{If the rectifier with incorrect w:ring is employed,
the rectifier capabilities of the rectifier are immedi-
ately destroyed.
(2) Caution concerning voltage
At temperatures as high as l 50°C, the voltage
insulation in the reverse direction of the silicon
rectifier is not lowered. However, when the momen-
tum value over the reverse voltage insulation is
applied to the rectifier at low temperatures, the
current increases suddenly and the rectifying layer
is rendered unserviceable. As the value of voltage
insulation in the reverse direction is
1
00 V at all
times, one silicon rectifier should not be applied
to voltage exceeding l 00
V.
If
the silicon rectifier is used with no load at
the output side or with battery terminals discon-
nected, the maximum voltage value of the AC
generator becomes 200
V.
If this occurs, damage
to the recifying layer is caused at once. Acce-
leration should be avoided during repair.
(3) Concerning current
If
current of more than 5 A per rectifying ele-
ment exists, intense heat is generated which renders
the rectifier unserviceable. Therefore, excessive
current due to measurement or heat in the electrical
circuit should be avoided.
(4) Caution concerning assembly
With the cooling plates assembled, the two elec-
trodes of the AC current and the+ and- terminals
of DC current have different characteristics; shorting
these with tools such as a screwdriver must be
avoided. Upon installing the equipment to the body,
the cooling plate should not contact the body.
If the cooling plate is bent, or receives severe
shock, the connecting wire may be cut or the
protective ring may be damaged. If this occurs.
rectifying performance is stopped.

Silicon rectifier
Specifications
1. Rectiying characteristic
When AC terminals are connected acd 30 A Cetween
+
and - terminals flow in the forward direction,
voltage drop is less than 2 V between
+
and
terminals.
When 1 00 V in the reverse direction. the
reverse current flow should be below 0.1 ma.
2. Rated output current 8 A.
3. Double vibration performance. When normal instal-
lation, ii should endure the vibration, vertical
3600/minute, and maximum amplitude of 1.1 mm 1.04")
for 100 hours.
