WIRING:
Risk of electric shock. PGV Series pump models do not come
with electric plug connectors. To reduce the risk of electric shock, be certain that it is
connected only to a properly grounded, grounding-type receptacle.
• Perform wiring conforming to National Electrical Code or to local electrical
codes. Failure to observe this caution may cause fire or damage to the
product.
• Make sure that the pump is rotating in the correct direction. Forward
rotation creates more pressure and discharge power than reverse rotation.
• For built-in automatic level control pump never take the float bracket to lift
the pump or pull the lead. Failure to observe this caution may cause injury
or damage to the product.
Do not alter the length or repair any power cable with a splice. The
pump motor and cable must be completely waterproof. Damage to the pump or
personal injury may result from alterations.
1. Voltage and frequency check- check whether the supply voltage and frequency
meet those indicated on the pump name plate.
2. Power connection- connect three wires U (red), V (white) and W (black) of the
power cable of the pump to a power supply unit at site.
a. Terminal E9 (green) is for ground use. Connect a grounding wire to this
terminal pursuant to the relevant law.
b. Also, provide electric leakage breaker.
3. Allowable cable length- keep voltage drop of the power cable with in 5% of the
specified voltage. Table 1 shows the allowable cable length subject to 5%
voltage down. (In case of 200V class)
a. The allowable cable length for the specified voltage 400V is four times the
values shown in Table-1.
