Warning:
Disconnect the mains supply and switch off the Q-
Controller when changing any of the wiring to the unit.
Be especially cautious when wiring high voltage to the
relays. Do not touch sensitive components on the circuit
card to prevent static discharge damage to the unit.

Mount Installation
It is recommended that controllers be installed 5 feet (1.5 m) above the floor, at
approximate eye level. Securely mount the Q-Controller using the appropriate screws.
The enclosure is a NEMA 4X rated enclosure and can be wall mounted with 4 screws. To
maintain the NEMA rating, it is important that the conduit opening is sealed upon
installation.

Power Requirements
The Q-Controller power supply voltage requirements are nominally 24VAC or 24VDC
NOTE: Input Power is half-wave rectifier circuit, it can be either non-grounded or
grounded. You will damage devices if you mix half wave and full wave rectifiers on
the same AC source. Use extreme caution when sharing a common AC source.
Sharing a common DC source is less problematic.
