Preparing the data connection cable
If a data connection is required, use a standard RJ45 cable (patch cable) or construct an alterna-
tive data connection cable (Section 7.7, p. 54).
8.7
Connecting the inverter and switching on the AC power
Danger
Risk of death by electrocution! Observe the warning notes in Section 8.1, p. 57.
1. If necessary, establish a data connection:
– Connect the inverter and bus master using the data connection cable.
– Plug the optionally available termination plug into the open RJ45 socket in the last inverter.
2. Push the Multi-Contact MC4 opposing contacts of the DC cable firmly into the DC connections of
the inverter until they audibly click into place.
3. Insert the AC plug into the socket on the inverter until it audibly clicks into place.
4. Seal the AC connection as required. To do this, feed the tamper seal wire
through the counter-
nut
of the AC socket on the inverter (the counternut has a hole
) and through the opening
in the opposing plug
according to Fig. 11.
5. If locally prescribed, attach the ground cable to the stud bolt using the optionally available
grounding terminal ; see
in Fig. 5, p. 47. Do not exceed a torque of 6 Nm.
6. Switch on the AC line circuit breaker. The start page for initial commissioning is shown on the
display.
7. Perform initial commissioning and switch on the DC supply, as described in Sections 8.8 and 8.9.
