J PRECAUTIONS ON INSTALLATION & WIRING---------------------------------------------------------
A
caution
★ Do not connect any terminal on any unit to AC power lines to prevent fire or unit damage.
★ High voltage is present on the monitor unit inside. Do not open MYH-CUB without first unplugging the power
supply, to prevent electric shock.
★ Do not attempt to install or connect wires on MYH-CUB equipment while system’s power supply is plugged in.
★ MYH-CUB and related equipment, except door station, are designed for indoor use only. Do not install outdoors.
★ Do not connect any other power source than specified on terminals -r, -. Doing so can damage the MYH-CUB
equipment.
★ For system’s installation, there is no need to disassemble the equipment, except to open the unit for wiring. Do
not access the PC board or any components unless properly qualified.

★ MYH-CUB is an electrical device, which must not be subejcted to water, or any other liquid.
★ Weather conditions, such as lightning strorms, may cause damage to MYH-CUB equipment. We recommend that
power surge protection be installed as follows: (However, this does not guarantee that no damage will occur).
If the power supply has a GROUND terminal, take it to an earth ground. In this case, a separate surge arrester
is not necessary.
When using a power supply that has no GROUND terminal,
install a surge arrester near the output as shown.
