Technical FAQs 4

Is DC voltage dangerous?

THIS SYSTEM CONTAINS BATTERIES Although the DC voltage is not hazardously high, the battery can deliver large amounts of current. Exercise extreme caution not to inadvertently contact or have any tool inadvertently contact a battery terminal or exposed wire connected to a battery terminal.

How many amps can a battery cabinet hold?

However, a maximum system current of 30 amps should be maintained regardless of the number of interconnected cabinets. The battery cabinet is designed to hold the batteries listed in Table 1. Operating Ambient Temperature Range: -40 °C to +65 °C. Storage Ambient Temperature Range: -40 °C to +85 °C.

What is a 211 -48 Vdc battery cabinet?

The NetSureTM 211 Series -48 VDC battery cabinet can be mounted in a 23” relay rack or mounted to a wall. The battery cabinet contains one (1) 40 A battery disconnect circuit breaker and provides alarm leads attached to the common contacts of the breaker. Battery cabinets may be daisy chained as shown in Figure 7 to increase the reserve time.

What is the role of DC cabinet in high-voltage switchgear cabinet?

Role of DC cabinet: It mainly provides power supply for high-voltage switch closing mechanism, the DC mini-bus on the top of high-voltage switchgear cabinet provides DC power supply for signaling, controlling, alarming and other circuits, as well as DC power supply for relay protection and automatic devices.
