4. INSTALLATION
This product may only be installed by a qualified electrical engineer.
4.1 Location
The Quattro should be installed in a dry, well-ventilated location, as close as possible to the batteries. The device should be
surrounded by a free space of at least 10 cm for cooling purposes.
An excessively high environmental temperature has the following
consequences:
- shorter lifespan
- lower charging current
- lower peak power or inverter shut-down.
Never place the device directly above the batteries.
The Quattro is suitable for wall mounting. For mounting purposes, a hook and two holes are provided at the back of the casing
(see appendix G). The device can be fitted either horizontally or vertically. For optimal cooling, vertical fitting is preferred.
The inner part of the device should remain accessible after installation.
The distance between the Quattro and the battery should be as short as possible to reduce voltage loss across the battery
cables to a minimum.
Install the product in a heatproof environment.
Ensure therefore that there are no chemicals, plastic parts,
curtains or other textiles, etc. in the direct vicinity.
The Quattro has no internal DC fuse. The DC fuse should be
installed outside the Quattro.
4.2 Connecting the battery cables
In order to use the full potential of the Quattro, batteries of sufficient capacity and battery cables with the correct cross-section
should be used.

* '2x' means two positive and two negative cables.
Procedure
To connect the battery cables, follow the procedure below:
To prevent short circuiting of the battery, an isolated box wrench should be
used.
- Remove the DC fuse.
- Loosen the four lower front panel screws at the front of the unit, and remove the lower front panel.
- Connect the battery leads: + (red) to the right-hand terminal and - (black) to the left-hand terminal (see appendix A).
- Tighten the connections after mounting the fastening parts.
- Tighten the nuts well for minimal contact resistance.
- Replace the DC fuse only after completing the whole installation procedure.
