alternative mains supply must be provided, being careful not to compromise the safety
of the controller. A suitable disconnect device must be provided for this supply. (Refer
to Poole Engineering if in doubt).

after installation, this fuse should be removed and stored in a safe place, ready for
insertion during commissioning.
