IMPORTANT SAFETY INSTRUCTIONS
The SUNSIEL Grid-Tied Photovoltaic Inverter (hereinafter known as SUNSIEL) is
designed and tested according to international safety requirements, but as with all
electrical and electronic equipment, certain precautions must be observed when
installing and/or operating the SUNSIEL. To reduce the risk of personal injury and to
ensure the safe operation of the SUNSIEL, you must carefully read and follow all
instructions, cautions and warnings in this guide.
WARNING: Limitation on Use
The SUNSIEL is not intended for use in connection with life support
systems or other medical equipment or devices.
WARNING: Shock Hazard
Before operating or performing maintenance on the SUNSIEL, read
all instructions, safety information, and all other appropriate sections
of this manual. Failure to adhere to these warnings could result in
severe shock or possible death. Exercise extreme caution at all times
to prevent accidents.
WARNING: Shock Hazard
The SUNSIEL enclosure contains exposed hazardous voltage
conductors. The SUNSIEL enclosure covers should remain in place
and should be secured by all of the mounting screws, except during
maintenance or testing.
These instructions are for use by qualified personnel who meet all
local and governmental code requirements for licensing and
training for the installation of Electrical Power Systems with AC and
DC voltage up to 1000 volts. To reduce the risk of electric shock, do
not perform any installation or servicing unless you are qualified to
do so.
WARNING: Shock Hazard from multiple locations
In order to remove all sources of voltage from the SUNSIEL, all
sources of incoming power must be de-energized. To fully remove
AC power, you must open the main utility circuit breaker. By only
opening the SUNSIEL AC disconnect switch (breaker), the parts at
the inverter AC output terminals remain energized.
To completely de-energize the PV input circuit(s), you must open all
fields PV disconnect switches or remove all PV string fuses in all field
PV combiner boxes. By only opening the SUNSIEL PV disconnect
switch(es), the parts at the inverter's PV input terminals remain
energized. Review the system configuration to determine all of the
possible sources of energy.
In addition, allow five minutes for the internal DC bus capacitors to
discharge after removing power and before removing the covers.
IV363 REV01. SUNSIEL PV Inverter Maintenance Manual

SIEL America
WARNING: Shock and Crush Hazards
If there is a PV array ground fault in the field, as indicated by the
SUNSIEL display panel, normally grounded parts and conductors of
the inverter, arrays, and other PV equipment may be ungrounded
and energized at hazardous voltage, even when the integral and
field PV disconnects are opened and PV string fuses are removed.
WARNING: Burn Hazard
The SUNSIEL contains internal components that become hot during
normal operation. Be extremely careful not to touch any internal
components during maintenance or testing if the unit is still at
operating temperature.
CAUTION: Risk of Overheating
The SUNSIEL incorporates an air intake and two exhaust air areas,
which must remain unobstructed during use. Failure to follow
clearance requirements around the unit can result in the inverter
overheating, leading to reduced output or to shutdown.
CAUTION: Risk of Damage Due to Static Discharge
Sensitive electronics inside the SUNSIEL can be destroyed if touched
by an electrostatically charged person or object. Follow proper
electrostatic discharge (“ESD”) protection procedures when working
on the inverter.

General Safety Precautions (for installation and operation)
1. Obey all applicable worker safety codes and regulations. Never work alone
when installing this equipment. A team of two workers is required until the
equipment is properly closed and secured.
2. When installing the SUNSIEL use only components recommended or sold by SIEL
America. Doing otherwise may result in a risk of fire, electric shock, injury to
persons, and will void the warranty.
3. Do not attempt to install the SUNSIEL if it has been dropped, or received more
than cosmetic damage during transport or shipping. If the SUNSIEL is damaged,
or suspected to be damaged, see “Warranty and Return Information”.
4. Before installing and using the SUNSIEL unit, read all instructions and cautionary
markings on the unit and all appropriate sections of this manual. Be sure to read
all instructions and cautionary markings for any equipment used as part of the
installation of this unit.
5. To avoid a risk of fire and electric shock, ensure that existing PV plant wiring is in
good condition and that the wire is not undersized. Do not operate the SUNSIEL
in conjunction with damaged or substandard plant wiring.
6. Do not disassemble the SUNSIEL as it contains no user-serviceable parts. See
Warranty for instructions on obtaining service. Attempting to service the SUNSIEL
yourself will void your warranty and may result in a risk of electrical shock or fire.
7. Use insulated tools to reduce the chance of short-circuits when installing or
working with the SIEL or a PV array. Thoroughly inspect the equipment prior to
energizing. Verify that no tools or equipment have inadvertently been left within
the system.
8. Several diagrams contained within this manual are basic in nature and are
included only to depict different installation options. All details may not be
shown, and as such, local and all applicable electrical codes must still be
referenced.
9. The SUNSIEL unit is designed and certified for full power operation at ambient
temperatures up to 122 °F (50 °C). Operation above this limit may result in
reduced output or SUNSIEL shutdown.
Safety Equipment
Authorized service personnel must be equipped with standard safety equipment
including the following:
•
Safety glasses
•
Steel-toed safety boots
•
Safety hard hats
•
Padlocks and tags
•
Appropriate meter to verify that the circuits are de-energized (1000 VAC and
VDC rated, minimum)
•
Check local and national safety regulations for other requirements
IV363 REV01. SUNSIEL PV Inverter Maintenance Manual

SIEL America
Lockout and Tag/Isolation Procedure
Safety requirements mandate that this equipment must not be serviced while
energized. Power sources for the SUNSIEL must be locked-out and tagged prior to
servicing. A padlock and tag should be installed on each energy source prior to
servicing.
WARNING: Shock Hazard
Review the system schematic for the installation to verify that all
available energy sources are de-energized. DC bus voltage may
also be present. Be sure to wait the full five minutes to allow the
capacitors to discharge completely.
The SUNSIEL can be energized from both the AC source and the DC source. To ensure
that the unit is de-energized prior to servicing, lockout and tag the SUNSIEL using the
following procedure.
1. Turn off the exported power using the STOP button on the touch display
2. Turn the SUNSIEL AC disconnect to the OFF position.
3. Turn the SUNSIEL PV disconnect switch to the OFF position.
4. Open, lockout, and tag the AC power at the utility circuit breaker.
5. Open, lockout and tag all PV field disconnect switches. If PV field disconnect
switches are not used, pull all PV string fuses in all PV string combiner enclosures,
lock and tag all PV combiner enclosures.
6. Using a voltmeter that has been verified to be functioning properly by testing it
on a known source, verify that all power to the SIEL is de-energized. Check the
following locations :
·
AC Utility Terminals
·
PV Terminals (both section in case of 250kW Unit)
