Mounting
Remove the subbase from the timer by depressing the
securing clip A and pulling the two halves apart. See fig. 1
The ST699 can either be mounted onto the wall surface or a
flush mounted UA1 (with 60.3 mm pitch mounting holes)
using the screws supplied.

Cable entries can be made through the opening in the rear of
the subbase, or via the three surface entry break-outs in the
top and two sides of the wallplate. See fig. 2
The ST699 is designed for fixed wiring only and must be
Ensure the wiring connections to the mains supply is via a
fuse rated at not more than 3 A and a Class "A" switch
(having contact separation of at least 3 mm in all poles).
Remove the terminal cover to allow access to the wiring
terminals as shown in fig.2. Connect the systems wiring as
shown by the specific applications wiring diagram. A
maximum of two 2.5 mm2 (cross sectional area) wires can be
connected to each terminal as shown in fig.3. Each wire
should be stripped of insulation to a length no greater than
7mm to safeguard against the possibility of electrical shorts.
