Introduction

Attached Input Connections

All models use an IEC60309 input connector plug on a 3m (10 ft) cable attached to the rPDU. The type of input

connector plug varies by model to accommodate different amperage ratings and Delta or Wye configurations.

The input connector plugs have Ingress Protection (IP) ratings that specify the degree of environmental

protection for electrical equipment. All models use IEC60309 input connector plugs that are either splash

resistant (S) or waterproof (W).

NOTE:

Splash resistant plugs are IP-rated at IP 44, which means the plug is protected against solid objects less than

1.0 mm in diameter.

NOTE: Waterproof plugs are IP-rated at IP 67, which means the plugs are watertight, splashproof, and dust tight.

Standard IEC60309 reference codes provide a useful summary of the input connector plug specifications. The

code includes the number of pins, the maximum amperage rating, the type of connection, the alignment tab

clock position, and the protective classification.

Table 1 lists the standard IEC60309 reference codes for each model.

Circuit Breakers

NOTE: The DELLM0003 model does not have circuit breakers.

There are six 20A circuit breakers on the rPDU (two circuit breakers per phase protecting the group of outlet

receptacles for that phase). Circuit breakers on the rPDU trip automatically when a power overload is detected.

Standard rPDU circuit breakers have Type C trip characteristics.

The rPDU monitoring firmware provides warnings that there is potential for overload and alarms if an overload

occurs. These thresholds are user-configurable. To reset the breakers after an overload, flip the breaker switch to

the ON position.

Circuit breakers and outlet receptacles are numbered and color-coded on the front panel to show the association

between breakers and the receptacles they protect. The phases (L1, L2, and L3) and protecting circuit breakers

(CB1 through CB6) are labeled on both circuit breaker groups and outlet receptacle groups (see Figure 4).
