temporarily.

WARNING:
When connecting or removing
the quick-disconnect power plug
to any Smart Block, it is neces-
sary to ensure that there is no
power present at the plug itself.
Remove power at either the cir-
cuit/bay fuse or remove the fuse
from the Smart Block itself be-
fore connecting the power plug.
Failure to do so will cause dam-
age to the Smart Block and may
void any Dantel warranty.
