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 7.

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

Block has Philips 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 4.2.1 through 4.2.3 for wiring examples.
