Quantium 410 Installation Manual Installation
5.4.5 EARTHING
Earthing requirements are dictated by local National regulations and must always
be observed.
Tokheim recommends the following guidelines as a minimum requirement:-
• 6mm
2
earth conductor(s) back to main site earth (up to 85m cable run)
• 10mm
2
earth conductor(s) back to main site earth (85 to 150m cable run)
The primary earth connection point for Quantium dispensers is the M2000T
Junction Box provided for installation cable connections. Threaded inserts or
studs (M8) are also provided in the base frame as alternative or additional earth
connection points.
Earthing requirements are dependent upon the number of earth conductors
provided (one per power cable) and the types of cable used. For example,
where steel wire armour cables or MICC are used in conjunction with the
appropriate termination glands, no supplementary specific earth cable is likely to
be required. Where simple PVC covered cables are used, Tokheim recommends
an additional earth core is connected to the point provided on the dispenser base
frame.
IMPORTANT : It is the responsibility of the Installer to supply the
earth wire and ensure the dispenser is safely earthed.
The photograph below is an typical example of an earth connection point on a
Q410 dispenser :-
