(5.6) mode of operation = continuous temperatures : the maximum operating temperatures of components used in this supply must not be exceeded after installation. the orientation of the supply, outpu t power, ambient temperature and the availability, amount, direction and/or restriction of natural airflow influences the tempe ratures of these components. thermal protection: the unit has a thermal protection circuit that wil l shut down the unit if an overtemperature condition is encountered. recovery is automatic. grounding: tb1-3 must be bonded to protective earth in the end application. the end application should be evaluat ed to ensure it meets the protective earthing requirem ent. overvoltage protection: the unit has overvoltage protection that is factor y set to trip at a maximum of 136% of the nominal output voltage. the unit must be cycle d off, then on to reset. 41-35627-0001, rev a 4/5/07 gem600/750 series installation instructions
explanation of symbols direct current attention, consult accompanying documents alternating current gem600/750 series installation instructions (contd.) current sharing: the optional built-in or-ing diode allows multiple units to share the load. note: adjacent units must be set within 0.2% of each othe r for proper current share. voltage adjustment: factory set to specified voltage. user accessibl e pot allows adjustment over a range of 5% of nominal voltage. the potentiometer is located on the a2 pwb located behind and above tb3. spacings: the required creepage and clearance distances from primary circuits to ground and secondary circuits m ust be maintained after installation to preserve the inten ded safety. warning! risk of fire! a blown internal fuse is an indication of catastro phic failure of circuit component(s). repair must be performed by sl power electronics authorize d personnel. airflow/cooling: the gem600/700 series is designed with an integra l fan rated 42 cfm. c o n n e c t i o n s ac input C tb1 status and control C j4 (amp p/n 64 0456-4) line 1 power good 1 neutral 2 power fail 2 reference to common ground 3 inhibit 4 dc output C tb2 and tb3 tb2 pins 1-3 main output output tb3 pins 1-3 rtn (common) options: a C terminal block (eby p/n 6002-03-n-01) (cooper m agnum a214203) b C bussbars t C phoenix contact (p/n 1732034) d - n+1 or-ing diode. will allow 2 or more power s upplies to be connected in parallel and share the o utput load. sl power electronics, corp.
