The RS969 family has 2 different power supply input connectors---Mini A-coded male connector or
M23 A-code male connector shown in Figure 2.2.1.1. The Mini power connector only has 4
terminals, so only one power supply source is allowed to connect to the RS969 with Mini power
connector; The M23 power connector has 5 terminal pins which means 2 power supply sources are
allowed to power the RS969 with M23 power connector.
The RS969 family supports dual redundant power supplies – "Power Supply 1 (PS1)" and "Power
Supply 2 (PS2)". The connections for PS1, PS2 are shown in Table1 and 2.
Refer to
Table 1 and 2 for a description of each terminal and sections 2.3.2 through 2.3.4 for wiring

internally in the RS969 family. There is also an additional
chassis ground screw and the chassis ground connects to
both power supply surge grounds via a removable jumper
shown in Figure 2.2.1.2 .
