===Connection of auxiliary equipment===
Expansion modules include Larnitech equipment connected through the CAN-bus. Such equipment includes: dimmers, RGB-backlit control modules, multimode sensors, etc. The equipment connected to the expansion port is defined automatically and does not require any preset tuning. Connector contact pin assignment is defined in '''Table 4'''. The example of connection is shown in '''fig. 21.'''

===Module installation and connection procedure===
<div class="caution">'''ATTENTION! You must precisely follow the recommendations listed in the Security Requirements section hereof.'''</div>
#Install the module in the switchboard on the DIN-rail and fix it with the special latch on the module base.
#Fasten the supply unit on the left side of the module.
#Connect the connector (8) having the noise filter pre-installed which is supplied complete with the module.
#Connect the connectors (9) – (14).
#Connect the connectors (1) – (5).
#Connect the connector (7).
#Apply power to the supply unit of METAFORSA module.
#Wait until the module is loaded, then configure it in accordance with the '''System Setup Instructions'''.
#Apply power to the connectors (1), (3), (5).
#Check all equipment for proper operation.
===METAFORSA module shut-off and deinstallation procedure===
#De-energize the module by disconnecting the circuit breaker assembly of the load power supply and METAFORSA module supply unit. Verify the voltage is absent on the terminals (1), (3), (5) of the connector wires and on the input terminals of the supply unit.
#Disconnect the load power supply connectors (1) – (5).
#Disconnect the connector (7).
#Disconnect the connectors (8)-(14).
#Remove the module from the DIN-rail, releasing the latch at the bottom of the module base.
