4.3 ELECTRICAL INSTALLATION
Electrical connection is done with connector supplied with the pump (pumps with power < 200W) or with a built in
connector for pumps with power rating above 200W (figure 4).
Fig.4
The pump has a built-in overcurrent fuse and protection, temperature protection and basic overvoltage protection. It
doesn’t need an additional thermal protection switch. The electrical power cables used should be capable of carrying
rated electrical current and should be properly fused. Ground lead connection is essential for safety. It should be
connected first. Grounding is only meant for pump safety. Pipes should be grounded separately.
