must be secured upstream of their connection sites such that the connection sites are strain- and
pressure-relieved.
Cables must be laid separately inside the device. The jacket must be left on the cables all the way to
the terminals.
Cable type NYM 3x1.5 or 3x2.5 must be used for power supply connection.
Any commercially available communication cables with or without shielding may be used for the
safety extra-low voltage lines.
The cable cross-section must be configured according to the current consumption of the devices
used and to the line length.
Power supply connection:
The cross-section of the power supply cord must not exceed 2.5 mm².
Hold-open system wiring:
Recommended line type: without smoke switch in combination with a smoke
status indicator switch status indicator
IY(ST)Y 2x2x0.6 IY(ST)Y 3x2x0.6
IY(ST)Y 2x2x0.8 IY(ST)Y 3x2x0.8
Maximum line length:
The maximum length of the line to the electromagnetic door retainer must not exceed 35 m and
that to the smoke switches must not exceed 75 m.
The number of line connections should be kept as low as possible. Every required connection must
be made by means of reliable methods. Clamped connections require the use of terminals with
pinch protection.
Do not place lines directly across the printed circuit board of the FSZ Basis.
