Step 4 – Electrical connection
Single-phase power supply
15-25L models:
These models have single-
phase connection. No bridging is required.
40L models:
There are two connection
options:
• Single phase 220-240V. L1 and L2 need
to be bridged on installation. The single
phase supply must be sufficient to handle
the power of the unit (i.e. 25A or above)
• 3 phase connection (see below)
3-phase power supply
40L models:
There are two connection
options:
• Single phase 220-240V (see above)
• 3 phase connection 380-415V. 2 out of 3
phases are connected to L1 and L2. No
bridging between L1 and L2 is required
OR
