3.1 Power Supply Module (24V) Wiring

Voltage:

For terminal block connector wiring best practices, see

General Wiring Recommendations.

This is a Class 2 Product. Use a Class 2 transformer only (rated between

60 and 100VA at 24VAC) for each power supply module.

A separate transformer rated at 60 VA minimum must be

used for each power supply module (24V) for it to

operate at full capacity. Choose a transformer that can

supply both the needs of the power supply (60VA) and

any other 24VAC loads such as connected wireless

adapters: add up the maximum power consumption of

all loads and multiply this sum by 1.3.

Use an external fuse on the 24VAC side (secondary side)

of the transformer, as shown in the figure below, to

protect all modules against power line spikes and

mis-wiring.

Maintain consistent polarity when connecting controllers

and devices to the transformer. One terminal on the

secondary side of the transformer must be connected to

the building's ground. Ensure that the 24V COM termi-

nal of the power supply is connected to the grounded

transformer secondary connection.
