5.10.5 Clamping connection plates onto the batteries

There are a total of 11 different types of connection plates (see

Fig. 5–16

). Connection plates are always used when wires must be connected to cells with multiple battery terminals.

Attention!

We strongly recommend that you use original HOPPECKE connection plates when connecting wires to cells with multiple battery terminal pairs. Using other solutions may lead to overheating, risk of fire and increased electrical contact resistance.

Installation of standard connection plates

1. Screw the connection brackets onto the end terminals of the battery (see

Fig. 5–18 ).

Installing the end terminals

(connection plates)

Make sure that you do not cause mechanical damage to the terminals.

Attention!

2. First attach the screws by hand only so that you can make final adjustments to the cells, connection brackets and connection plates.

3. Fix the connection plate to the connection bracket of the battery with a torque of 20Nm

4. Afterwards tighten the pole screws using a torque wrench. The recommended torque is 20 Nm ± 1 Nm. Exception: 3 OSP.HC 105 with max. torque of 15 Nm.

It is very important to tighten screws thoroughly as a loose connection can become very hot and result in ignition or explosion.

Attention!

5.11 Connect the battery system to the DC power supply

Make sure that all installation work has been performed properly before connecting the battery system to the charging rectifier or UPS.

Attention!

1. Measure the total voltage (target value = sum of open-circuit voltages of the individual cells or monobloc batteries).

2. If necessary: label the cells or monobloc batteries visibly with continuous numbers (from the positive terminal to the negative terminal of the battery). HOPPECKE includes number stickers in your shipment.

3. Attach polarity labels for the battery connections.

4. Complete the identification plate in this documentation (see Chap. 1.2

).

5. Attach safety marking signs (these include: “Danger: batteries”, “Smoking prohibited” and, for battery voltages >60 V, “Dangerous voltage”). Attach further marking signs according to local requirements.

6. Attach the safety notices (see Chap. 0 ).

7. If necessary: Clean the batteries, the racks and the installation room.

Never clean batteries using feather dusters or dry towels.

Danger of electrostatic charging and gas explosion. We recommend cleaning the batteries using damp cotton cloths or paper towels.

Danger!
