Mounting Gen4
Location
The mounting location for the controller should be chosen with care taking into account the
following considerations:-
Do not mount the controller on the outside of a vehicle where it would be assessable to
unauthorized personnel (for the purposes of UL, the controller enclosure is not
considered to be the 'ultimate enclosure' and should be sited within another enclosure).
Do not mount the controller where it may be susceptible to damage due to minor
collisions, impact from road debris or chemical contamination (see 'Protection from
chemical contamination' below).
Although the controller has a high degree of ingress protection the electrical power
terminals do not. Avoid mounting the controller in locations where it may be submerged
in water or subjected to long term exposure to jets of water or exposed to potentially
conductive contamination and or debris.
Take note of the thermal and EMC considerations as explained later in this section of the
manual.
Protection from chemical contamination
The Polycarbonate cover of Gen4 controllers are designed for good all-round protection of the
electronics. However the controller should be sited so it cannot come into contact with significant
quanties of industrial chemicals. The following have shown to be damaging to the cover:-
Most esters (contained in some 'bio' hydraulic fluid such as Shell Naturelle HF-E)
Most industrial alcohols (contained in some contact grease such as Electrolube CG53A)
Electrical terminals on the controller present an electric shock hazard. High currents can
also present a burn hazard. You must ensure that the electrical terminals of the controller
are protected against access by unauthorized personnel.
Orientation
The controller can be mounted in any orientation.
Clearance for LED access
If you want an operator of your vehicle to be able to view the onboard LED, it is advisable to
consider the line of sight to the LED at this time.
