7. Strip off 6 mm (0.24 in) of the conductor insulation from each of the connection cable
conductors.
8. Trim unneeded insulated conductors of the connection cable flush with the cable sheath.
☑ The connection cable and the cable for shielding
have been prepared for connection.
6.3 Preparing the Enclosure Opening on the Inverter
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.
Additionally required material (not included in the scope of delivery):
☐ Desired number of connection cables (see Section 6.1 "Cable Requirements", page 15)
☐ If not yet present: 1 conduit: 25.4 mm (1 in)
☐ If not yet present: 1 rain-tight conduit fitting for wet locations complying with UL 514B:
25.4 mm (1 in)
Procedure:
1. Make sure that the inverter has been disconnected and is secured against reconnection (see
the inverter manual).
2. Push the sealing plug out of the enclosure opening and retain it for later decommissioning.
3. Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
4. Attach the conduit to the enclosure opening.
5. Lead the connection cable through the conduit into the inverter.
6.4 Connecting the Temperature Sensor
You can connect 1 outside temperature sensor and 1 module temperature sensor each to the
module. The measured values from the temperature sensors are shown on the user interface of the
inverter.
Additionally required material (not included in the scope of delivery):
☐ Up to 2 temperature sensors
☐ Up to 2 connection cables (see Section 6.1, page 15)
Requirements:
☐ The temperature sensor must be technically suitable for connection to the temperature input
(see Section 9, page 31).
