Installation instructions

Please read these instructions fully before commencing work. The OP-DFST must be installed by a qualified person, in accordance with best practise and current IEE wiring regulations. Do not install the timer onto a flammable surface, or keep stored materials too close. The installed timer should have clearance of at least 150mm in all directions.

Ensure the supply is switched off. In addition, re- move any fuse protection or turn off the circuit break- er. The OP-DFST is designed to be installed onto a flush or surface-mounted electrical back-box of mini- mum 16mm depth. A BS1362 13 Amp cartridge fuse is pre-installed as circuit protection for the radial, or spur connection.

Make sure that the total load on the circuit - with the additional < 13A load connected to the fused spur timer - does not exceed the capacity of the circuit cable, fuse or circuit breaker.

Installation

Connect the incoming supply, and the outgoing load with the wiring diagram (Figure 1.). Use the earth continuity terminal which will be provided in a metal patress box, or the supplied screw terminal connector if using a moulded surface mounted box. Bare earth conductors must be sleeved. A flexible cable outlet, with cable restraint is provided. If the flexible cable outlet is required, remove the blanking cover and route the flexible load cable via the cable re- straint and the outlet hole. Check that all conductors are correctly connected, and terminals are fully tight- ened.

Secure the connected timer to the back-box with the 25mm machine screws provided. Make sure that cables are carefully routed and stowed to avoid pinching, stress or damage.
