Notes:
- All aux inputs have input protection, the maximum input voltage should
not exceed 6 VDC.
- Analog systems will not monitor and/or alarm properly if the device that is
installed and configured operates outside the configured analog range.
- For proper digital input operation, use low impedance switches and wir-
ing. The total resistance should not exceed 200 Ω (ohms).
Directions to Wire Aux Inputs
WARNING: Disconnect external power to the unit before wiring.
AVERTISSEMENT : déconnectez l’alimentation externe de l’unité avant
d’effectuer un câblage quelconque.
1. Perform steps 1 - 4 of 5200A installation.
2. Open front panel - page 39 .
3. Feed aux device wires through drilled hole in rubber grommet to locations
K. Terminal strip is removable.
CAUTION: Run high and low voltage cables through separate bulkhead and
conduit.
4. Use (1) or (2) pin to terminate one wire and (G) to terminate ground wire.
(G) pin is the common ground for Aux 1 and 2.
CAUTION : Aux inputs are not isolated. Devices connected must be electrically
isolated from ground and the water.
