Key Features

  • High voltage DC input 88 to 140 V DC
  • 2.5 A maximum full rack current draw
  • Half-height module directly behind power supply
  • No minimum rack load required
  • Under-voltage does not harm supply or PIM
  • Over-voltage causes fuse to open on PIM
  • Supply OK front panel LED indicator

Rack Configuration

  • Two half-height slots on left side of rack
  • Each slot accommodates one power supply
  • Both slots can hold power supplies simultaneously for redundancy

Installation & Wiring Guide

Wiring Checklist: Verify DC source voltage between 88-140V before connection. Use appropriately rated DC circuit breaker. Connect positive to + terminal, negative to - terminal. Torque terminal screws to 0.56 Nm. Install PIM directly behind associated power supply slot. Under-voltage does not damage module. Over-voltage opens internal PIM fuse.

Grounding: Connect rack ground terminal to plant earth ground using #10 AWG wire. Keep DC power cables away from signal wiring. Rack must have proper earth ground before power application.

Redundancy: Install two PIMs with two power supplies for redundant DC feed. Each PIM occupies one slot. Both can operate simultaneously. During replacement, remove failed unit after isolating DC source. Spare PIM slides directly in without rack power removal.

FAQs

Q1: What voltage range does 129478-01 accept?
A1: 88 to 140 V DC. Verify voltage at source terminals before connecting module. Over-voltage opens internal PIM fuse.

Q2: What torque for terminal connections?
A2: Torque terminal screws to 0.56 Nm. Loose connections cause voltage drop and heating. Use ring terminals for stranded wire.

Q3: Can I hot-swap the PIM?
A3: No. Isolate DC source before removal. Rack does not need power down. Replace failed PIM by sliding new unit into same slot.
