CAUTION : For continued safety,
replace safety critical compo-
nents only with manufacturer’s
recommended parts (refer to parts
list).
Indicates safety critical com-
ponents. To reduce the risk of
electric shock, leakage-current or
resistance measurements shall
be carried out (exposed parts are
acceptably insulated from the
supply circuit) before the appli-
ance is returned to the customer.
• DC voltages are as measured
with a high impedance voltme-
ter. Values may vary slightly
due to variations between indi-
vidual instruments or/and units.
