Connect earth ground

To help prevent damage from electrostatic discharges or other transient electrical surges,

connect the system to earth ground at the earth ground terminal before making other

connections. The

icon indicates the earth ground terminal. Use a recommended earth

ground reference, such as a grounding rod or a cold water pipe.

Notice!

Do not use telephone or electrical ground for the earth ground connection. Use 14 AWG (1.8

mm) to 16 AWG (1.5 mm) wire when making the connection. Do not connect other control

panel terminals to earth ground.

Caution!

Avoid electrostatic discharge. Always touch the earth ground connection with the icon first,

before beginning work on the control panel.

Configure OUTPUT A using the jumper

When planning your installation, carefully consider the use of OUTPUT A. OUTPUT A is a form

C relay. You can configure the common terminal (C) of Output A (OUTPUT A) using the

jumper:

– To provide +12 VDC (AUX power)

– To be a COM terminal (parallel to all COM terminals)

– To be a dry contact (no voltage, not common)

The control panel ships with the jumper in the default position, AUX power. (OUTPUT A, ‘C’

terminal using AUX PWR). Remove the door covering the jumper pins, and then move the

jumper to the left two pins for switched low (OUTPUT A parallel to COM terminals). Replace

the cover door. The OUTPUT A LED lights when OUTPUT A is active. Refer to the figure below

or to the B5512/B4512 Enclosure Wiring Label (P/N: F01U265442) to set the OUTPUT A

jumper.
