2103 Modem Module

Section 2 Installation and Operation

2.3 Installation

hazardous environments that can prove fatal for those unpre- pared. These spaces are governed by OSHA 1910.146 and require a permit before entering.

Follow the instructions below to install your 2103 Modem. Most of these instructions are similar for the 2103C and 2103G, but if you have one of those modules, read Section 3 or 4 for additional installation information.

2.3.1Latches - Locking and Latches must be operated to stack and unstack the modules in a

Unlocking

Series 2100 stack. The mechanisms are the same for the 2103

 

Modem and other 2100 Series modules. Detailed instructions

 

with photos can be found in your 2150 instruction manual.

 

Take a moment to familiarize yourself with operating the latches.

 

You must unlock the latch to place the module on top of another

 

module in a stack. The latch is unlocked by pushing in the latch

 

release on the right side of the module. To lock the latch, push in

 

the latch on the left side of the module.

CAUTION

The latch can be damaged by applying too much force. Never press on both sides at the same time. Do not force the latch if it is obstructed. While some degree of pressure must be applied to slide the latch, the ends of the latches should never bend more than 1/8”.

Note

Latches will “click” when they are fully locked and unlocked.

2.3.2Communication Connecting the 2103 Modem module involves uncapping and

Connectors

capping communication connectors. When a communication con-

 

nector is not in use, the connector should always be capped. The

 

cap will seal the connector to prevent corrosion, and will improve

 

communications.

 

When a communication connector is in use, store the cap on the

 

holder next to the connector. The communication connector will

 

be sealed by its mating connector.

 

Detailed instructions and photos can be found in your 2150 or

 

2110 instruction manual.

CAUTION

Caps PUSH ON and PULL OFF. Do not rotate the caps to remove them from the connectors.

Note

For modules to correctly stack and lock together, protective caps between the modules must be stored on the holders.
