Note: Before working on any equipment, be aware of the hazards involved with the electrical circuitry and be familiar with the standard practices for preventing accidents.

To mount the batteries in the battery shelf, perform the following steps:

Mount the spacers (K) between the battery blocks (A), see Figure 1.
Place the safety strap through the slots in the battery shelf, see Figure 3.
Place the batteries on the shelf, see Figure 2. Make sure the front side of the batteries with the contact poles and the labels is facing the cabinet front.
Pull the batteries towards the shelf front edge.
Connect the batteries to each other by applying the connector bridge (H), plain washer (F), spring washer (G), by using the pole screws (C) from the batteries.
For measuring 12, 24, and 36 V DC insert three contact washers with flat lug terminals (E) on top of each connector bridge.
Tighten the six screws.
Apply the metal tube spacer (D), plain washer (F), spring washer (G), and 25-mm screw (B) on the plus pole of the rightmost battery block (do not tighten).
Apply the metal tube spacer (D), plain washer (F), spring washer (G), and 25-mm screw (B) on the minus pole of the leftmost battery block (do not tighten).
Position insulating pole covers (Y) on each of the four batteries, and press them down.
Place the strapping belt (L) around the batteries and tighten the strap, see Figure 3.
Fasten three warning labels, parallel connection of batteries (SVB 131 70), one on the right-hand side battery, and two at the bottom of the cabinet, see Figure 4 and see Figure 1.
