Hochiki Europe (UK) Ltd Page 4 2-3-0-780/ISS8/DEC11 Installation – "Smart-Fix" Version  Set analogue address before installation (see page 1). The fixing surface should be dry and stable.  Hold the back plate up against the fixing surface and mark the position of the four corner fixing holes.  Determine which cut-out sections along the top and bottom edges of the module require removing to accommodate the cables being used.  Remove cut-outs by scoring with a sharp knife before breaking off with pliers or snips.  Mount the back plate using appropriate fixings (not supplied) for the fixing surface.  Terminate and connect field wiring as per the wiring diagrams on pages 2 & 3 (and the terminal block indications on the product label). The transparent lid (CHQ-LID) is supplied with four screws and eight retaining washers.  Push the screws through one of the retaining washers and then through the holes in the lid from front to back, pushing another retaining washer onto the end inside the lid.  Screw the lid onto the back plate; do not over tighten the screws as this could damage the unit. NOTE: A white plastic version of the lid is available (sold separately – CHQ-LID(WHT)). Fig 7 Installation – "Smart-Fix" with Back Box For those installations requiring glanded cables, a module back box (CHQ-BACKBOX) is available (sold separately). This features ten knock-out cable entries (glands are not supplied). Ensure glands used conform to IP67, if such ingress protection is required. The CHQ-BACKBOX is mounted on the fixing surface; the CHQ Module is then fitted to the top of the back box. Finally the CHQ-LID is added creating a sealed enclosure. For further details refer to the CHQ-BACKBOX Instructions (2-3-0-800).
