Lock-Out Tag-Out (LOTO) Procedure
Lock-out refers to the practice of preventing de-energized circuits from being reenergized by putting locks on the disconnecting devices, holding them open.
Tag-out refers to the practice of attaching a tag to the disconnect-device locks
warning others not to operate the disconnect device and containing information
relating to the lock-out, such as the person responsible, the reason, and the date
and time. Combined these two practices are called the lock-out and tag-out
(LOTO) procedure.

Introduction
DC Switch
The DC Switch is both the main power switch and a protective component which
is used to safely disconnect DC power between the PV array and the PV Inverter
whenever necessary to do so.
The PV Inverter operates automatically (without the need of switching On or Off)
when DC input and AC output requirements are continuously met. Turn the DC
switch to the Off position only to stop PV Inverter operation when a ground fault
condition is detected or when there is a non-ground fault condition to stop
inverter operation such as maintenance and servicing.
WARNING
ELECTRIC SHOCK HAZARD
• Do not perform maintenance and servicing without totally disconnecting
the DC source from the inverter. The DC switch does not de-energize the
DC fuse circuits. The fuse circuits remain live even if the DC switch is
turned to the Off position.
• To remove power to the inverter, disconnect power from the PV disconnect
device. See “Single Line Diagram for CL-60” on page xi.
• Alternatively, to remove power to the inverter, open all MC4 type connectors
using a special tool for disconnection.
Failure to follow these instructions can result in death or serious injury.
NOTE: For CL-60A, the DC switch is provided with a lockable twisting knob to
meet the NFPA 70E standard.

975-0768-01-01 Rev G
Technical Features
Over-temperature Derating High ambient temperature, a blocked fan, or poor
ventilation will initiate inverter power derating.
When the temperature inside the unit exceeds the upper limit, the inverter will derate
its power output until the internal temperature drops within the allowable range.

NOTE: The lower limit of the over-temperature derating is 75% of nominal power.
If both the module and internal temperatures reach power derating conditions, the
inverter will derate the power output based on the lower temperature between the two.
Figure 1-9 Over-Temperature Derating
Grid Under-voltage Derating When grid voltage is low, the inverter will derate
the output power to make sure the output current is within the allowable range.
Once the grid voltage is within Vmin (215V), the inverter will derate its output
power.

Introduction
PV Over-voltage Derating The inverter regularly scans the PV voltage every 25
minutes and forces the PV to derate to test whether the maximum power point is
less than 860 volts.
At 66 KVA, if the maximum power point is higher than 860 volts, then the inverter
will return to the higher voltage limit before it starts derating.

Grounding the Inverter
WARNING
ELECTRIC SHOCK HAZARD
Do not ground either DC positive or negative poles of the PV string. The
Conext CL-60 PV Inverter does not isolate the PV from the grid.
Failure to follow these instructions can result in death or serious injury.
Grounding System Overview
In this PV system, all non-current carrying metal parts and device enclosure
should be grounded (such as the PV array frame and the inverter enclosure).
When there is only one inverter in the PV system, the PE cable must be
grounded.
When there are multiple inverters in the PV system, they can be grounded at
multiple points. Connect the PE cables of all the inverters and the mounting metal
frames of the PV array to the equipotential cable (depends on the situation at the
site) in order to establish an equipotential connection. See Figure 3-5.

4. Store the PV Inverter according to the guidelines below.
•
Inverter must be packed inside its original carton with the desiccant
bags inside.
•
Store the inverter with its front panel facing up. The carton should lay flat
and parallel to the ground.
•
Seal the carton with standard packaging tape.
•
Store the inverter in a dry and clean place to protect it against dust and
moisture. See notice below.
•
Relative temperature: -30 to 85 °C (-22 to 185 ºF)
Relative humidity: 0 to 100%.
•
Do not stack more than two inverters (carton) together.
•
Keep the inverter away from chemically corrosive materials.
•
Periodically check for any visible damages to the carton and inspect the
inverter right away if the carton shows signs of penetration during the
storage period. Replace the carton, if necessary.
NOTE: A thorough and professional inspection may be required before reinstalling the inverter after more than six months in storage. Contact an
authorized installer.
