Electrical Connection; Establishing A 400 V Connection - HOLZMANN MASCHINEN TS315F1600 Instrucciones De Servicio

14.5 Electrical connection

Dangerous electrical voltage! The machine may only be connected to the
mains supply and the associated checks carried out by a qualified electrician or
under the instruction and supervision of a qualified electrician!
Immediately after making the electrical connection, check the running direction of
the band saw rollers. Observe the direction arrow on the machine. The running
direction is correct if the saw band runs from top to bottom. If this is not the case,
swap two phases, e.g: L1 and L2, on the mains plug.
The electrical connection is made via a switch-plug combination. This device must be operated
via a residual current circuit breaker.

14.5.1 Establishing a 400 V connection

To connect the machine to the electrical mains, proceed as follows:
 Use a suitable device to check the functionality of the zero connection and earthing.
 Check that supply voltage and current frequency correspond to the specifications on the
machine nameplate. A deviation of ± 5 % from the value of the supply voltage is per-
missible. For example, a machine with a working voltage of 380 V can work in the volt-
age range from 370 to 400 V. There must be a short-circuit fuse in the power supply of
the machine!
 For the required cross-section of the supply cable please refer to the current-carrying
capacity table.
 It is recommended to use a cable of type Н07RN (WDE0282), which must be protected
against mechanical damage.
 Connect the supply cable to the appropriate terminals in the input box (L1, L2, L3, N,
РЕ) - see the figure below. If a СЕЕ plug is present, the connection to the mains is
made via an appropriately supplied СЕЕ coupling (L1, L2, L3, N, РЕ).

14.6 Connecting to a dust collection system
The machine must be connected to dust collection system. The system must start
up at the same time as the motor of the band saw starts. For materials with a hu-
midity <12 %, the air velocity at the dust collector port and in the hoses must be at
least 20 m/s (for moist chips with a humidity >12 %, at least 28 m/s). The suction
hoses used must be flame-retardant (DIN4102 B1), permanently antistatic (or
grounded on both sides) and comply with the relevant safety regulations. Require-
ments for the dust collection system refer to the technical data.
