.
