V600-12 String Optimizer Platform
Installation Manual: 57070013-1 H
Handling and Storage Best Practices
•
Store optimizers in a clean, dry area that is protected from weather exposure and pooling water (-30 to 80°C.
Relative humidity < 80%).
•
Leave the product in its original packing box until you are ready to install.
•
Do NOT stack pallets.
•
Do NOT lift, carry, or otherwise handle the optimizers by their connectors.
•
Leave connector caps in place until the optimizers are ready to be connected to protect the optimizer from
water and debris ingress.
•
Do NOT transport optimizers that are removed from original packaging. If the original packaging is no longer
available, use a similar box to protect the connectors and heat sink fins.
Mounting Best Practices
•
Ground the String Optimizer according to your local codes.
•
Verify that the optimizer is adequately grounded using continuity tester.
•
Do NOT mount optimizers with connectors facing upwards.
•
Leave space between mounted optimizers to allow for air circulation and cooling.
•
Ensure sufficient spacing so that maintenance personnel can read the optimizer faceplate, safety icons, serial
number, model number, and bar code label.
•
Keep optimizer free from pooling water.
•
Do NOT mount optimizers directly to a solar module frame.
•
Do NOT drill into optimizer frame to expand mounting holes.
•
When possible, mount optimizer in a location protected from the elements.
•
If using wireless communication, keep the antenna (located on the opposite side of the connectors) clear from
obstructions. Line of sight from the optimizer to the Ampt Communication Unit (CU) is recommended.
See Ampt CU manual for more information.
•
Leave connector sealing caps in place until the optimizers are ready to be connected to the PV string.
Electrical Connections Best Practices
•
Use only Amphenol mating connectors on input and output wires that are connected to optimizer.
•
Only use Amphenol H4 crimping pliers with the appropriate crimp range on cabling and connectors.
•
Do NOT cause lateral strain on the optimizer bulkhead connectors. Make sure there is enough slack on the input
and output wires to avoid strain. If installed on a tracker system, keep wires free from abrasion and leave
enough slack in the wires to account for tracker movement.
•
Test voltage and polarity of input strings and optimizer output before connecting.
•
Ensure there are no ground faults on input strings.
•
Do NOT operate optimizer with only one input.
•
Connect in the following order: Input B, Input A, Output.
•
If the output cable is already energized (not isolated), verify that the optimizer output voltage and output cable
share the same potential and polarity.
•
Configure inverter settings appropriately according to the project design.
•
Do NOT disconnect under load.
•
Always use a current clamp to ensure there is no current present before disconnecting outputs/inputs.
•
Disconnect in reverse order (Output, Input A, Input B) using an Amphenol unlocking tool for H4 connectors. (e.g.
Amphenol p/n: H4TU0000)
