2.4.2.5Analogue Output Connection

WARNING Mains voltages are present in this instrument when power is connected. De-energise before opening front cover.

Plug PL1 on each input board is used for the analogue output. A 2-core screened cable is required and is connected into a 2-way socket such that:

∙The positive output conductor terminates in socket SK1 pin 1.

∙The negative output conductor terminates in socket SK1 pin 2.

Gain access to each PCB 24680501 and connect the analogue output cable as follows:

1. Pass the analogue cable through its gland (if applicable) and into the enclosure.

2. Prepare the analogue cable to give a stress- free run to PL1 on each PCB 24680501, allowing for a double-turn to pass through a ferrite.

Analogue wiring must not share cables with power input, electrode input, or relay output.

It is considered good practice to twist the analogue pairs together.

3.Use a good quality RF cable gland, and ensure there is a good annular (ring shape) connection with the screen. A ferrite (supplied) must be attached to each analogue pair inside the enclosure, as close to the cable gland as possible. Make a double-turn through each ferrite.

4.Prepare the conductor ends, fit the crimp connectors and connect the cores into their respective socket SK1 terminals.

5.Fit the socket into plug PL1 and check the cable run.
