7.3 Connection of safety earth wire and 230V AC
See chapter 10 ‘Description of modules’, section 10.1, point X5 for further description.
7.4 Installation of the break glass unit, ventilation keypad and smoke
detector
Ensure that the break glass unit and the ventilation buttons are visible and well accessible.
Do not install behind protruding walls, door panels or hidden by the building structure.
Note: Installation height of the break glass unit 1.5 – 1,7m above floor.
Install the smoke detectors in accordance with their enclosed instructions
7.5 Assembly instructions
Always have assembly, installation, repair and maintenance of smoke and heat extraction systems carried out by
qualified personnel trained for this purpose.
Rules to be adhered to for setting up and installation
The following safety relevant rules have to be adhered to when planning the use of a smoke and heat extraction system
and its set-up and installation:
• The Provincial Building Ordinance of the provinces,
• The regulations of the competent fire protection authority,
Accident prevention regulations
Adhere to the general accident prevention regulations (APR), the APR for power operated windows and doors, and the
installation rules in your country.
CAUTION:
Live components are directly accessible after opening the system housing.
Prior to inserting / removing modules disconnect to the panel from the mains supply and the back-up batteries.
• adhere to the installation instructions and your local energy providers
• select the place of installation such that free access is guaranteed for maintenance purposes
• select cables according to regulations in this instruction - take the calculation of the motor supply cable lengths
into account when laying the cables
• power cables entered via the cable glands
• connect the cables in accordance with the drawings provided by the manufacturer
• route the cables in the building according to the regulations in this instruction
• after the smoke panel is installed the back-up batteries will be fully charged after ca. 8 hours
• check all system functions
Electric cable routing for smoke and heat extraction systems
Electrical cables always have to be laid in accordance with the national and local rules in your country.
Do not use the PE wire / green/yellow wire!
Cables of type NYM, concealed, can be used.
For surface laying, halogen free safety cables are recommended (see cable plan).
If possible, the use of cable types should be agreed with the Technical Services and the competent fire protection
authority.
For the maximum permissible cable lengths of the motor supply cables for the WSC 5XX system, taking the specified
cable cross sections into account (cable information for surface laying), please refer to chapter 8 “Cable dimensioning”.
8 Cable dimensioning
8.1 Maintaining the cable functions
According to valid national regulations.
The cable network for smoke ventilation systems (“Cable system“) ends normally at the interface (junction box) for the
actuator!
The flexible, heat resistant connection cable of actuator is part of the system component‚ electric motor actuation' and is
not a part of the electrical installation!
We recommend in all cases to discuss the type of cable routing with the competent fire fighting authorities.
8.2 Formula for the calculation of the maximum motor cable length
Max. cable length = permissible voltage drop 2V (UL) x conductivity of copper(56) x cable cross section in mm
2
(a)
max. motor current total in amps (I) x 2
Example
Max motor cable length with cable cross section 0.75mm
2
and actuator current 2A: (2 x 56x0.75) : (2 x 2) = 21m
