Bosch TR2000TF Series Installation And Operating Instructions Manual page 10

Installation instructions
• The power supply must only be connected after the water supply.
Connections must be carried out according to the circuit and terminal
diagrams. The ratings permitted by the power supply company for
primary/rapid heating, as well as the heating duration, must be
observed. The internal circuitry must not be altered. The rating plate,
norms, regulations and guidelines must be observed.
• Floor-standing water heaters have special connections on the
terminal strip for control cables and contactors.
• The protective conductor terminal is indentified by the protective
conductor sign.
• An all-pole disconnecting device with a min. 3 mm gap construction
must be fitted by the installation company.
CAUTION:
Attention!
▶ The appliance must not be connected by a two-pole-and-
earthing-pin plug.
Connection work
• Remove switchroom cap.
• Push power cable and control lead through the cable inlet and
connect in accordance with the circuit diagram.
• Connect the protective conductor to the protective conductor
terminal.
• Tighten the screwed connections of the cable inlets.
• Place the rating stickers in the position marked on the rating plate.
• Fit the switchroom cap.

When operating without a controller from the power supply company,
place a bridge between L1 and 5.
Depending on the power supply company, the period in which off-peak
power is supplied may be restricted.
Primary heating can therefore be set with selector switch b2, so that the
floor-standing water heater heats up in either 4 or 8 hours.
If the power supply company does not permit peak-rate heating, the
push-button must be covered with the plastic cap situated in the
switchroom.
