CONNECTING THE CONTROL LINES
Figure 14: Control lines
The Q
F
ire system is delivered with "plug and play" connectors for the control lines. This innovation is de -
signed to make the installation of the fire brigade switch as easy and efficient as possible. The heart of this
innovation are the customer-specific pre-wired connections for the control lines. The control line from the
control box to the switch box(es) are no longer mounted on terminals in the housing. The installer only has
to mount the supplied mating plugs onto his control line and plug into the control box and the switch
box(es).
Proceed as follows:
1.
Interconnect the control box with the 1. switch box and further switch boxes with a control line ca-
ble 5 x 2.5 mm² (on site) 1:1.
2.
Both, control box as well as switch box -slaves (with power supply) must be connected to 230V
AC.
➔
With option surge protection device an appopriate grounding has to be installed.
3.
Check the system
function as follows:
➔
Turn on the control box main switch → all LEDs light up green.
➔
Measure the transmission at the MC4 plugs.
4.
Turn off the control box main switc
h.
5.
Connect the string lines to the switch box(es).
6.
Perform a functional test with PV and inverter(s) according chapter 5 START-UP, page 22.
