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
