2-6. Caution on mounting the unit in a rack
When mounting the unit in a rack, use one of the following attachments:
・
Rack mount adapter RM-608J (for JIS rack)
•
RM-608E (for EIA rack) and rack mount frame attachment RJ-608-1/2 (for 1/2 rack width)
•
RJ-608-1/3 (for 1/3 rack width)
When mounting the unit in a rack, replace the screws on the left and right sides of the unit (two on each side) with the
flat countersunk head screws (N32-3006-41) that are included with RJ-608-1/2 or RJ-608-1/3.
When mounting the unit in a rack, remove the screw for the protective grounding terminal on the bottom face of the unit.
For your own safety, make sure to securely connect the rack to the ground before using the unit.
2-7. Connecting the Power Cable to the Primary Power
Be sure to turn off the power switch before connecting the power cable to the AC outlet or distribution panel.
Because the voltage rating of the supplied power cable is 125VAC, you must use a different cable when a power
voltage greater than 125VAC is used.
Plugging the power cable into an outlet or distribution panel that is not properly
grounded may result in electric shock or fire. Be sure to ask a qualified engineer to
connect the power cable to the distribution panel.
●
Connecting 400W and 800W models
Be sure to plug the supplied power cable into an AC outlet with earth ground.
●
For 1200W models and when connecting to the distribution panel
・
Strip the coating off the supplied power cable and connect round crimp-style terminals that fit the distribution
panel.
・
Connect the power cable, with the round crimp-style terminals attached to the wires, to the grounded distribution
panel, making sure that L, N, and G wires are properly connected.
The wire colors of the power cable must be as follows:
G
Green or green/yellow
N
White or light blue
L
Black or brown

2-8. Installation Environments
・
If the unit is used in a hot place and the internal temperature of the unit rises, the built-in overheat protection circuit
activates and turns off the output. Do not use the unit in a location where the grill in the front panel or air outlet port
in the rear panel is blocked. Blocking these ports will cause the internal temperature to rise. Maintain sufficient
distance between these ports and objects. In some conditions, hot air may blow out of the air outlet port in the rear
panel. Be careful.
・
Do not use the PS-A power supply unit in a place with a lot of dust or corrosive gas. These substances can cause
the product to deteriorate.
・
Do not use the unit on an incline or a place subject to vibration. Doing so can cause the unit to fall off the rack or fall
over, which may result in damage to the unit or personal injury.
