ADDITIONAL SERVICE AND
MAINTENANCE FOR IDH MAX
LOCKS
This chapter contains instructions for replacing
IDH Max components such as wire harnesses, card

Note: When replacing components, always test that
the lock works properly when you’re finished.

lock, make sure that you remove power from the
lock.

component on the circuit board, make sure that
you are properly grounded using an electrostatic

board without proper grounding can damage
