Install the Switch Chapter 1
Attach the Power Connector
to the PoE Expansion Module
(optional) Follow these steps to connect the DC power source to the PoE expansion
module.
1. Insert the power connector into the DC input terminal block on the PoE
expansion module.
2. Use a screwdriver to tighten the captive screws on the sides of the power
connector.
Wire External Alarms
(optional) The alarm relays on the switch are normally open. To connect an external alarm
device to the relays, you must connect two relay contact wires to complete an
electrical circuit. Because each external alarm device requires two connections to
a relay, the switch supports a maximum of two external alarm devices.
Follow these steps to wire alarms.
1. Measure two strands of twisted-pair wire (18...20 AWG) long enough to
connect to the external alarm device.
2. Use a wire stripper to remove the casing from both ends of each wire to
6.3 mm (0.25 in.) ± 0.5 mm (0.02 in.).
ATTENTION: The input voltage source of the alarm circuits must be an isolated
source and limited to less than or equal to 24 V DC, 1 A.
For wire connections to the power and relay connector, you must use UL and CSA
rated, style 1007 or 1569 twisted-pair copper appliance wiring material (AWM)
wire (such as Belden part number 9318).
IMPORTANT Do not strip more than 6.8 mm (0.27 in.) of insulation from the wires.
Stripping more than the recommended amount of wire can leave
exposed wire from the power and relay connector after installation.
