SMA POWER CONTROL MODULE - Manual (Page 17)

SMA Solar Technology AG 5 Electrical Connection
Installation Manual PWCBRD-10-IA-en-14 17
Procedure:
2. Dismantle the connection cable by 4 cm.
3. Trim unused insulated wires flush with the cable sheath.
4. Strip the wire insulation by 6 mm.
5. Connect the connection cable to the ripple control receiver (see ripple control receiver manual)
and write down the wire colours.
6. If you want to insert two cables through the cable gland M25 of the inverter, remove the cable
support sleeve of the cable gland. If necessary, loosen the swivel nut of the cable gland.
7. Lead the connection cable through the cable support sleeve with two holes and the cable gland.
Push the cable support sleeve with two holes into the cable gland.
Damage to the module due to high voltage
• Only connect a ripple control receiver with a relay that is exclusively supplied by the 12 V
output of the module.
Operating the SMA Power Control Module and the multifunction relay in the inverter
in parallel
• If you want to operate the SMA Power Control Module and the multifunction relay in
parallel, make sure that no more than 30 V DC or 25 V AC are connected to the
multifunction relay.

Danger to life due to electric shock from faulty connection of the ripple control
receiver
In the event of faulty connection of the connection cable to the ripple control receiver, mains
voltage may be present in the module.
• Do not connect insulated wires of the connection cable to the phase conductors of the
ripple control receiver.
• When connecting, ensure that no bridge is being used in the ripple control receiver.
