2.2. Power Supply Wiring and Grounding

Figure 2.2. M2000 Series Phillips Screw Terminal Block

The M2000 Family supports dual redundant power supplies - "Power Supply 1 (PS1)" and "Power

Supply 2 (PS2)". The connections for PS1, PS2 and the fail-safe relay are located on the terminal block

as shown in Figure 2.2, “M2000 Series Phillips Screw Terminal Block”.

The M2000 Family chassis ground connection, shown in Figure 2.3, “Chassis Ground Connection”,

uses a #6-32 screw. It is recommended to terminate the ground connection in a #6 ring lug, and to use

a torque setting not exceeding 1.7 Nm (15 in.lbs).

Figure 2.3. Chassis Ground Connection

The M2000 Family is equipped with a Phillips Screw Terminal Block. The Phillips Screw Terminal Block

has Phillips screws with a compression plate allowing either bare wire connections or crimped terminal

lugs. RuggedCom recommend the use of #6 size ring lugs to ensure secure, reliable connections

under severe shock or vibration. The terminal block has a safety cover which must be removed via

two Phillips screws before connecting any wires. The safety cover must be re-attached after wiring to

ensure personnel safety. Refer to Table 3 below for a description of each terminal as well as sections

5.2.1 through 5.2.3 for wiring examples.

Terminal # Description Usage

1 PS1 Live / +

PS1 Live / + is connected to the positive (+) terminal if the power source is

DC or to the (Live) terminal if the power source is AC.

2 PS1 Surge Ground

PS1 Surge Ground is connected to the Chassis Ground via a jumper on

the terminal block. Surge Ground is used as the ground conductor for all

surge and transient suppression circuitry. NOTE: Surge Ground must be

disconnected from Chassis Ground during HIPOT (dielectric strength)

testing.
