Mains; Connecting To Mains And Motor - Trane TR150 Quick Manual

Installation
3.2.1 IT Mains
CAUTION
IT Mains
Installation on isolated mains source, that is, IT mains.
Ensure that the supply voltage does not exceed 440 V
(3x380–480 V units) when connected to mains.
On IP20, 200–240 V, 0.25–11 kW (0.33–15 hp) and 380–480
V, IP20, 0.37–22 kW (0.5–30 hp) units, open the RFI switch
by removing the screw on the side of the frequency
converter when at IT grid.
1 EMC screw
Illustration 3.1 IP20, 200–240 V, 0.25–11 kW (0.33–15 hp), IP20,
0.37–22 kW (0.5–30 hp), 380–480 V
On 400 V, 30–90 kW (40–125 hp) and 600 V units, set
parameter 14-50 RFI Filter to [0] Off when operating in IT

mains.

For IP54, 400 V, 0.75–18.5 kW (1.0–25 hp) units, the EMC
screw is inside the frequency converter, as shown in
Illustration 3.2.
NOTICE
If reinserted, use only M3x12 screw.

3.2.2 Connecting to Mains and Motor

The frequency converter is designed to operate all
standard 3-phase asynchronous motors. For maximum
cross-section on cables, see chapter 6.4 General Technical
Data.
• Use a shielded/armored motor cable to comply
with EMC emission specifications and connect
this cable to both the decoupling plate and the
motor.
• Keep the motor cable as short as possible to
reduce the noise level and leakage currents.

then tighten the screws according to the torques
specified in chapter 3.2.1 Electrical Installation in
General.
Connect the mains supply to terminals L1, L2,
and L3, and then tighten the screws according to
