OPERATION
When the low temperature option is fitted an extra 100 cm space on the left-hand side of the system is required.
Unpacked, the largest subassembly will fit through a door aperture of 85 cm. Check the door aperture to ensure the system can be assembled in its designated area.
5.2.1.3 Electrical Services
A 3-phase 63 A supply with one 32A outlet and two 16A outlets. Additionally four single-phase outlets are required as described in drawing OD-01-00-015-C.
Use only the power cables supplied.
Do not connect the electrical power supply circuit to any other devices. Limit the electrical noise in the system by attaching the earth cable exclusively to an external earth terminal with a resistance of less than 0.5 ohms.
Fit a line voltage regulator if the power supply voltage fluctuates more than ±10 %.
Locate the mains outlet on the wall behind the system. The mains outlet should be of the circuit breaker type. (Outlet and connecting plugs are not supplied). The mains plug should be readily accessible by the operator when the equipment has been installed.
In areas where the mains power supply is unreliable an ‘uninterruptible power supply’ (UPS) is recommended. The UPS should have specifications of 10 kVA with 3-phase input and single phase output.
