Follow these instructions and sound refrigeration engineering practice relating to installation, commissioning, maintenance and service. The compressor must only be used for its designed purpose(s) and within its scope of application (refer to «operating limits»). Consult Application guidelines and datasheet available from cc.danfoss.com Never operate c o m p r e s s o r without terminal box cover in place and secured. Under all circumstances, the EN378 (or other applicable local safety regulation) requirements must be fulfilled. Wear protective goggles and work gloves. The compressor must be handled with caution in the vertical position (maximum offset from the vertical : 15°). The compressor is delivered under nitrogen gas pressure (between 0.3 and 0.4 bar / 4 and 6 psi). Do not disassemble bolts, plugs, fittings, etc... unless all pressure has been relieved from the compressor.

VZH028 - VZH065 compressors can be powered by the dedicated variable speed drive or third party drive. When Danfoss drive is selected, check carefully for compatibility between compressor model and variable speed drive.

VZH028-044 VZH052-065 Basic connections - Depending on the frequency converter version, the physical position of individual connectors may differ from below diagram. - Always make sure that the compressor terminals T1, T2, T3 are connected to the frequency converter terminals 96, 97, 98 respectively. - The compressor motor cable must be shielded and the armoured part must be connected to ground on both cable ends; at the side of the compressor and at the side of the frequency converter. - Use an EMC cable gland for cable installation and perfect grounding; The metallic terminal box of the compressor has a paint-free surface around the connection hole for better conductivity. - A low pressure safety switch is mandatory to avoid compressor vacuum operation. - At start-up, verify that the compressor rotates in the right direction and pumps.
