2. Installation

Mounting the Enclosure.

Select and remove the appropriate knockout(s) on the ABS-8RF enclosure.

Securely mount the enclosure.

Ground the enclosure to a solid electrical ground per NEC Article 250.

Pull all wiring into the enclosure (refer to "UL Power-limited Wiring

Requirements" on page 17).

Wiring the Power Terminal Blocks

24 VDC power supplied by the host control panel or external power supply

must be regulated and power-limited. This power is inherently supervised (loss

of power also results in a communication failure at the control panel).

• Limit the total wire resistance to 10 ohms.

• Connect 24 VDC power from FACP or Power Supply to TB1-3 (+)

and TB1-4 (–).

• Connect earth ground (TB1-1

EARTH

) to a mounting screw on the

backbox or cabinet.
