Installation Quantium 510 Installation Manual
5.6 Electrical Connections
During installation, the main switch must be switched off - ensure the main switch cannot
be switched on inadvertently.
The installation of the cables must be carried out carefully to ensure the Eex-norm is
enforced (insertion of cables via glands).
The electrical connections are compatible with all European installation practices and typical
country specific cable types. The following information is the Tokheim recommended
installation, however where differences exist in the standards relating to installation according
to country specific legislation, the local/national standards must be employed.
CABLING
The type of cabling used will differ by country according to local and/or national laws and
regulations. The drawings in this section show the minimum number of cores required in
cables and the minimum core cross sectional area. Cables with more than the minimum
can be used provided that the cables are suitable for use with the cable gland sizes fitted.
Individual cables can be combined provided that the minimum number of conductors remains.
The maximum number of forecourt cables required will be :-
• One power cable for motor power supply
• One power cable for calculator supply
• One/two cable(s) for dispener communications
• One cable for speaker (optional)
• One ethernet Cat 5 cable per side for OPT communications (optional)
• One ethernet Cat 5 cable per side for Vidium (optional)
• One cable per submerged pump control signals (where applicable)
ELECTRONICS AND LIGHTING PROTECTION
Tokheim recommends a 2-pole thermal-magnetic device for protection of the metering
pump electronics. A fuse must
NOT be used in the neutral conductor. Thermal-magnetic
Breakers or fuses must be capable of extinguishing a fault current of at least 4000A.
Note : Provision for lighting supply is not required as LED backlighting is standard.
MOTOR WIRING
The number of motors per dispenser will vary according to different models and options.
Always connect to the furthest left terminal first. Jumper sizes and positions will vary
according to the number of motors.
