STEP PROCEDURE
AC Power Cord Installation
1. Use a supply cord fitted with a mains plug in accordance with local requirements.
Plug the AC supply cord into the IEC connector on the Type-4 PSU and secure
with retaining clip.
Note. Do not connect the plug to the supply socket until instructed to by the
Commissioning Test Procedure.
1. Fit the cover to the PSU without securing the screw or earthing the lid until
instructed to by the Commissioning Test Procedure.
PSU earthing
1. Note: The Type-4 PSU is double insulated. It still has a 3-pin IEC socket and
therefore uses a 3-wire cable and mains plug. There is no earth wire connected to
the IEC socket inside the unit.
Safety: Battery Handling
Care should be taken when handling lead acid batteries to avoid
dropping or short circuiting them. Disposal should be in line with local
codes. Batteries may explode if put into a fire. Install the batteries in the
PSU first, then connect them taking care to observe correct polarity.
Connect the blue lead first to connect them together, then connect the
red lead to the +ve terminal and the black lead to the -ve terminal.
