hardware are provided. Inform factory sales representative or application engineer
of existing installation details when ordering.
Each LIM is supplied with a wiring harness complete with 15-pin header connector
(J-2). Ensure that power is disconnected prior to installation or any contact with
wiring harness or connectors. Header is polarized to prevent reverse connection.
Use caution when connecting or disconnecting header. Carefully align with pins
located on underside of LIM. Remove by securely holding header and pulling
straight down to avoid bending pins. Do not pull on wires as they may be
dislodged from header and adversely affect LIM operation.
Refer to wiring diagram below (Figure 2) for proper connection. Wiring connection
details are dependent on the various options installed, including RS-485 to Ethernet
converter for LIM-C

Notes:
1. Remote annunciators are ordered separately. A maximum of (3ea.)
remotes may be connected in parallel to a single LIM using up to the
maximum conductor length indicated. Consult factory for
applications requiring longer connection lengths.
2. Only connect LIM to PG LifeLink remote annunciator models and
accessories listed. Connection to unapproved equipment may void
warranty and cause severe equipment damage.
3. Alarm Relay contacts are rated up to 1A @ 30 VDC. Controls
contractor is responsible for supplying suitable power source and
