INSTALLATION AND ASSEMBLY
(12) Power Supply
1 Power supply voltage
The guaranteed voltage of this system is ±10% of the rated voltage.
But if the impedance of the power wires is high, the voltage waveform will become distorted and show the same
symptoms as when voltage drops abnormally. As the following must be noted even if the voltage is within the
allowable range, check the power wiring again.
¶ The voltage drop from the switchboard to this system is great.
¶ The voltage changes greatly when the power of the system is turned on and off (Roughly 5% of the rated
voltage)
2 Power capacity and connection
This system is provided with one AC INLET each for units R and L. Referring to the current capacity below,
connect a switchboard with sufficient capacity for the left and right lines separately (the current increases when
the voltage drops).
When connecting the same line (same switchboard) to other devices, take note of the power consumption of the
other devices and make sure that the capacity of the switchboard is not exceeded.
3 Outlet Plug
The power supply cable of this system is provided with a outlet plug with grounding (2E) to prevent electric
hazards caused by current leakage.
Be sure to connect the plug to the outlet with grounding (2E).
4 Leak Breaker
The system is incorporated with the power line filter to reduce noise. For this reason, a leaked current of 2.0 mA
may flow through unit R (including MVP) and 1.0 mA through unit L (no MVP). If a current leakage breaker is
provided, check that the sensitivity current is above the total current leakage of the system.
Also calculate each unit such as image transmission unit, etc. as 0.5 mA.
Be sure to connect directly to the power supply on the cabinet panel to prevent voltage drop, deformation of the
current waveform, and noise inductance.
It is extremely dangerous to supply power from existing wall outlets, etc.
Install the system near the outlet for connecting the units of the system as much as possible.
Set the current capacity slightly greater-about more than 25% of the total consumption power.
