Mounting Dragon8

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 accessible to
unauthorized personnel (for the purposes of UL, the controller enclosure is not considered to be
the 'ultimate enclosure' and as such it 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
are exposed. Avoid mounting the controller in locations where it may be submerged in water,
exposed to jets of water, or exposed to potentially conductive contamination and/or debris.
•
Blocking the breather vent (see below) may lead to damage to the controller housing or allow
water ingress

Protection and Chemical Contamination

The covers of Dragon8 controllers are designed for good all-round protection of the electronics.
However the controller should be sited so that it cannot come into contact with significant quantities of
industrial chemicals. The following have shown to be damaging to Dragon8 covers:-
•
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.
