Safety Information
This section contains safety information that must be observed at all times when working on or with the product. To prevent personal injury and property damage and to ensure long-term operation of the product, read this section carefully and observe all safety information at all times.

Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the DC conductors and the live components of the inverter. Touching the DC conductors or the live components can lead to lethal electric shocks. If you unplug the terminal plate plate with the connected DC conductors from DC-in slot under load, an electric arc may occur, which can cause an electric shock and burns.

• Prior to performing any work on the inverter, always disconnect the inverter from voltage sources on the AC and DC sides as described in the inverter manual. When doing so, note that even if the DC load-break of the inverter is switched off, there will be dangerous direct voltage present in the DC conductors on the DC-in connecting terminal plate in the Connection Unit of the inverter.

Danger to life due to electric shock from touching an ungrounded product
Touching an ungrounded product can cause a lethal electric shock.

• Ensure that the product is integrated in the existing overvoltage protection.

Increased electromagnetic radiation through the antenna
During operation, the antenna produces an electromagnetic field and can interfere with other devices (e.g., pacemakers) due to electromagnetic interference.

• Persons must not remain closer than 20 cm (8 in) to the antenna for long periods of time.

Damage to seals on the enclosure lids in subfreezing conditions
If you open the enclosure lid of the Connection Unit when temperatures are below freezing, the enclosure lid seal could be damaged. As a result, moisture can get into the Connection Unit.

• Only open the enclosure lid of the Connection Unit if the ambient temperature is at least 0°C (32°F) and there is no frost.
• If the enclosure lid of the Connection Unit has to be opened at temperatures below freezing, any ice formation on the seal has to be removed (e.g by melting it with warm air) before the opening of the enclosure lid. Observe the applicable safety regulations.

Damage to the inverter or product due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter or the product through electrostatic discharge.

• Ground yourself before touching any component

Electrical installations
All electrical installations must be carried out in accordance with the local standards and the National Electrical Code®
ANSI/NFPA 70 or the Canadian Electrical Code® CSA C22.1.

• Before connecting the inverter to the utility grid, contact your local grid operator. The electrical connection of the inverter must be carried out by qualified persons only.
• Ensure that no cables used for electrical connection are damaged.

Mounting

Mounting Position and Cable Route

Mounting location
Increased electromagnetic radiation through the antenna
During operation, the antenna produces an electromagnetic field and can interfere with other devices (e.g., pacemakers) due to electromagnetic interference.

• Persons must not remain closer than 20 cm (8 in) to the antenna for long periods of time.

The mounting location of the antenna is crucial for the quality of the wireless connection. Radio waves are emitted in circles from the longitudinal side of the antenna. A circular dead spot begins at the tip of the antenna. If you place the receiver in this dead spot, the receiver cannot receive any radio waves from the antenna. Requirements for the mounting location:

• An antenna cable length of 3 m (9.8 ft) must be observed. The antenna cable must not be extended.
• The antenna cable must be placed in such a way that the minimum bending radius of 35 mm (1.38 in) is maintained.
• The receiver must not be in the dead spot of the antenna.

Mounting the Antenna
Damage to the inverter due to moisture ingress during electrical installation

• Never open the inverter when it is raining or snowing, or the humidity is over 95%.
• For attaching the conduits to the enclosure, only use UL-listed rain-tight conduit fittings or UL-listed conduit fittings for wet locations complying with UL514B.
• Seal all unused openings tightly

Electrical installations
All electrical installations must be carried out in accordance with the local standards and the National Electrical Code®
ANSI/NFPA 70 or the Canadian Electrical Code® CSA C22.1.

Procedure:

1. Danger to life due to high voltages of the PV array
   When exposed to sunlight, the PV array generates dangerous direct voltage. Touching the DC conductors can lead to lethal electric shocks. Even if the DC load-break switch of the inverter is in the O, position, there will be dangerous direct voltage present in the DC conductors and on the DC-in connecting terminal plate in the Connection Unit of the inverter.

   • Prior to performing any work on the inverter, always disconnect the inverter from voltage sources on the AC and DC sides and secure it against reconnection (see the inverter manual).
   • Leave the DC-in connecting terminal plate plugged into the Connection Unit of the inverter and only touch it on the black enclosure.
   • Do not remove the DC cable from the connecting terminal plate.

2. Attaching the cable gland on the inverter:

   • Push the sealing plug from the inside out of the second hole from the left in the inverter enclosure and retain it for future decommissioning.
   • Unscrew the counter nut from the supplied cable gland.
   • Screw the cable gland with the counter nut on the inverter enclosure opening

3. Connecting the antenna cable plug:

   • Unscrew the swivel nut from the cable gland.
   • Press the multi-hole seal out of the cable gland from the inside.
   • Route the antenna cable with the cable end with the plug through the swivel nut and the desired hole of the multihole sea
   • Push the multi-hole seal along with the antenna cable back into the cable gland. Ensure that any unused openings of the multi-hole seal are sealed with sealing plugs.
   • Screw the swivel nut of the cable gland on loosely.
   • Remove the protective cover of pin connector ANT. on the communication assembly (if present).
   • Insert the plug of the antenna cable into the pin connector ANT. on the communication assembly until it snaps into place. Observe the prescribed cable route (see Section 4.1, page 12).
   • Fasten the swivel nut on the cable gland hand-tight. This will secure the antenna cable.

4. Installing the antenna bracket:

   • Considering the dead spot of the antenna, move the antenna bracket to the desired position on the wall and hold it firmly.
   • Mark positions of drill holes if necessary and drill two holes with 6 mm (0.24 in) diameter each at the marked points and insert screw anchors.
   • Attach the antenna bracket to the wall with the screws.

5. Attaching the antenna cable and the antenna to the antenna bracket:

   • On the antenna cable, unscrew the counter nut approx. 5 mm (0.2 in) from the plug.
   • Lead the antenna cable plug from the antenna bracket’s slot. In doing so, make sure that the washer and the counter nut are on the outside of the antenna bracket and that the antenna cable is not kinked or twisted.
   • Tighten the counter nut.
   • Hand-tighten the antenna on the antenna extension cable plug

6. Danger to life due to electric shock from touching an ungrounded product Touching an ungrounded product can cause a lethal electric shock.

   • Ensure that the product is integrated in the existing overvoltage protection.

7. Close the inverter and recommission it (see inverter manual).
   ☑ The antenna is automatically recognized and activated by the inverter.
