Power Supply Cable and Connector
The power cable and connecter are to be prepared under your responsibility,
referring to the following table.
Power supply Cable
Table 3-3 Power Supply Cable and Connector
Cable and Connector
Types (for your system)
Cable
3 wires, thicker than 14AWG, includes ground.
Power Supply Connector
IEC60320 C-13 equivalent
10A cable mount female connector
z
Only qualified personal are allowed to install wiring.
z
Be sure to turn OFF the power prior to wiring to assure safety.
Do not do any wiring when the system is energized.
z
The system wiring requires not only a through connection with the
designated cable but also securing to prevent loose connection.
Poor connection and securing may cause electric shock, heat spots,
fire, or communication errors.
z
Be sure to supply the power to this product according to the
specification.
z
Always establish a connection to a ground for safety.
z
Be sure that no ground connection is made to a water pipe, gas pipe
and lighting rod.
z
Be sure to provide protective ground. IEC protection
class of the product is class I. Be sure to provide protective
ground (ground resistance of 100
Ω
or less). Grounding can be
provided via the PE line of the power supply cable. For details
of the power supply cable, refer to page 3-5, Power Supply
Cable and Connector
z
Do not use the same ground being used by equipment
that generates strong electrical magnetic noise or high
frequencies
