• To accommodate high in-rush currents, connect a time delay circuit breaker between the
facility power source and the load frame (refer to Table 2-3 on page 2-8).
The power cord set and plug is based on the voltage selection for the country to which the
frame is shipped and is compatible with the electrical requirements for that country.
5988 and 5989 Load Frames
Verify the following before proceeding with installation:
• The machine’s voltage is compatible with the main power supply to your facility.
• The machine’s power cable can reach the electrical power supply with some slack in the
cable. The power cable is 5.8 metres (19 ft) long.
• To accommodate high in-rush currents, connect a time delay circuit breaker between the
facility power source and the load frame (refer to Table 2-3 on page 2-8).
For models 5988 and 5989 the mains voltage must be in a “WYE” configuration with
neutral and ground. A Delta configuration requires an external Delta-to-Wye
transformer rated to a minimum of 5kVa. A rating of 7.5kVa is recommended.
The connector on the power cable must be compatible with the power source. If
the power cable supplied with your system does not fit your power source outlet,
add a male plug to the cable that is compatible with the voltage. Observe the CEE
wire color code as follows:
• Brown - high (live)
• Light blue - low (neutral)
• Green and yellow - earth (ground)
