Powering up your IOLAN
NOTES:
1. For terminal# 1 through 7, strip insulation from wire 9/32-5/16 (7 -8mm) using stranded wire size 18-12 AWG.
Tighten screw to a torque of 4.5 Lb-in (0.51Nm).
2. For terminal# E (Chassis ground), the use of ring terminal size #8 (M4) is recommended using stranded wire size
AWG 18-14. Tighten screw to a torque of 12 Lb-in (1.36 Nm).
3. When power is applied, if both sources are available, both power LED 1 and LED 2 (on front of unit) will be
luminated indicating power detected from both sources.
4. Unit is suitable for installation as part of the Common Bond Network (CBN). The LDC’s power supply input terminals
are isolated from the equipment frame ground.
TELCO - NEBS Models
The Perle IOLAN LDC TELCO-NEBS models have been certified to be NEBS compliant.
To ensure compliance, power up the IOLAN LDC model and perform the following steps:
1.
Ensure that the power supply side of the connection is been powered down before attempting to
connect the wires on the IOLAN side.
2.
Connect the power as outlined in the “wiring” section below.
3.
Enable power to unit. Unit should now power up.
