2000N Banknote Timer Handbook
Installation
Mechanical Installation
The Wyvern® 2000N timer should be mounted on a smooth vertical wall away
from corners so the cover lock can be easily accessed. The timer is 350 mm high
by 175 mm wide and has a depth of 140 mm so allow sufficient clearance for the
cover to swing down when opened. Take care to mount the case level in both the
vertical and horizontal axes; failure to do so may prevent correct operation of the
banknote acceptor. Choose an area where an ambient temperature of 40°C is not
exceeded, away from any source of moisture, dust or direct heat.
Open the case using the key supplied and position the case on the wall and mark
the position of the two upper keyhole slots. Plug the wall and fit two No. 8 or 10
screws of not less than 22 mm in length and hang the timer on these screws. Mark
the position of the lower two fixing screws and remove the timer and plug the wall.
Remove the required cable knockouts and fix the timer to the wall.
Electrical Installation
The timer will require a fused double pole switch for the mains input with a fuse
suitable for the load being controlled (maximum 5 amp). Using 20 mm conduit
with a male thread adaptor and lock ring, or a 20 mm nylon compression cable
gland to provide strain relief , wire the unit as shown in Figures 2 and 3. Use
appropriately rated and approved cable relating to the relevant regional standards
up to a maximum current of 5 amp. Remove the safety shield before connecting
any wiring and replace safety shield after all connections are secured.
It is essential that the safety earth is connected to a known good earth. Unless
double insulated the load must be connected to the same bonding point as the main
earth to ensure good noise immunity.

2000N is supplied as a voltage switching device - that is the
switched output is the same as the mains input voltage. In this case the load is
connected between pins 3 and 4. If a voltage free output is required (for example
to switch a device operating from a different supply) then the black link is
removed from between terminal block pins 5 and 6 and the load connected
between pins 3 and 5. See Figures 2 and 3.
NOTE. The Wyvern

2000N accepts mains voltages in the range 110V - 240V
50/60 Hz.
