0.2 Electrical Hazards
1 The electrical connection must only be provided by a trained person.
Please observe the national regulations in the country of use like
EN 50110-1 for Europe, for example.
2 Potentially lethal voltages are present at the mains connections. Before
beginning with any maintenance or service work on the pump, discon-
nect the pump from all power supplies (lockout/tagout). In addition,
there is the danger of residual voltage for up to 5 minutes after discon-
nection.
3 Install a device for a safe disconnection from the power supply.
4 High electric voltages! When touching parts at high electric voltages,
there is the risk of suffering severe injuries by an electric shock! Covers
marked with this symbol must only be opened by trained electricians
after having reliably deenergised (lockout/tagout) the equipment.
5 Note the information on the IP type of protection.
6 Always operate the pump with a properly connected protective earth
conductor and make sure that the motor casing is closed.
7 Observe the manufacturer’s information and operating instructions for
the respective frequency converter.
8 The pump must only be operated at the frequency specified for the
motor. For the WH 2500 use only the Leybold frequency converter.
9 For pumps with external frequency converter: after having connected
the motor and each time after having made changes to the wiring,
check the motor’s direction of rotation.
A wrong direction of rotation can cause a pressure buildup on the
intake side. Moreover, the pump may suffer severe damage.
10 Install a suitable motor protection for the electric motor before starting
up for the first time. Note the information in these Operating
Instructions and on the nameplate.
11 Before starting, check to ensure that the junction box is undamaged,
run a visual inspection on the seals.
12 Install add-on parts (pressure switches, for example) without any
mechanical tensions and protect these against being damaged by
impacts, for example.
13 Lay the connecting lines so that these cannot be damaged. Protect
the lines against humidity and contact with water. Avoid thermally
stressing the lines by unfavourable laying. Comply with the required
standards when designing and laying the electrical connections.
14 Provide strain relief for the connecting lines so that the plugs and the
line connectors are not subjected to excessively high mechanical
stresses.
15 Lay electric lines so that there is no risk of tripping over these.
