Installation

Output

Outputs are capable of providing high currents for short periods of time for inductive load start-up or switching.

Fusing may be required for wire/loads if 2x Nominal O/P current rating cannot be tolerated.

Continuous current overload allows for reliable fuse tripping

Mounting

Simple snap-on system for DIN Rail TS35/7.5 or TS35/15 or chassis-mounted, optional screw mounting set

SDU-PMBRK.

Connections

Input & Output: IP20-rated screw terminals, connector size range: 16-12 AWG (0.5-4 mm2)

for copper conductors rated 90o , Torque 4.3 lb-in. (0.49 Nm).

Relay Contact Terminal Connections

IP20 screw terminals; connector size range: 24-16 AWG (0.34-4mm2)

Case

Fully enclosed metal housing with ventilation grid to keep out small particles.

Free Space

20 mm above, 35 mm below, 20 mm left/right, 10 mm in front

Notes:

1. See Battery Back-up Times on next page.

2. DC UPS System includes one power module (SDU 10-24 or SDU 20-24) and one or more battery modules (SDU 24-BAT or SDU 24BATEM)
