Smart Glass is an electrical component and should be provided for in the electrical layout including the provision of fused spurs, switches, cable management and electrical connection boxes. All installations must meet the requirements of local regulations and guidelines and be carried out by a qualified electrician.
Any metal frames which may come into contact with the wiring of the panel MUST be earthed.
Smart Glass must NEVER be installed in direct contact with a metal frame.
If in doubt consult a qualified electrician prior to commencing any installation work.
Before installation commences bus bars (the electrical connection to the glass), connection leads and cables should be inspected to ensure the integrity of insulation.
Where ever possible it is recommended that the operation of Smart Glass is tested prior to commencement of installation.
Great care should be taken to ensure that exposed bus bars (the electrical connection to the glass), leads or cables do not come into contact with framework and any metal frames must be earthed and are totally sealed to prevent the ingress of moisture or water.
Smart Glass operates at 110VAC (110 volts alternating current), if the local mains voltage is higher than 110VAC a step down transformer is required. The Smart Glass Company manufacture and supply a range of thermally protected isolating transformers that are matched to meet the requirements of each installation.
Failure to use either Smart Glass Company’s transformers or those of an equivalent specification may result in irreparable damage to the Smart Glass. (Datasheets can be supplied upon request).
Multiple Smart Glass panels can be connected in parallel to a single transformer up to the maximum M2 rating of each transformer:
50VA – 2 M2
200VA – 10M2
500VA – 25M2
An RCD (Residual Current Device) with an MCB (Miniature Circuit Breaker) , or an RCBO (Residual Current Breaker with over-current protection)should be used along with a fused spur at the connection point for Smart Glass to provide local isolation.
It is imperative that the manual switch or remote control is wired into the circuit on the mains voltage side of the transformer; failure to observe this requirement may lead to irreparable damage of the Smart Glass panels.
Before turning on the power to a new installation the electrician must test the resistance reading between the frame and the bus bar feed cables to ensure that the reading resistance is infinite. If this is not the case the short circuit should be found and insulated accordingly.
