QFlex is suitable for use with mains supplies with nominal voltages and frequencies in the range 100V – 240V and
50Hz/60Hz.
Each Qlex module will limit it’s mains inrush current to a worst case of 10A on 230V mains & 5A on 115V mains
QFlex is designed and intended for use in non-domestic situations. Mains power is to be supplied from a permanent hard
wired feed. The feed for each QFlex must be protected by a fuse or circuit breaker rated at no more than 10A. It must be
possible to isolate the feed to each QFlex by means of a double pole switch with a minimum of 3mm contact separation.
All wiring is to comply with local regulations.
Ensure that the QFlex is isolated from the mains supply by means of the above switch before any maintenance or
cleaning is undertaken.
