Do not install or remove a live power cable. Any contact between the power cable core and a conductor can
generate electric arc or sparks, which may cause fire or eye injury.
Connect the power cables correctly to the positive and negative terminals of the power supply device. The
recommended fuse capacity is 7 A to 10 A.
Do not connect the OAU 2F to an AC power supply device. Otherwise, the OAU 2F may be damaged.
Do not connect the OAU 2F to a DC power supply device providing power beyond the range of –38.4 V to –57.6 V.
