7-2 EXAMPLE FOR THE WHOLE SYSTEM
7-3 POWER CIRCUIT, SAFETY DEVICE AND CABLE REQUIREMENTS
•
A power circuit (Refer to Table 3) must be provided for connection of the unit. This circuit must be protected
with the required safety devices, i.e. a main switch, a slow blow fuse on each phase and an earth leakage
circuit breaker.
•
When using residual current operated circuit breakers, be sure to use a high-speed type (0.1 second or
less) 30mA rated residual operating current.
•
Use copper conductors only.
•
Use insulated wire for the power cord.
•
Select the power supply cable type and size in accordance with relevant local and national regulations.
•
Use vinyl cord with sheath or cable (2 wire) of AWG 18-16 for transmission wiring.
