6.6 Connecting the Switch and Outlet for Secure Power

Supply Operation

Requirements:

☐ The technical requirements must be met for connecting the switch and outlet for secure power

supply operation (see Section10 "Technical Data", page61).

☐ 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):

☐ Conduits: 21mm (0.75in) or smaller with a proper reducing bush

☐ Rain-tight conduit fittings for wet locations complying with UL 514B: 21mm (0.75in) or

smaller with a proper reducing bush

Procedure:

• Connect the outlet for secure power supply operation.

• Connect the switch for secure power supply operation.

Connect the outlet for secure power supply operation

Requirements for the conductors:

☐ The conductors with regards to its ampacity, rated temperatures, operating conditions and its

power loss must be made in accordance with the local standards and the National Electrical

Code

ANSI/NFPA 70 or the Canadian Electrical Code

CSA C22.1.

☐ Conductor type: copper wire

☐ The conductors must be made of solid wire, stranded wire or finely stranded wire. When using

finely stranded wire, bootlace ferrules must be used.

☐ Conductor cross-section: 2.5mm² to 4mm² (14AWG to 12AWG)

Danger to life due to high voltages

• Ensure that the inverter is disconnected from all voltage sources (see Section8, page57

2. Remove the sealing plug from the enclosure opening for connecting the outlet for secure

power supply operation.

3. Insert the conduit fitting into the opening and tighten from the inside using the counter nut.

4. Attach the conduit to the conduit fitting.

5. Guide the conductors from the conduit into the inverter.

6. Connect the equipment grounding conductor of the outlet for secure power supply operation

to an equipment grounding terminal:

• Strip the insulation of the equipment grounding conductor by 18mm (0.71in).
