5. Wiring Method
(1) The output load line and input line shall be separated to
improve noise sensitivity.
(2) The sensing lines shall be twisted and separated from the
output lines for remote sensing.
(3) Use all lines as thick and short as possible to make lower
impedance.
(4) Attaching a capacitor to the load terminals can eliminate
noise.
(5) For safety and EMI considerations, connect terminal to
the mounting set ground terminal.
(6) Recommended torque for the terminal;
HWS600 Output terminal (M5 screw): 2.50 N · m (25.5kgf ·
cm)
HWS300 Input, Output terminal & HWS600 Input terminal
(M4 screw): 1.27 N · m (13.0kgf · cm)

[The PHD connector manufacture method ]
This product is using SPHD-001T-P0.5 or SPHD-002T-0.5 con-
nector made from JAPAN SOLDERLESS TERMINAL MFG CO
LTD.
Regarding to manufacture of a connector, it becomes the regu-
lation as following.
a). Appricable Wire and Crimping tool
Wire size is AWG#26-AWG#22 and insulation outer dia is
φ1.0-φ1.5mm.
Appreciable wire per barrel size is UL1007 (standard wire) and
its equivalent standard wire can be used.
Regarding the AWG#22, use UL1061 or its equivalent standard
wire, because wire insulation outer diameter of UL1061 is samll.
Crimping tool is as below.
Crimping tool Crimping applicator Dies
AP-K2 or AP-KS MKS-LS-10 or MKS-L-10 SPHD-001-05/SPHD-002-05
b). Crimping Operation
The reference value of wire strip is 2.3mm. As wire strip length
diff ers depending on type of wire and crimping method, decide
the best wire strip length considering processing condition.
When wire is stripped, do not damage or cut off wire conducto-
res.

UL1007 AWG #24 1.5 0.62 - 0.67 1.8
Note 1. Crimp height at wire barrel should be set to pre-deter-
mined dimensions.
Note 2. Adjust crimp height at wire insulation barrel to the ex-
tent that wire insulation is slightly pressed, and set it so
that crimping is not excessivery.
Note 3. Crimping condition at wire insulation barrel is as below
Fig.1.
Note 4. For AWG#28, #26, #24, use UL1007 type. For AWG
#22, use UL1061 type.

c). Inserting contact into housing
Inserting crimped contact into housing
(1) Do not apply any pulling force to crimped part, and insert
contact parallel to housing
(2) Insert contact into housing without stopping to innermost
(3) Check secure locking per each insertion by pulling wire soft-
ly in order to check that contact does not come off housing.
Besides, check whether there is the backlash in the direc-
tion of insertion axis.

d). Mating and Unmating Connector
(1) Inserting connector
Hold receptacle housing securely and insert into header
straight against to header post until click sounds.
(2) Unmating connector
Hold all wires securely and fi x receptacle housing by fi ngers
so as to pry, and then, withdraw it on the mating axis.

e). Routing of Wire
Routing wire so as not to apply external force to connector ex-
cept force to such an extent that wire slightly buckles, consider-
ing an enough length to route and fi xing of wire.

Mounting Method
(1) Forced air cooling type power supply.
This power supply has ventilating holes on the front and
back side panels. Keep these two areas freely as much as
possible.
(2) The maximum allowable penetration is 6mm.
Incomplete thread of mounting screw should not be
penetrated.
(3) Recommended torque for mounting screw:
M4 screw: 1.27 N · m (13.0kgf · cm)
