Fuse
A 2.5A - 240vac subminiature (Little Fuse Inc. part #37412500410 recommended) protects the power input circuit.
Each clock and signal relay circuit must be current limited to 8A or less by an external circuit breaker or fuse.
Clock Connections

To prevent damage to relays, relay contact voltage must not exceed 240vac
.
WARNING
To protect against shorts between power and signal circuits, all wires connected to the power, clock, and
signal circuit terminals must be insulated to 300vac.
Appendix I shows wiring connections to the master clock and the secondary clocks for all clock types controlled by
the AllSync IQ master.
Mounting Master Clock
The AllSync IQ master clock should be:
• Located indoors in a dry location
• Mounted upright on a vertical surface
• Protected from physical damage
• Protected from water, including condensation
• Out of direct sunlight
• Operated by trained personnel
An area at least 22" wide and 20 1 /
2
" high should be reserved to allow a clearance of at least 12" below and on left
side of the AllSync IQ master. Wiring for power, clock and signal circuits must enter through conduit knockouts along
the bottom of the enclosure. Connector for Ethernet and power switch are are located on the left side of the enclosure.
The AllSync IQ master is designed to be wall-mounted by a keyhole hanger and screws. The Quick Start Guide shows
a template for locating wall hangers to mate with these openings.
