The Pro-120 is designed for mounting via the

heatsink as in the diagram (facing page). This also

shows a section through the optional base and cover .

This mounting will normally be on to a metal chassis

which will act as additional heatsinking but, in most

applications, full current is only drawn for short

periods so little heating will be experienced.

However, the Pro's heatsink is a thick block of

aluminium which won't cool down quickly to the air

if it does get hot so some heatsinking should be used.

A suitable metal plate which will usually be the

vehicle's chassis.

For sustained high current use you must use a

substantial extra heatsink with heatsink compound

on the joint between the Pro's block and your

heatsink.The Pro 120's heatsink is not connected to

Pro-120 controller instructions

the rest of the circuitry. Mounting holes are tapped

M4.

Optionally a base/heatsink and cover is available for

the Pro-120 - see section 14.

Corner mounting holes are also present but we

recommend mounting only by the heatsink.

Whatever you do, make sure the controller can't get

wet and, if it does, don't connect the battery until

you have dried the controller thoroughly. The water

won't cause damage unless the unit is connected to

the battery, when electrolytic corrosion will occur.
