• Before connecting the electric chain hoist, check whether the operating voltage and frequency specified on the type plate correspond to
the available power supply.
• Remove the cover from the control unit box.
Connection with direct control:
• Introduce the connection cable with cable gland M25 × 1.5 through the lower hole and connect in accordance with the attached
electrical chart to L1, L2, L3 and PE (see figure 2-1).
• With direct operated chain hoists without PMS relay contact is provided for connection of the brake. The brake must be switched on the
direct current side.
Connection with contactor control:
• Introduce the connection cable with cable gland M25 × 1.5 through the lower hole and connect in accordance with the attached
electrical chart to L1, L2, L3 and PE (see figure 2-2).
• Introduce the control cable through cable gland M20 × 1.5 in the hole below the housing and connect to terminals 1, 2, 3, 4, 10
(see figure 2-3).
When using a control switch:
• Strain relief to housing (see figure 2-4).
• Re-fit the cover from the control unit box.
• To maintain the predetermined protection class IP 65, all cables must fit into the corresponding cable glands and the cover
screws must be tightened after the connection with the torque specified in table 3.2.9.
• The control switch must be attached to the strain relief cord and not to the cable.
The protective conductor should not conduct any current during operation. With the installation of a motor protection breaker,
the current of the electric chain hoist must be observed in accordance with the type plate.
2.2.1 Electrical connections
Electrical installations may only be performed by authorised specialists.
The mains connection cable, the mains connection fuse and the main switch for connecting the electric chain hoist to the mains power
supply must be provided by the customer. A 4-wire cable with a PE protective conductor is needed as a supply line for three-phase versi-
ons. A 3-wire cable with a protective conductor is adequate for single-phase version. The length and cross-section must be appropriate for
the power consumption of the electric chain hoist. The wiring diagram is located in the lid of the electric chain hoist. In D8 PLUS electric
chain hoists, the power supply must be interrupted by means of a lockable switch, after reaching the desired position.
The control system must be fitted with an emergency stop button for monitoring. The power supply should be disconnected if the electric
chain hoist is not in use. Only experienced and competent users may operate lifting systems or individual electric chain hoists.
The principles per BGG 912/GUV-G 912 are to be applied. An inspection pass is to be created consisting of the installation documentation
from the manufacturer and the test records. Plans and descriptions for electrical installation are to be supplemented by the corresponding
control system constructor on a project-specific basis.inspection pass is to be created consisting of the installation documentation from the

2.2 Connections
The electric chain hoist must have the following identification:
• Electric chain hoist D8 .......................... : Triangle
• Electric chain hoist D8 PLUS ................ : Square
• Electric chain hoist C1 .......................... : Circle
Wherever possible, the electric chain hoist should be transported in its original packaging. The goods delivered should be checked for
completeness and the packaging disposed in an environmentally sound manner. It is recommended that the electric chain hoist is assem-
bled and connected on-site by qualified personnel. Use the type plate to check whether the electric chain hoist corresponds to the version
ordered (D8 / D8 PLUS / C1).
