Wiring For Power Supply - Toho Electronics TRM20A Operation Manual

4.2 Wiring for power supply

Warning
Please energize to this equipment after doing the protection earth without fail for the
●
electric shock prevention.
Please do not cut the protective earth, and please do not remove connecting wires of the
●
protective earth.
Please confirm the power-supply voltage of this equipment is corresponding to the
●
voltage of the power supply.
Please energize to this equipment after applying the protection cover of the transparency.
●
When performing maintenance work, etc. , please start work from after 10 seconds turn
●
off the power.
CAUTION
Please use the one that corresponds to 600V vinyl insulation electric wire (IEC
●
60227-3) or it for the electric wire for the power supply.
Please install round shape pressure connection terminal (for M3.5) to which the
●
insulation sleeve adheres on the electric wire terminal.
Please connect the protective grounding terminal (resistance:100Ω or lower, minimum
●
diameter of a ground line 1.6 mm) to protective ground.
When you share the protective earth conductor with other equipment, the influence of
●
the noise from the ground line might be received. Sharing with other equipment is
recommended to be avoided.
For safety, please install the breaker or the switch, that conformed to EN60947-1 and
●
EN60947-3, within easy reach of the operator, and please indicate that these are the
breaker or the switch for power supply disconnection of this instrument.
The voltage rating must use the main source of electrical power in the variation range
●
in ±10%.
A transitional current might flow to the main source of electrical power when the
●
power supply is turned on.
［Power supply terminal］
Power supply terminal is "Terminal No. 51
［Wiring procedure］
The protection cover of the transparency of the terminal stand is removed. It pulls forward while
①
pushing the hook of two places of one side of cover part internally at the same time and it removes.
The cable is connected with the power supply terminal. The protective grounding is connected with
②
terminal No.53(G). Non-earth side of the power supply is connected with terminal No.51(L), and the
earth side of the power supply is connected with terminal No.52(N).
The protection cover of the transparency is installed.
③
It is confirmed that the protection earth is correctly done.
