Din rail timer contactor wiring

Got a call out to a pub today, outside lights weren't working. What a mess the wiring is, as usual done by a large 'reputable' electrical contractor! DB for externals fed from supply side of switch on another DB, blanks missing from, no grommets in it 6mm Earth for the 25mm tails feeding the DB for outside lights and to top it off 0.75Mohm insulation resistance on the armoured supplying one set of lights. They done an EICR in April and gave it 5years! I've sorted the DB supply, the Earthing issue and isolated the circuit with the poor resistance reading pending further action, fitted a 25A 30ma RCD into the outside DB (there was just a 100A DP switch) however I've got a din rail mounted timer and contactor to fit in an outside DB, someone had been playing and they were all out in a box when I got there, I've not come across these before and to be quite frank I'm a bit miffed with the wiring of them, could anybody please point me in the direction of some diagrams etc, none of the terminals are marked at all on either of them. I'm not a maintenance man messing about I'm a fully qualified spark with a tired brain :confused5:
