weight of converter can be endured. Installation at an unsuited place may cause turnover or fall and
there is a risk of injury.
Before transport, fix the door so that it will not open. Otherwise, the casing may be separated and fall
to cause an injury.
During installation work, care should be taken to keep the unit free from entry of cable chips or other
foreign objects. Otherwise, it may cause fire, failure or malfunction.
3.1 Installation site
Install the converter in a place that satisfies the following conditions.
(1) Space for periodic inspection and wiring work is available.
(2) Vibration, dust, dirt, and humidity are minimal.
(3) A place not subjected to radiated heat from a heating furnace, etc.
(4) The atmosphere is non-corrosive.
(5) Away from electrical devices that may cause noise trouble (such as motor and transformer), and
equipment that may cause electromagnetic or electrostatic induction trouble.
(6) A place where ambient temperature and humidity are -20 to +55°C and 95%RH or less.
Secure at least 100 mm of space between the converter and nearby wall. Also secure a space of opening the
front cover for maintenance.
Secure a cable wiring space under the case.

4. WIRING AND PIPING
CAUTION
: Wiring work must be carried out with all power supplies turned off. Otherwise electric
shock may result.
: Be sure to ground the Converter. (Class D grounding)
4.1 Before wiring
(1) Power voltage for the converter must conform to that for the detector to be connected.
(2) Power supply wiring
Use 1.25sq 600V vinyl insulated cable (JISC3307) or equivalent as power supply cable.
Use the main ground wire longer than the L1 and L2 lines.
Fix the part of the AC cable sheath that is more inner than the cord bushing by 3 mm or more.
Use a solderless terminal for the end of the AC cable. For the main ground wire, use the solderless
terminal whose core wire and sheath are caulked separately (double caulking).
Connect the ground wire to the following:
M4 screw / round terminal of the main ground wire / tooth lock washer / casing
Note
• Use the cable more than 0.75mm
2
for main ground (earth) line.
• For solderless terminal , doubly caulk the core and the sheath
separately.
The core should be poked from 0.5 to 1.0 mm.
The core should be so as not to
be seen or not to be come apart.
The crimping (vary by tools)
should clearly be in the
normal place.
No space required between
the insulating material and
the wire.
• Use “ ” type of solderless terminal .
Attach the solderless terminals to
the grounding terminals with them
b
etween the tooth lock washer and
screw with washer .

(3) Provide adequate protection of the exclusive cable (6 cores in total), which connects the detector to
converter, using wire protection tube, etc. Separate these cables from the power cable (noise preven-
tion).
(4) Keep the wire for output signals as far as possible (more than 30cm) from the power line and heavy
current lines to prevent induced noise. Also, wherever possible use a shielded cable and earth one
point of the shield.
Note) For connection of the lines to the external terminals, use of ring crimp solderless terminal
with insulation sleeve is recommended.
