Installing the System
Input Power Condition
The input power of the SMG-400 system needs to be supplied with the AC power.
You should use the consent that supplies normal AC only for the SMG-400 system. This consent
should not be used parallel with other devices. This consent should be located at a safe place to
prevent cutting off the power by mistake.
You should choose the power outlet suitable for the SMG-400 capacity.
The standard of the SMG-400 system is
y
Input : AC 110-240V
y
Output : -48V(25W), +5V(10W), +3.3V(15W)
Line Condition
You need to
take
careful
note of the following
when install
ing cables
.
y
When wiring at a place where there is high humidity, take steps to reduce this to acceptable
levels
before proceeding
with
the work.
y
Take care of the cable to prevent it from being deform
ed
or damage
d
.
y
Make the line’s curvature radius to be 6 times larger than the cable’s circumference where there
have no repeating curved points.
y
You must take extreme precaution in the cable’s insulation overlap cases where the copper wire
are exposed and get entangled.
y
The maximum allowable line’s loop resister is not more than 1.8KOhm. The line’s leak resistor
must be over 20KOhm, the earth’s leak resistor must be over 20KOhm. (These conditions may
be ignored only in special cases.)
y
Do not place the line near a high voltage power line.
