5 Operational & Safety Information
5.1 Connecting to the Mains supply - Safety checks
For your safety it is
IMPORTANT
that you follow these connections instructions each time your Leisure
Vehicle is connected to a mains supply.
A)
Ensure suitability of the Mains Supply
. Your Leisure Vehicle should only be connected to an
approved supply that meets the requirements of BS7671. In most cases the site warden will hold
information regarding suitability of supply. If using a generator you also need to comply with the
requirements / instructions supplied with the generator. Please note that some electronic
generators may not be compatible with your leisure system.
B)
Switch the EC155PSU internal Power Converter OFF
. Locate the red ‘Charger’ power switch on
the EC155PSU and ensure the switch is in the OFF (0) position before connection to the mains
supply.
C)
Connect the Hook-up Lead
. Firstly connect the supplied hook-up lead (orange cable with blue
connectors) to the Leisure Vehicle and then connect to the mains supply.
D)
Check Residual Current Device operation
. Locate the RCD within the EC155PSU and ensure
the RCD is switched on (lever in up position). Press the ‘TEST’ button and confirm that the RCD
turns off (lever in down position). Switch the RCD back to the on position (lever in up position). If
the test button failed to operate the RCD see section 5.2.
E)
Check Miniature Circuit Breakers
. Locate the MCB’s within the EC155PSU (adjacent to the
RCD) and ensure they are all in the ON (up) position. If any MCB’s fail to latch in the on position
see section 5.2.
F)
Turn the EC155PSU ON
. Locate the red power switch on the EC155PSU and turn to the ON (I)
position. The switch will illuminate when turned on.
G)
Check operation of equipment
. It is now safe to check the operation of the 12V and 230V
equipment.
