Installation Rollerblind Powered
8
• Where electric supply failures are possible, an emergency backup power supply
should be installed because the powered blinds do not have a manual control
function.
• Control devices (e.g. switches) must be installed in visible locations.
• The routing of cables through walls or bulkheads must be protected and insu-
lated by appropriate bushing, grommets or cable conduits.
• Secure all cables to prevent any contact with moving parts.
• Do not connect two or more motors to one switch as serious damage will occur.
• Do not connect one motor to two switches as serious damage will occur.
• Ensure cables are not damaged during installation.
• Ensure that the correct power supply is used for the supplied blind:
–12 Vg: Rated power 12 W
– 24 Vg: Rated power 19.2 W
– 230 Vw: Rated power 115 W
7.2 Notes on connecting to 12 V/24 Vg
Observe the following notes:
• Observe the cross section for cables:
– Motor cable: 0.5 mm
2
x0.5m
If the power supply unit is installed in a distance of more than 0.5 m, the cross
section must be adjusted to avoid a voltage drop of more than 3 %.
– Switch cable: 0.13 mm
2
x0.5m
• The motor control cable must be connected to a dry contact device. Any voltage
on the control wires will cause irreparable damage to the motor.
• If controlled using switches:
– Use a momentary, two independent (non interlocked), N/O + N/O single
pole switches.
– The operation of both up and down switches at same time will stop the
motor.
– Repeat action of switch stops the motor.
• If controlled using an automation system:
– Use a two single pole N/O dry contact relays.
– The operation of both relays stops the motor.
