    I'm doing a bit of DIY. Just purchased a Horsmann Electronic & to replace Hortsmann Quartz. It's a straight swap. You keep the old back box and wiring, remove old unit by pulling out the old push fit connectors and plug in the new unit.

    Installation instructions have me confused. Fig. 1 shows push fit connectors with the numbered and flat side up, graduated side facing down. In reality the flat side of the connectors are blank and the graduated side is the numbered one.

    I forget which way the old ones were inserted. Which way up do they go or does it not matter?

    Instructions: https://www.tlc-direct.co.uk/Technical/DataSheets/Horstmann/EL7_I.PDF

    Photo of actual connector attached.

    Surely they fit with the numbers upward. As shown in the instructions!

    But the problem is that instructions don't show the connector as it is in reality.
    See the photo and how it differs to Fig. 1 - the numbers are actually on the other side of the connector (the side of the connector which is not level).

    So, if I connect with the numbered side up, the orientation of the connector is the other way round compared to what is shown in the instructions.

    Ah. Ok. Yes the shape in the instructions shows the chamfered side goes down. Probably doesn’t matter, providing proper contact is made.

    I don't want to cause a problem. Has anyone swapped one of these out before and can confirm?

    Thanks. All connected and working.

    This was the answer from the manufacturer by the way:

    Thank you for your enquiry.

    With the spade connectors it doesn’t really matter which way they fit on as long as the numbers match i.e. 1 to 1, 2 to 2 etc. I would personally connect them chamfered side facing downwards as this is how it was designed to be fitted. The numbering is just an indicator of which plug and socket goes where.


    Best regards
