2 INSTALLATION GUIDE
2.2.1 Mounting the Main Unit
Do NOT expose the Main Unit to rain, snow, spray or bilge water. For optimum
operation, the BMS should be mounted where the temperature is nominally below
35°C and does not exceed a maximum of 60°C.
The Main Unit must not be installed in a location with any less than 10cm clearance
at the top of the Main Unit, to allow for airfl ow across the heatsink fi ns. Care must
be taken not to obstruct the ventilation holes at the end of the Main Unit.
The Main Unit should be installed as close as possible to the house battery. The
cable length should be less than 2m.
The Main Unit must be mounted to a solid support, preferably the vehicle chassis,
using M6 sized screws or bolts, using all four mounting holes.
WARNING
The Main Unit must be fi xed using suitable screw mounts. Do NOT use adhesive
to mount the unit because this is unreliable.
Redarc recommends that the Main Unit be mounted to optimise airfl ow past the
heatsink. Mounting the unit horizontally (see Figure 2.2.1.1) is acceptable. Do
NOT mount the unit as shown in Figure 2.2.1.2 or Figure 2.2.1.3.
