Interconnecting wiring
The program panel is connected to the base unit via
a set of pre-wired 4 core screened cables with pre
-wired plugs as shown.
Interconnecting wiring is via a 4 core screened cable
with pre-wired plugs, supplied in 2, 10, 20, 30, 50 and
100m lengths.
It is recommended that this control cable is run sep-
arately within its own trunking to avoid external inter-
ference.
Optional wiring

wired via normally open contacts to terminal pair
‘TIMER’. (Contacts closed to enable). Remove
factory fitted jumper J1.
** Door switch to be volt free and wired via normally
closed contacts to terminal pair
‘DOOR’. (Contacts
open to enable door mode). Remove factory fitted
jumper J2. refer section 10.2.6.1 - Door link settings.

Protection
There are two high speed fuses on the base unit to
protect the switching thyristors for the heater. An
external circuit breaker with the appropriate rating
should be installed for the protection of the installation.
