NOTE: The plastic cable ties surrounding the air pump are to ensure safe handling during
shipping. Please remove before operation. Reinstall a plastic cable around the air pump if
the unit is shipped to Bacharach, Inc. for service or repair. This prevents damage during
shipping.
2.4. Electrical Wiring
The MZ monitor uses a universal power supply that is capable of accepting inputs of 100 to 240 VAC,
50/60 Hz. The monitor’s power consumption is 20 Watts. It is highly recommended that the monitor be
connected directly to the AC power source, preferably on its own circuit. The AC power connection should
be completed with UL listed 3-conductor wire (minimum 16 AWG), rated 300 VAC at 105°C.
Locate a convenient service knockout and install electrical conduit in the typical manner.
Locate the AC input terminals and ground stud on the inside of the monitor. Secure the incoming AC power
neutral (white/blue) and live (black/brown) wires to the LINE 1 and LINE 2 terminals.
Using the supplied crimp-on ring terminals, washers, and nuts, connect the incoming AC power ground wire
(green) to the monitor’s AC input ground stud, and then install a separate wire between the ground stud and
the GND terminal.
WARNING: Electrical installation should be performed by a certified electrician, and must
comply with all applicable NEC/CEC and local electrical safety codes.
