I
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.
 Disconnect power before connecting any wiring to IED-S.
 Even if the power has been turned off, a charge may still remain in the DC-link
capacitors with hazardous voltages before the POWER LED is OFF. Do NOT touch the
internal circuits and components.
 There are highly sensitive MOS components on the printed circuit boards. These
components are especially sensitive to static electricity. Take anti-static measure before
touching these components or the circuit boards.
 Never modify the internal components or wiring.
 Ground IED-S by using the ground terminal. The grounding method must comply with
the laws of the country where IED-S is to be installed.
 Do NOT install IED-S in a location with high temperature, direct sunlight or inflammable
materials or gases.
 Never connect the IED-S output terminals U/T1, V/T2 and W/T3 directly to the AC
mains circuit power supply.
 After finishing the wiring of IED-S, check if U/T1, V/T2, and W/T3 are short-circuited to
ground with a multimeter. Do NOT power IED-S if short circuits occur. Eliminate the
short circuits before IED-S is powered.

The rated voltage for IED-S must be  240V for 230V series (480V for 460V series) and
the mains supply current capacity must be  5000A RMS (  10000A RMS for the  40
HP (30 kW) models).
 Only qualified persons are allowed to install, wire and maintain IED-S.

Even if the three-phase AC motor is stopped, a charge with hazardous voltages may
still remain in the main circuit terminals of IED-S.

The performance of electrolytic capacitor will degrade if it is not charged for a long time.
It is recommended to charge IED-S which is stored in no charge condition every 2 years
for 3–4 hours to restore the performance of electrolytic capacitor in IED-S. Note: When
power up IED-S, use adjustable AC power source (e.g. AC autotransformer) to charge
IED-S at 70%–80% of rated voltage for 30 minutes (do not run IED-S). Then charge
IED-S at 100% of rated voltage for an hour (do not run IED-S). By doing these, restore
the performance of electrolytic capacitor before starting to run IED-S. Do NOT run
IED-S at 100% rated voltage right away.

Pay attention to the following precautions when transporting and installing this package
(including wooden crate and wood stave)
1. If you need to deworm the wooden crate, do NOT use fumigation or you will damage
IED-S. Any damage to IED-S caused by using fumigation voids the warranty.
2. Use other methods, such as heat treatment or any other non-fumigation treatment, to
deworm the wood packaging material.
3. If you use heat treatment to deworm, leave the packaging materials in an
environment of over 56°C for a minimum of thirty minutes.

Connect IED-S to a three-phase three-wire or three-phase four-wire Wye system to
comply with UL standards.

If IED-S generates leakage current over AC 3.5 mA or over DC 10 mA on a grounding
conductor, compliance with local grounding regulations or IEC61800-5-1 standard is
the minimum requirement for grounding.
