Step 6 Wire Relay outputs
The 5X00 has eight (8) on board non-fused relays rated at 240VAC@5AMPs
(110VAC@10AMPs) of switching capacity. Relays energize and de-energize periph-
eral control, alarm and/or timer devices. Terminate relay device wires to Normally
Open (NO), Normally Closed (NC), and Common (C) sockets as required for the
application. (See 5X00 I/O Board wiring diagram on inside of front panel for iden-
tification of relay number and pin position.) Relays 1-4 are terminated at location
C on I/O Board. Relays 5-8 are terminated at location N on I/O Board - 3.21.
(Common lettering references are used for both 5400 and 5500 models).
CAUTION: Do not overload relay(s). Check manufacturer specifications for
inductive current/amp at power up. Use a contactor if necessary - figure 3.22.
(Common lettering references are used for both 5400 and 5500 models).
Directions to Wire Relay Outputs
WARNING: Disconnect external power to the unit before wiring. If any of the
relay contacts are connected to a “hazardous-live” circuit, ALL contacts on ALL
relays must be considered “hazardous live” and appropriately protected from user
contact outside the 5X00 enclosure.
AVERTISSEMENT : déconnectez l’alimentation externe de l’unité avant d’effectuer
le câblage. Si un contact de relai quelconque est connecté à un circuit sous ten-
sion dangereuse, TOUS les contacts de TOUS les relais doivent être considérés
comme étant sous tension dangereuse et doivent être protégés de façon adéquate
de tout contact de l’utilisateur hors du boîtier du modèle 5X00.
1. Perform steps 1-4 of 5X00 installation and step 5 as required for ap-
plication.
2. Open front panel - page 42.
3. Feed relay device wires through drilled hole in rubber grommet and to
locations C and/or N. The terminal strip is removable.
CAUTION : Run high and low voltage cables through separate bulkhead and
conduit.
4. Terminate relay device wires to the relay number (1-8) that will be con-
figured for device. Wire devices to NC or NO and C pins depending
on device configuration.
